The Moon!

What is the gravity of the moon like compared to Earth?

• It has half the Earth's gravity.

• It has 1/6th the Earth's gravity.

• It has 3x the Earth's gravity.

• There is no gravity on the moon.

Which rock type is mainly found on the moon?

• Igneous

• Metamorphic

• Sedimentary

• MIneral

The name of the theory that states the moon was formed when Earth was hit with a Mars-sized object, and material was ejected and condensed is (a)  

Which land form was thought by Galileo to be seas on the moon?

• Rilles

• Craters

• Maria

• Apollo

Which of these is NOT an important impact of the moon?

• It keeps the Earth from wobbling and changing our climate zones.

• It is the main cause of the tides and the intertidal zone.

• It provides some light on the evenings that the moon is visible (ex: full moon).

• It keeps the Earth orbiting the sun.

Why does the moon have some many craters?

• It has no atmosphere, so it has no weathering or erosion.

• The lack of atmosphere means meteors/asteroids don't burn up, so more hit the moon.

• A and B

• None of the above.

Why do we have moon phases?

• Because sometimes the moon is closer and sometimes it is further from Earth.

• Because we see different amounts of the lighted side of the moon.

• Because the moon changes phases as the night goes on.

• Because it is sometimes blocked by the Earth.

Which statements are true about rocks on the moon? Check all that apply.

• We don't find metamorphic rocks on the moon because there are no plate tectonics.

• We don't find sedimentary rocks on the moon, because there is no water, weathering, or erosion.

• We find sedimentary rocks on the moon because of all the maria or seas.

• The rocks on the moon are mainly igneous because it is made from material that was once molten.

The moon has layers inside it, similar to Earth's structure.

• True

• False

The near and far side of the moon are different from each other- the far side has more craters and the crust is thicker.

• True

• False
