Moon Earth
1-sphere
2-Rotate
3-Revolve
4-Receive
light
from Sun
1-Day lasts 27 Earth
days.
2-about ¼ size of Earth
3-has less mass
4-has less gravity
5-craters cover most of
Its surface
6-has no water, no air,
no life.
1-Day lasts 24 hours.
2-has few craters.
3-Water is found in
many places.
4-Air is found, so Earth
supports life.

The Moon
is a hollow area or
pit in the ground.

• The moon have
• Formed by volcanoes.
• Some of them caused by chunks
of rocks or metals from space
that crashed into the Moon’s
surface.
• Some craters are very large and
some are quite small.

11. Ch.8 Lesson 5
Phases of
The Moon
• Earth has few craters??
• Most objects from space burn
up before they reach Earth.
• Also the air and water on Earth
cause craters to erode.
* If your weight on Earth 66 kg
• Your weight on the Moon only 11
kg ??
• Because the Moon has less mass
and less gravity.
