Moon Formation, Features, and Giant Impact Hypothesis

Which feature of the moon was formed by erupted lava.

• Craters

• Basins

• Highlands

• Maria

Which of these lunar features was not created when the Moon was impacted by other solid bodies

• Rays

• Craters

• Basins

• Rilles

Which two lunar features form together from the same event

• Rays

• Basins

• Craters

• Maria

Which two lunar features are related to each other as follows. One influenced the formation and resulting location of the other.

• Poles

• Craters

• Basins

• Maria

Which of these features of the Moon was not created during the heavy bombardment period?

• Regolith

• Craters

• Basins

• Maria

The lighter colored areas of the nearside of the Moon are:

• Highlands

• Rilles

• Basins

• Maria

Which feature may have formed by the cooling and shrinking of the moon?

• Highlands

• Rilles

• Basins

• Maria

How do basins and craters differ?

• Basins are much larger

• Craters are much larger

• Both form from impacts

• Craters are often filled with lava flows, basins are not

How are basins related to maria?

• Basins were formed when lava erupted from the moon violently.

• Basins and maria formed at the same time by large impactors.

• Maria have no relationship with lunar basins.

• Maria formed when lava erupted through the thin fractured crust of the basins.

What event may have caused the far side crust to have taller highlands?

• The collision of Earth's two moon's

• A prolonged period of volcanic eruptions in the farside

• A prolonged period of volcanic eruptions in the nearside

• The nearside was impacted more than the farside after the heavy bombardment period
