Investigations 3-4-5 Test

What are the dark/gray smooth regions of the Moon called?

• highlands

• craters

• maria

• highlands

Why do maria look smoother and have a darker color than other regions of the Moon?

• there are more minerals in that region

• magma filled in the region

• maria are made of many dark crystals

• the meteoroids that formed the craters were darker in color

How do rays form around craters?

• lava flowing from the crater

• minerals crystallizing after the impact

• matter ejected outward from the impact

• frozen water forming around crater

How many days does it take the Moon to orbit Earth?

• about 1 year

• about 1 month

• about 1 week

• about 1 day

The Moon has a day and night just like Earth.

• True

• False

Why do we see the same side of the Moon from Earth?

• The rate of the Moon's rotation and revolution speed is the same

• The Moon doesn't rotate on an axis

• The rate of the Moon's revolution around Earth is extremely fast

• The rate of the Moon's rotation is faster than Earth's rotation

Why do craters remain on the Moon and never get "erased?"

• The Moon doesn't have weather for erosion to occur

• It rains very little on the Moon

• The Moon's atmosphere protects the craters

• The craters get baked into the surface by the Sun's heat

The far side of the Moon does not receive the sun's light.

• True

• False

Why does the Moon's shape appear to change in a repeating cycle when viewed from Earth?

• the amount of lighted moon we see depends on the rate of its revolution

• the amount of lighted moon we see depends on the rate of its rotation

• the amount of lighted moon we see depends on how far the Sun's rays travel

• the amount of lighted Moon we see depends on the speed of Earth's revolution around the Sun

How old is the Moon?

• 4 thousand years old

• 4 million years old

• 4 billion years old

• 4 hundred years old
