1. The Moon and Earth By: Riley, Emily, and Logan Miss. Wilson’s class

2. THE MOON (A moon is any natural body that revolves around a planet)

3. Size The moon is only ¼ the size of the Earth If you put them next to each other, they’d look like a basketball next to a tennis ball The moon is 3,474 km in diameter

4. Landforms & Craters The moon has mountains, valleys,soil, rocks, and dust If you were standing in a crater, you wouldn’t be able to tell that you were in one – they’re so big! The moon has so many craters because it doesn’t have an atmosphere to protect it

5. Gravity The moon has 1/6 gravity Gravity depends on 2 things: #1- the size #2- distance between objects

6. Weather & Atmosphere The moon has no atmosphere Because it doesn’t have an atmosphere, it has no weather The moon does have ice

7. Water The moon has little water, about 25 gallons Only recently scientists made the discovery of the little bit of water

8. Weathering & Erosion There is no weathering on the moon because there is no rain, wind, or water to do the erosion.

9. Time to rotate on its axis It takes 27 days to rotate once on its axis In 29 ½ days it will go around the earth once

10. EARTH

11. Size The Earth is 12,756 km in diameter It is the 5 th largest planet in our solar system

12. Landforms & Craters The Earth has craters, but not many The earth doesn’t have many because it has an atmosphere to protect it. Usually, it will burn up when it hits our atmosphere Some landforms on earth are: mountains, valleys, plains, etc.

13. Gravity Earth’s gravity is 6 times larger than the moon’s The Earth applies to the 2 gravity rules: It is large in size (compared to the moon) It is far from the moon

14. Weather & Atmosphere Unlike the moon the earth has an atmosphere It is made of 21% oxygen, 78% nitrogen, 9% argon, and 3% carbon dioxide with very small percentages of other elements Weather we have on Earth is: rain, snow, sleet, thunder/lightning, wind storms, etc.

15. Water The Earth is made up of 75% of water. That is more than half! There is very little fresh water on the Earth; there is mostly salt water

16. The earth has many kinds of weathering and erosion: Water Ice Wind And more!!!! Weathering & Erosion

17. MORE INFORMATION

18. Tides Tides are the gravitational pull of the moon on the Earth’s ocean Every day there is 2 tides: low tide, and high tide.

19. Mars Mars is Earth’s closest friend It is 6,792 km in diameter Because Mars is our closest planet, we think of aliens being on Mars more than any planet. That is where we get the name “Martians”
