The 4 seasons is created because of the tilt of our the earth. Bill Nye says if we are in summer, the opposite side of the world is winter. The poles are the coldest because it´s farthest away from the equator. The seasons help balance weather in the world. Solar radiation is a big part of the seasons being created.

There are four different seasons in Earth: Winter, Spring, Summer, and Fall. In Winter, the temperature gets colder and snow may begin to fall. The days get closer and many plants stop growing. In the Spring, the weather gets warmer and the days get longer. Trees and plants grow leaves and flowers. In the Summer, the weather is warm and sunny and the days are long and sunny. Trees, plants, and flowers grow the most during this season. In the Fall, the days are shorter and it gets darker earlier. Leaves fall from trees and animals will start to prepare for the Winter.

The four seasons are spring, summer, fall/autumn, and winter.  Spring is in (March, April, May), summer is in (June, July, August), fall/autumn is in (September, October, November), and winter is in (December, January, February).  The four seasons happen because the tilt of the Earth’s axis.  The seasons all change throughout the year because it’s the way the earth moves.  In winter, Earth is the farthest away from the sun and in summer, Earth is the closest to the sun.

The Moon is the fifth largest moon in the Solar System. The brightest object in the night makes Earth a livable planet. The moon causes tides in the ocean guiding humans for thousands of years. Scientists think that a Mars - sized body collided with Earth which formed the moon. The moon has been here since prehistoric times maybe even before that!

The sun can fit over 1 million Earths.  We need the sun to survive because it provides us heat and light.  The heat can help us because it can transfer heat to the plant and the plants gives us oxygen.  The sun is approximately about 4.603 billion years old.  The sun is the star at the center of all the planets/ the solar system.  The sun’s temperature is about 10,000 Fahrenheit (5,600 Celsius).  The sun takes over 99.86% of the mass in the solar system.  The sun’s composition is hydrogen and helium.

The moon was formed 4.6 billion years ago and is Earth’s only natural satellite. The moon is the closest star to Earth and because of this we are able to gain a lot of knowledge about it. The moon has no atmosphere and has only been walked on by 12 people (all males). The moon orbits the Earth and it takes about 27 days for the moon to fully orbit the Earth. The moon also has quakes that are caused by the gravitational pull of the Earth. Scientists think that the moon has the same molten core as Earth.

A big purpose of the moon is to light up the night. The moon reflects the sun's light on to us even when the sun is on the other side of the earth. The amount of reflected light depends on the moon's surface area, so we are fortunate to have a moon that is so large.  Our moon is the fifth biggest moon in the solar system and the moon is approximately 4.53 billion years old.  On July 20, 1969, Neil Armstrong became the first human to step on the moon.  Armstrong and Aldrin walked around the moon for 3 hours.

The sun is one of the most important objects in our solar system, and allows us to live in more ways than one, offering heat and energy to many of us organisms. Don’t worry about the sun dying!  The sun is predicted to die in 5 billion years.  Didn’t know that, huh?  So next time, look up at the night sky and try to remember these facts! The sun is really more than just a flaming ball of gas.  It also has carbon, nitrogen, oxygen and plasma, becoming one of the largest sources of energy.  At 27,000,000℉ at its maximum temperature and over one million time larger than our Earth, The sun fuels most, (not all of the) life on Earth, giving plants food to grow to become food for other organisms, giving them the energy they need to survive!

There are four seasons of the year: autumn, winter, spring, and summer. The seasons happen because of the Earth’s axis is tilt at a certain way. At different times a year, the sun’s light will hit the Earth at different parts more directly. All the seasons have different characteristics that changes the world. Such as in the fall, trees lose their leaves to get ready for the winter. Autumn starts on September 1, Winter starts on December 1, Spring starts on March 1, and Summers starts on June 1.

The Sun by Jayden Chu

# data[].attributes.body
The sun is a star, near perfect ball of plasma. The diameter of the sun is 1.39 million kilometers The mass of the sun is 330,000 times the mass of earth. The sun is the largest object in the solar system. The sun is about 4.5 billion years old. The sun is going to burn out, but not in a long time. In about 5 billion years(longer than the age of the sun) the sun will run out of hydrogen fuel. The temperature of the sun’s surface is about 10,340 degrees Fahrenheit (5,726 degrees Celsius).

Over human history, the Sun has been worshiped greatly and without the sun, animals and therefore humans could not grow because animals needed food like vegetables and fruits to eat in order to grow. The Sun provides energy for plants to grow and therefore for animals and humans to grow. The Sun is a main sequence star which is a star composed of two gases; hydrogen and helium. The Sun is much bigger than the Earth and 11,990 times the surface area of the Earth.

The sun is a star over 4.6 billion years old, 92.96 million miles away from our home planet Earth, and is located at the center of the Solar System. It is so hot, the surface temperature of the Sun is over 5,770K degrees. This star is the most important energy source for life of Earth.

The sun is a 4.6 billion year old yellow-dwarf star. It is also 99.86% the mass of the solar system. The sun was created from the solar nebula which our solar system was also made from. The sun is so big that 1,300,000 Earths can fit in the sun.The sun is made up of mostly hydrogen and helium. Carbon dioxide, nitrogen, and oxygen make up 1.5%. The sun gets its energy from nuclear fusions in its core. The sun is half way through its life but it has enough energy to last 5 billion years more. Without the sun, life on Earth would not exist. Did you know that one day the sun will consume the Earth.

The Sun, a yellow dwarf star, is the heart of our solar system. Its gravity holds the solar system together and keeps everything in its orbit. Electric currents in the Sun generate a magnetic field carried out by the solar wind through the solar system - a stream of electrically charged gas blowing in all directions from the Sun.
