The earth is spinning on a diagonal axis which makes it such that one part of the earth is facing toward the sun and getting more heat. The other part of the earth is facing away from the sun and receiving less heat. The rotational axis is what causes the changes in days and it also happens over the course of a year. This causes all of the seasons. The southern hemisphere is usually warmer throughout the year and the northern hemisphere is cooler.

# data[].attributes.body
Rotation is when something spins around an axis and we have different weathers becuase the earth is tilted and not straight and when the northern hemisphere is facing the sun it has summer but the southern hemispher is having winter

Seasons are caused by Earth's tilted axis. While the rotation and revolution of the Earth goes on, different parts of Earth receive the Sun's rays. Because of this, when the North Pole is tilted towards the Sun, it's summer in the Northern Hemisphere and when the South Pole does so, it's winter.

Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.

Earths Rotation is the circular movement of the Earth on its axis and due to the rotation quality of our planet Earth we experience Day and Night. The reason for this? The reason is because different parts of the planet is facing towards the sun or away from it and it takes 24 hours for the world to turn all the way round to make a full day. Although the Earth is rotating on its axis it also revolves around the sun which is known as revolution and one full orbit around the sun is a revolution and the Earth takes 365 days to make a full revolution. Due to the Earth's tilted axis, revolution causes the seasons so if the Northern Hemisphere is tilted towards the Sun it is summer and the days are longer and the Southern Hemisphere experiences winter and the days are shorter.

It's all about Earth's tilt!

Many people believe that Earth is closer to the sun in the summer and that is why it is hotter. And, likewise, they think Earth is farthest from the sun in the winter.

Although this idea makes sense, it is incorrect.

It is true that Earth's orbit is not a perfect circle. It is a bit lop-sided. During part of the year, Earth is closer to the sun than at other times. However, in the Northern Hemisphere, we are having winter when Earth is closest to the sun and summer when it is farthest away! Compared with how far away the sun is, this change in Earth's distance throughout the year does not make much difference to our weather.

There is a different reason for Earth's seasons.

Earth's axis is an imaginary pole going right through the center of Earth from "top" to "bottom." Earth spins around this pole, making one complete turn each day. That is why we have day and night, and why every part of Earth's surface gets some of each.

Earth has seasons because its axis doesn't stand up straight.

But what caused Earth to tilt?

Long, long ago, when Earth was young, it is thought that something big hit Earth and knocked it off-kilter. So instead of rotating with its axis straight up and down, it leans over a bit.

By the way, that big thing that hit Earth is called Theia. It also blasted a big hole in the surface. That big hit sent a huge amount of dust and rubble into orbit. Most scientists think that that rubble, in time, became our Moon.

As Earth orbits the sun, its tilted axis always points in the same direction. So, throughout the year, different parts of Earth get the sun's direct rays.

Sometimes it is the North Pole tilting toward the sun (around June) and sometimes it is the South Pole tilting toward the sun (around December).

It is summer in June in the Northern Hemisphere because the sun's rays hit that part of Earth more directly than at any other time of the year. It is winter in December in the Northern Hemisphere, because that is when it is the South Pole's turn to be tilted toward the sun.

As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons. When the earth's axis points towards the sun, it is summer for that hemisphere. When the earth's axis points away, winter can be expected. Since the tilt of the axis is 23 1/2 degrees, the North Pole never points directly at the Sun, but on the summer solstice it points as close as it can, and on the winter solstice as far as it can. Midway between these two times, in spring and autumn, the spin axis of the earth points 90 degrees away from the sun. This means that on this date, day and night have about the same length: 12 hours each, more or less.

Why should this tilt of the Earth's axis matter to our weather? To understand this, take a piece of paper and a flashlight. Shine the light from the flashlight straight onto the paper, so you see an illuminated circle. All the light from the flashlight is in that circle. Now slowly tilt the paper, so the circle elongates into an ellipse. All the light is still in that ellipse, but the ellipse is spread out over more paper. The density of light drops. In other words, the amount of light per square centimeter drops (the number of square centimeters increases, while the total amount of light stays the same).

The same is true on the earth. When the sun is overhead, the light is falling straight on you, and so more light (and more heat) hit each square centimeter of the ground. When the sun is lower in the sky, the light gets more spread out over the surface of the earth, and less heat (per square centimeter) can be absorbed. Since the earth's axis is tilted, the sun is higher when you are on the part of the earth where the axis points more towards the sun, and lower on the part of the Earth where the axis points away from the sun.

