2. Day and Night – page 2
The Earth’s ROTATION on its own axis causes the change of ‘day’ and ‘night’.
The Earth rotates on its axis once every 24 hours approximately.
The rotation of the Earth is WEST to EAST , so the Sun is visible in the eastern sky first.
The Sun shines only on HALF of the Earth at any time, so that half of the Earth is in daylight and the other half is in NIGHT.

3. Day and Night – page 2
The tilt on the Earth’s axis causes ‘day’ and ‘night’ to be of different lengths in different parts of the world.
The autumn and spring EQUINOXES occur twice (2 times) year when the day and night are of EQUAL length.

4. Seasons – page 2 Write down these dates at the top of page 2!
There are four distinct seasons
Winter-December 22nd Spring- March 21st
Summer-June 21st Autumn(fall)-September 23rd

6. Seasons – page 2
Seasons are caused by the Earth’s revolution around the Sun and the unchanging tilt of the Earth’s axis.
The different distances to the Sun caused by the tilt AND REVOLUTION cause seasons.
The season depends on how much of the Earth’s surface is covered by light rays, and at what angle they reach the Earth’s surface. Head-on rays on a small area are strong and cause LONG seasons. Slanting rays focusing on a large area are weaker and cause SHORT seasons.
