We have the four seasons, summer, spring, fall and winter because the Earth’s axis is tilted at an angle of 23.5, which means the Earth is always facing one side while the sun goes all around. Sometimes the Earth can be pointing towards the sun but other times ,not. The amount of sunlight around the Earth creates the seasons.

   Our solar system’s star is the sun.  The sun will eventually die because it will run out of hydrogen in its core.  There is only helium left for the sun when hydrogen runs out but the sun is not hot and dense to burn the helium.

The Earth’s axis is tilted and it is 23.5 degrees. This means that the Earth is always “pointing” at one side as it goes around and around the Sun. Sometimes, the Sun is in the direction of where the Earth is pointing, but not other times. The amount of sunlight that hits the Earth during the year, is what creates the 4 seasons on Earth. Each hemisphere experiences an opposite season.

There are  four seasons which are called  Spring, Summer, Autumn, and Winter. Seasons change throughout the year because of the way the Earth orbits  around the Earth. Each seasons has its own pattern of weather.

The sun is a star which the earth orbits and the light or warmth from the sun earth orbit.I didn’t know the sun can melt u and you are dead.It is very hot i would not want to go their.

The sun eventually will consume the earth and did you know one day the sun will be the same size as earth. It is interesting that it can fit 1 million earths. The sun is almost a perfect sphere. Did you know any of those facts i sure didn’t. I hope you guys are learning about the sun and tell it to your family. Very interesting!!!!!

We need the sun or else earth wouldn’t be the same, The solar system would not work correctly. The sun warms seas and earth would be lifeless without heat and light.It is unremarkable and it compares billions of suns. Did you know it generates space weathers. It gives us food to grow and oxygen that humans need.

I love all the interesting facts about the sun and the purpose of it. Oh sorry i forgot one more thing A person is most likely to die if your an adult without sunlight.That is all i have for you hope you like it. Sun has interesting fact like it is a star and same size of it.

Hi today i am going to tell you about the moon and the purpose of it. I hope you like it, I just want you to learn something about it. I like how the moon has a different shape every night. Enjoy and learn new facts you learn about.

People have questions how and why was it created well i can tell you the answer. Scientist believe the moon was created when an object smashed into early earth. Also I have a theory that the moon was created by the solar system and the sun as well. Did you know the moon is not a planet, but it is a satellite of earth. Did you learn some things i sure did, I have more.

Did you guys know the surface of the areas moon is 14,658,000 square miles or 9.4 billion acres and i searched up that 59% of the moon’s surface is visible from earth. The moon rotates 10 miles per hour comparing it to the earth’s rotation of 1000 miles per hour, in earth the moons other side is always hidden. Have you ever wonder if the moon has a magnetic field well if you say yes then you are wrong because it does not have one at all. In china the moon’s dark shadow is called “the toad in the moon”.

I have wonder why do we need the moon and we need it because only if we want life to continue. I hope earth is still here in the future and the rest of the time, I don’t like that every year we have the eclipse. That is all that i know i could not find anything else. Hopefully you learned a little bit more.

In conclusion i have taught you everything i know. I love all the interesting facts like you do. Enjoy my facts about the moon.

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– the plane of Earth's orbit around the sun. The tilt in the axis of the Earth is called its obliquity by scientists. It is true that Earth’s orbit is not a perfect circle. It is a bit lopsided. During part of the year, Earth is closer to the sun than at other times.

The Moon (or Luna) is the Earth’s only natural satellite and was formed 4.6 billion years ago around some 30–50 million years after the formation of the solar system. The Moon is in synchronous rotation with Earth meaning the same side is always facing the Earth. The first unmanned mission to the Moon was in 1959 by the Soviet Lunar Program with the first manned landing being Apollo 11 in 1969. The fifth largest moon in the solar system, Earth's Moon is the only place beyond Earth where humans have set foot. The brightest and largest object in our night sky, the Moon makes Earth a more livable planet by moderating our home planet's wobble on its axis, leading to a relatively stable climate.

