Moon's lunar poles have shifted over last 3 billion years, study finds

The video explains how a portion of the Moon's mantle melted, causing it to rise to the surface and form dark patches known as mare. This process led to a shift in the Moon's axis by 5.5 degrees, equivalent to a distance of 125 miles. The axis shift resulted in the Moon losing much of its ice deposits as they became exposed to the sun.

What geological feature on the Moon is formed by the melted mantle?

• Valleys

• Mare

• Mountains

• Craters

What caused the Moon's axis to shift by 5.5 degrees?

• Impact from an asteroid

• Lighter density of the melted surface

• Volcanic eruptions

• Gravitational pull from Earth

How far did the Moon's axis shift in miles?

• 300 miles

• 200 miles

• 125 miles

• 50 miles

What was one consequence of the Moon's axis shift?

• Increased volcanic activity

• Loss of ice deposits

• Formation of new craters

• Change in orbit

What happened to the Moon's ice deposits after the axis shift?

• They were exposed to the sun

• They increased in volume

• They moved to the poles

• They melted completely