For the Northern Hemisphere, the axis points most toward the sun in June (specifically around June 21), and away from the sun around December 21. This corresponds to the Winter and Summer Solstice (solstice is Latin for "the sun stands"). For the Southern Hemisphere, this is reversed.

For both hemispheres, the earth is 90 degrees away from the sun around March 21 and then again around September 21. This corresponds to the Fall and Spring Equinox (equinox is Latin for "equal night"). Everyplace in the world has about 12 hours of daylight and 12 hours of night.

So why are sunrise and sunset not exactly 12 hours apart on the Equinox?

Day and night are not exactly of equal length at the time of the March and September equinoxes. The dates on which day and night are each 12 hours occur a few days before and after the equinoxes. The specific dates for this occurrence are different for different latitudes.

On the day of the equinox, the geometric center of the Sun's disk crosses the equator, and this point is above the horizon for 12 hours everywhere on the Earth. However, the Sun is not simply a geometric point. Sunrise is defined as the instant when the leading edge of the Sun's disk becomes visible on the horizon, whereas sunset is the instant when the trailing edge of the disk disappears below the horizon. At these times, the center of the disk is already below the horizon. Furthermore, atmospheric refraction (or bending) of the Sun's rays cause the Sun's disk to appear higher in the sky than it would if the Earth had no atmosphere. Thus, in the morning, the upper edge of the disk is visible for several minutes before the geometric edge of the disk reachs the horizon. Similarly, in the evening, the upper edge of the disk disappears several minutes after the geometric disk has passed below the horizon.

For observers within a couple of degrees of the equator, the period from sunrise to sunset is always several minutes longer than the night. At higher latitudes in the Northern Hemisphere, the date of equal day and night occurs before the March equinox. Daytime continues to be longer than nighttime until after the September equinox. In the Southern Hemisphere, the dates of equal day and night occur before the September equinox and after the March equinox.

When are the times and dates of the next equinoxes and solstices?

Is it true that you can stand an egg on end during the Spring Equinox?

The answer is YES. However, you can stand an egg on end, with a large amount of patience, on any day of the year. This idea seems to pop up every year around the equinox. The thought that an egg can only stand on end on the spring equinox due to gravitational forces of the sun being aligned with the earth sounds like science, but it isn't. According to Chinese tradition, an egg can be made to stand on end at the precise moment winter ends and spring begins. But, the Chinese calendar had this transition occurring at a variable time each year, determined partly by the Chinese lunar month, usually in early February. More recently, this thought became fixed to the time of the spring equinox.

The underlying assumption relating to standing eggs on end is that there must exist some special gravitational balance. There are many forces acting on an egg when you try to stand it on end on a flat surface. Some people think that the gravitational pull of the Sun becomes balanced with that of the Earth to allow for this phenomenon to occur. However, the Moon exerts a much stronger gravitational effect on the Earth than the Sun, dominating the ebb and flow of the ocean tides. The Moon's effects are different at each of the equinoxes however. The most dominant force of gravity on a standing egg is the one between the Earth and the egg itself. This is determined by the weight of the egg and the force pulling the egg to the counter top.

If you want to prove this to yourself, take a fresh, uncooked egg and hold it with the larger end resting on a table or counter top. Wait for the fluid content of the egg to settle, then carefully test the balance. Be patient as you find the point where you can ever so gently let it go to remain standing on end.

The Earth orbits the sun once every 365 days and rotates about its axis once every 24 hours. Day and night are due to the Earth rotating on its iaxis, not its orbiting around the sun. The term 'one day' is determined by the time the Earth takes to rotate once on its axis and includes both day time and night time.

As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons.

Today's equinox signals the change of season, from summer to fall in the Northern Hemisphere and in the Southern Hemisphere from winter to spring. But why do Earth's seasons change?
September equinox: All you need to know
Some assume our planet's changing distance from the sun causes the change in the seasons. That's logical, but not the case for Earth. Instead, Earth has seasons because our planet's axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane, that is, the plane of Earth's orbit around the sun.

The tilt in the axis of the Earth is called its obliquity by scientists.

