2. Earth and Moon Comparison

3. How the Earth and Moon are the Same

4. The Earth and the Moon are the same in many ways: Both are made of some of the same materials (iron, aluminum, calcium, and silicon) Both are made of some of the same materials (iron, aluminum, calcium, and silicon)

5. Both Have a Gravitational Pull The pull of gravity holds a smaller object in its orbit. The pull of gravity holds a smaller object in its orbit. The Moon is in orbit around the Earth and the Earth is in orbit around the Sun. The Moon is in orbit around the Earth and the Earth is in orbit around the Sun.

6. The Earth and the Moon are the same in many ways: Barringer Meteor Crater, Arizona The moon has many more craters than the Earth! They both have craters. They both have craters.

7. Most of the craters on the Earth have been affected by weathering and erosion so they are harder to see. Most of the craters on the Earth have been affected by weathering and erosion so they are harder to see. The Manicouagan Crater in northern Canada is one of the oldest impact craters known. The crater itself has been worn away by the passing of glaciers and other erosional processes.Manicouagan Crater Wolfe Creek is a relatively well-preserved crater that is partly buried under wind blown sand. The crater is situated in the flat desert plains of north-central Australia.

8. Since there is no weather or liquid water on the moon to cause erosion of landforms, craters and other things that impact the surface can last for millions of years. Since there is no weather or liquid water on the moon to cause erosion of landforms, craters and other things that impact the surface can last for millions of years.

9. They have other landforms that are the same, too: They have other landforms that are the same, too: The Earth and the Moon are the same in many ways: Plains (called mare on the moon) Valleys (called rilles on the moon) Mountains (called highlands on the moon)

10. Plains Valleys Mountains

11. Both the moon and the Earth have a history of volcanic eruptions. The surface of the moon is covered in mare. These appear to be seas of water, but are actually the cooled lava (basalt) that have filled craters on the moon. The Earth still has active volcanoes, but the moon does not.

12. The Earth and the Moon are the same in many ways: They both rotate on their axis. They both rotate on their axis. The moon rotates at 10 miles an hour. The Earth rotates at 1,000 miles an hour!

13. The Earth and the Moon are the same in many ways: They both revolve around another object. They both revolve around another object. The Earth revolves around the Sun.The Earth revolves around the Sun. The Moon revolves around the Earth.The Moon revolves around the Earth.

14. How the Earth and Moon are Different

15. The Earth and the Moon are different in many ways: The moon does not have these landforms: The moon does not have these landforms: Oceans Rivers Marshes Glaciers Beaches Remember, the moon does not have any liquid water so it could not have any of these landforms!

16. The Earth and the Moon are different in many ways: The Earth has wind. It is caused by the uneven heating of the air and water. The moon has no wind because it has no liquid water and no atmosphere! The Earth has wind. It is caused by the uneven heating of the air and water. The moon has no wind because it has no liquid water and no atmosphere!

17. The Earth and the Moon are different in many ways: The pull of gravity is also different on the moon and the Earth. The moon’s pull of gravity is 1/6 th of the Earth’s pull of gravity! The pull of gravity is also different on the moon and the Earth. The moon’s pull of gravity is 1/6 th of the Earth’s pull of gravity! Earth Weight: 102 pounds Moon Weight: 17 pounds

18. The Earth and the Moon are different in many ways: Since the moon has no atmosphere, there are also no plants, animals, or liquid water on the moon! Since the moon has no atmosphere, there are also no plants, animals, or liquid water on the moon!

19. The Earth and the Moon are different in many ways: Their revolution also takes different amounts of time. Their revolution also takes different amounts of time. The moon’s revolution takes approximately 28 days. The Earth’s revolution takes 365 ¼ days (or one year)!

20. EarthMoon Use the Venn Diagram to compare the physical characteristics of the Earth and Moon.

21. Earth Moon water crust volcanoes erosion no water earthquakes surface has hardly changed in 3 billion years. surface changes daily Let’s check how you did. gravity

22. Why is the Sun important to both the Earth and Moon? The Sun gives light and heat to the Earth. The Sun gives light and heat to the Earth. Without the Sun we would have no water cycle. Without the Sun we would have no water cycle. The Sun helps plants make food in the process of photosynthesis. The Sun helps plants make food in the process of photosynthesis. The Sun gives light to the Moon. The Sun gives light to the Moon.

23. Quiz Time!

24. Which of the following BEST explains why there are more craters on the moon than on the earth? A. Earth has an atmosphere. B. The moon is smaller than the earth. C. Earth has rarely been struck by meteors. D. The moon has a weaker gravitational force.

25. A student is going to create a model of the size of the moon compared to the Earth. Which two items would be the best representation of their sizes? A. A marble to represent both the Earth and the moon. B. A tennis ball to represent the moon and a marble to represent the Earth. C. A tennis ball to represent both the Earth and the moon. D. A tennis ball to represent the Earth and a marble to represent the moon.

26. Which of the following are found on the Earth and the moon? A. Earthquakes B. Volcanoes C. Water D. Erosion

27. Neil Armstrong was the first person to walk on the moon. If we traveled to the moon today, we could still see his footprint as it was when he made it in 1969.

28. Using what you have learned about the moon, why would Neil Armstrong’s footprint last on the moon for millions of years but footprints on a beach may only last for hours? Using what you have learned about the moon, why would Neil Armstrong’s footprint last on the moon for millions of years but footprints on a beach may only last for hours?
