The Seasons
The movement of Earth around the sun and the tilt of Earth
are the two reasons why we have seasons. As Earth orbits
the sun, the North Pole is tilted toward the sun for part of
the year. It is tilted away ’ from the sun for part of the year.
When the North Pole is tilted toward the sun, the a northern
part of Earth has long days and short A nights. It is summer
in the Northern Hemisphere, the a part of Earth above the
equator. .
When’ the North Pole is tilted away from the sun, the part of
Earth above the equator has short days and long nights. It is
winter in the Northern Hemisphere. Since the South Pole is
1
now closer to sun it is summer there!
There are two seasons when Earth's axis is not .tilted
toward or away from sun. This is when we have spring and
autumn. During spring and autumn, days and nights have
about the same number of hours.