Over the course of a year, the angle of tilt does not vary. In other words, Earth's northern axis is always pointing the same direction in space. At this time, that direction is more or less toward the star we call Polaris, the North Star. But the orientation of Earth's tilt with respect to the sun - our source of light and warmth - does change as we orbit the sun. In other words, the Northern Hemisphere is oriented toward the sun for half of the year and away from the sun for the other half. The same is true of the Southern Hemisphere.

When the Northern Hemisphere is oriented toward the sun, that region of Earth warms because of the corresponding increase in solar radiation. The sun's rays are striking that part of Earth at a more direct angle. It's summer.

When the Northern Hemisphere is oriented away from the sun, the sun's rays are less direct, and that part of Earth cools. It's winter.

Seasons in the Southern Hemisphere occur at opposite times of the year from those in the Northern Hemisphere. Northern summer = southern winter.

The tilt in Earth's axis is strongly influenced by the way mass is distributed over the planet. Large amounts of land mass and ice sheets in the Northern Hemisphere make Earth top-heavy. An analogy for obliquity is imagining what would happen if you were to spin a ball with a piece of bubble gum stuck near the top. The extra weight would cause the ball to tilt when spun.

Over long periods of geological time, the angle of Earth's obliquity cycles between 21.1 and 24.5 degrees. This cycle lasts approximately 41,000 years and is thought to play a key role in the formation of ice ages - a scientific theory proposed by Milutin Milankovitch in 1930.

The Earth is currently decreasing in obliquity. Decreases in obliquity can set the stage for more moderate seasons (cooler summers and warmer winters) while increases in obliquity create more extreme seasons (hotter summers and colder winters). Glaciers tend to grow when the Earth has many cool summers that fail to melt back the winter snows. Remember, we're talking about a 41,000-year cycle here, so these changes in obliquity are not the primary driver of Earth's climate in the century ahead. Temperatures on Earth are influenced not just by obliquity, but also by many more factors which drive our complex climate system and the global temperatures we experience from year to year.

Other planets in our solar system also tilt at various degrees. Uranus rotates almost sideways at 97 degrees and has extreme seasons. The axial tilt on Venus is 177.3 degrees. Hence, Venus has very little in the way of seasons.

Earth's distance from the sun does change throughout the year, and it's logical to assume that an increase or decrease in a sun-planet distance could cause a cyclical change in the seasons. But - in the case of our planet - this change is too small to cause this change.

Our seasons change due to our planet's angle of tilt - 23.5 degrees - relative to our orbit around the sun. If Earth did not tilt at all, but instead orbited exactly upright with respect to our orbit around the sun, there would be minor variations in temperature throughout each year as Earth moved slightly closer to the sun and then slightly farther away. And there would be temperature differences from Earth's equatorial region to the poles. But, without Earth's tilt, we'd lack Earth's wonderful seasonal changes and our association of them with the various times of year - associating a fresh feeling in the air with springtime, for example.

It's easy to imagine a planet that has a more pronounced change in its distance from its star as the planet orbits the star. Some extrasolar planets - planets orbiting distant stars - have been found with more extreme orbits. And even in our own solar system, for example, the planet Mars has a more elliptical orbit than Earth does. Its distance from the sun changes more dramatically through its year than Earth's does, and the change in Mars' distance from the sun does cause some more pronounced cyclical changes on this red desert world.

Bottom line: It's logical to assume our planet's changing distance from the sun causes the change in the seasons. But Earth's distance from the sun doesn't change enough to cause seasonal differences. Instead, our seasons change because Earth tilts on its axis, and the angle of tilt causes the Northern and Southern Hemispheres to trade places throughout the year in receiving the sun's light and warmth most directly.

We have different seasons because the earth is tilted. Instead of standing standing straight up and down it leans in a little beat. The earth travels around the sun every year. We have 4 different seasons: Winter, Summer, Autumn and Spring. When the earth is tilted towards its summer and when its tilted away its winter and when its in between we have spring and autumn

Different Seasons are caused due to the tilt of the Earth on its axis. The Earth is bent at a 23.5 on its revolution or orbit around the sun. The 4 seasons are Spring, Summer, Autumn, Winter. The Earth rotation is different because it causes days of the week. As the Northern Hemisphere (The top part of the Earth) is facing away from the Sun meaning its cold or Winter, the Southern Hemisphere (bottom  part of the Earth) is facing the Sun or is Summer or hot due to the slight tilt.
