This is the Earth Room CREATED BY : Callie Harper This project is about the Earth and I hope you find this informational as well as fun because I had fun making it.
This is revolution. It takes 365 days to create one full revolution.
This is rotation. It takes 24 hours , or 1 full day , to complete.
The earth is the only planet , that we know of so far , that can support life. It is made up of rock and water. 75% or earth is water and the last 25% is land. Earth is the 3rd planet from the sun and has an atmosphere to keep meteors and asteroids away. It has a good enough gravitational pull to keep us on the ground
The moon is earths only natural satellite that is 1/4 size of the earth and has lots of craters formed by asteroids and meteors. The moon has such a low atmosphere it gets hit by asteroids and meteors. It has an ice ocean that's called the Maria The moon gets so hot in the day but so cold in the night!
The sun is the milky ways only star. It can produce its own light and heat. The sun is not a planet, it is a giant ball of hot gas. Even though it looks to be on fire it is not. The sun has sunspots, solar flares , and corona. Without the sun, we would all be ice cubes. It is in the center of our solar system.
There are two BIG words that you need to know.... rotation and revolution. Rotation is a 24 hour base causing the apparent movement of the sun causing day and night. Revolution is the Earth traveling around the sun. It takes 365 days to complete 1 full revolution around the sun or 365 rotations. Rotation takes less time to complete. By the time earth completes 1 full revolution, it has had 365 rotations. Earth does all the work while the center of attention does nothing. I think that's not fair.
Earth rotates on its axis causing day and night. Both rotation and revolution are happing at the same time. The sun looks like it is moving, but is it really? We , along with the other planets, orbit around the sun ,our ONLY natural light source. Earth is tilted as it goes around the sun and STAYS tilted. That causes our seasons, summer, spring, autumn and winter.
