This data suggests the Giant impact was at a low angle and NOT a direct impact.

• True

• False

Differences in ___________ caused the Earth and Moon to develop layers?

• Density

• Rotation

• Distance

What layer is present in the Moon but absent in Earth?

• Inner Core

• Mantle

• Partial Melt

• Crust

What is the thickest layer in both the Moon and the Earth?

• Inner Core

• Mantle

• Outer Core

• Crust

The clumping together of rocky material in space to form planets (and our moon), such as these salt crystals on the ISS, is called __________.

• Snowball Effect

• Aggregation

• Rotation

• Fusion

Rocks from the lunar surface have been radiometrically dated to be 4.5 billion years. The solar system and Earth formed between 4.5 to 4.6 billion years ago. This suggests that the moon formed _____________________________________.

• At the same time as the Earth was forming

• Before the Earth formed

• After the Earth formed

• It never formed, it's a conspiracy!
