2. How does earth support life? Earth is the only planet in the solar system that has water on its surface. Water has a chemical that does not mach up with any other liquid. Water has a great ability to absorb heat, oceans store most of the heat the earth gets from the sun. The water ability makes it easer to brake down rocks.

3. How does the earth support life? • The ground and air is not to hot because the water on the earths surface keeps the air and ground the right tempter. The suns energy provides the right tempter for plants to grow the animals eat the plants and we eat the animals that provides energy for us to live.

4. How does the suns gravity support earth The earth is just the right distance from the sun. If the earth was to close to the sun it would be hot and windy. It would be windy because the earth would be spinning to fast. The water would get to hot and boil and the water would evaporate in to space. If the earth was to far from the sun the water would freeze. The suns gravity is strong enough to keep the earth orbiting the sun.

5. How dose the suns gravity support earth If the suns gravity was not strong enough the earth would float of into space. At this point the temperature would drop and we would die.

6. How was the earth formed Once the sun, and all the planets, in the solar system were nothing but cold dust particles swirling around in empty space. These partials came together to make a big spinning disk. As it spun the disk separated into rings. The center of the disk became the sun. The outer part if the disk became the planets in the solar system. The center of the disc was a hot fiery ball. The outer part of the disc became gas and liquid and it sat for billions of years then they came together and formed a planet that was the start of our solar system.
