The document discusses the phases of the Moon and how they occur. It explains that the Moon orbits Earth and the portion we see illuminated changes throughout the month in a cycle. The four main phases are the new Moon, first quarter, last quarter, and full Moon. The Moon appears to change shape because as it revolves around Earth, different portions of the side facing Earth are illuminated by the Sun. The Moon itself does not actually change shape.

9. How are Earth and the Moon Different?
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.

is a hollow area or
pit in the ground.
• Most craters on
• 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.
