Mo12-L3a: How Does the Moon Move?

Eventually, the material in the ring cooled and The Moon’s Motion
clumped together and formed the Moon.
The Moon rotates as it revolves around Earth.

One complete rotation of the Moon takes 27.3 days,
meaning the Moon makes one rotation in the same
amount of time that it makes one revolution around
Earth.

The surface of the Moon was shaped early in its
history.

Moon’s craters were formed when objects from
space crashed into the Moon.

Key Concept

How Does the Moon Move?
What produces the Moon’s revolution around
Earth?

The large, dark, f at areas on the Moon are called

SUMMARY

How Does the Moon Move?

According to the giant impact hypothesis,
a large object collided with Earth about 4.5
billion years ago to form the Moon.
Maria(plural), Mare (Singular)
Terra or Highlands

When the maria formed, lava f owed up through the
Moon’s crust and solidif ed, covering many of the
Moon’s craters and other features.
Features like maria, craters, and highlands
The light-colored highlands are too high for the lava formed on the Moon’s surface early in its
that formed the maria to reach. history.