The four seasons are winter, spring,summer, and autumn. We have those seasons because how the earth is tilted while it make its way around the sun. Each season has it on axis.

Picture: 

The moon is the fifth largest moon in the Solar System. The moon formed 4.6 years ago and some were around 30-50 million years after the formation of the Solar System. The diameter is 3,475 and the mass is 7.35x10^22 kg(0.01 Earths.) The surface temperature is -233 to 124 Celsius. In reality, the both sides of the moon has the same amount of sunlight however, only one side of the moon is ever seen from the Earth.

Why Do We Have The Four Seasons?

In many parts of the world, the year is made of 4 seasons which are summer, winter, spring, and autumn. My favorite season is summer because you go to the beach or pool and eat ice cream. We have the 4 seasons because it is the most important reason why seasons occur.

 Now you might be wondering, what is the moon and what does it do?The moon is a bright and huge ball that you would see in both the day and the night time. It is easier to see it in the night time though because it is closer to the earth and is very bright in the night time. The sun and the moon create tides which are gravitational pulls and when the moon is pulling on the oceans the sun is pulling it back. However the moon creates bigger waves than the sun because it is much closer to us than the sun. Our moon however rotates our earth and so do we. And so the tides change each day by 50 minutes a day.

The sun is the biggest star in the Solar System. If you could take apart the Sun and pile up its different elements, you’d find that 74% of its mass comes from hydrogen. with 24% helium. You could fit 1.3 million Earths inside the Sun. You could fit 1.3 million Earths inside the Sun. Over one million Earths can fit the huge Sun! In human history, the sun has been worshiped and feared. The surface area is 11,990 times the Earth!

There are in total four seasons in the world.  They are winter, spring, summer, and autumn.  But autumn is also known as fall.  The four season change depending of how much sunlight reaches the Earth and how much the Earth titles. For example, when the Earth’s axel is titled to 23.5 degrees the sun is facing only one side of the Earth. As a result, the opposite of the Earth (doesn’t have much sunlight) is at the season winter. As for the side facing the sun (has lots of sunlight) is in the season summer. In conclusion the seasons change depending on how much sunlight it receives from the sun.

The Sun is a big star that is the center of the solar system. It is  very hot and is basically the warming of our planet earth. Sometimes it would be too warming especially in the summer.. The sun is a star that the earth orbits. We should really thank the sun because it is the warmth of the earth. The sun is the biggest thing in the solar system. If we didn’t have the sun by our side, we could freeze to death.

Black holes are the points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can escape the powerful tug of a black hole's gravity.At the center of our galaxy, a super massive black hole churns. Because black holes swallow all light, astronomers can't spot them directly like they do the many glittery cosmic objects in the sky. But there are a few keys that reveal a black hole's presence. Black holes are also messy eaters, which often betrays their locations. Scientists think that ever since the universe began it is when the black hole also began.

Black holes are very interesting in space.There are four types of black holes, stellar, intermediate, supermassive, and miniature.The most common black hole is the Stellar death, if a Supernova happens,thousands of black holes will lurk in our galaxy.The black holes force is so strong that light that goes in can’t come out.The event horizon is where physics goes crazy. ... A singularity is what all the matter in a black hole gets crushed into, that is what is inside a black hole.You probably won’t get to see what is inside a black hole because you will be torn apart before you get to the event horizon, but if you pass it then you will see just black.

  Black holes are like a place in space where it is able to suck up anything such as stars, satellites, and even planets.  So what if earth encountered a black hole. My hypothesis is that it will destroy earth by sucking it up. Well, it’s a good thing that they are really far, far, away from us. This is what I think about black holes.

The Sun is the star at the center of the Solar System. It is a nearly perfect sphere of hot plasma, with internal convective motion that generates a magnetic field via a dynamo process. It is by far the most important source of energy for life on Earth.
