Earth, Sun, and Moon Notes
The Earth is the 3rd planet from the Sun. It supports life because it has water
and oxygen. It has a protective atmosphere that blocks out most of the Sun’s
damaging rays and protects it from small objects floating in space. It is made
mostly of rock.
The Moon revolves around Earth (it is a satellite of Earth). It is 240,000 miles
away and is ¼ the size of Earth. There is NO atmosphere. It has no air, wind or
liquid water. It reflects the light of the Sun.
The Sun is made of hot, glowing gases. It is about 93 million miles away.
EARTH’S ROTATION
Rotation = A single complete turn
The Earth rotates on an imaginary line called an axis, which runs through Earth
from the North Pole to the South Pole.
The rotation of the Earth causes day and night. One complete rotation of the
Earth takes 24 hours or 1 day As it rotates, one side of Earth faces the sun.
This side has daytime. The side of Earth facing away from the sun has nighttime.
