What Causes the Four Seasons?
The
temperate deciduous forest has four changing seasons. These forests have
hot summers and cold winters. As the seasons change, so do the colors of
the leaves of the deciduous trees. Deciduous
means that these plants lose their leaves every year and grow them back.
Reasons for Seasons
The four seasons happen because of the tilt of the Earth's
axis. At different times of the year, the sun's rays hit different parts
of the globe more directly. The angle of the Earth's axis tilts the Northern
Hemisphere towards the sun during the summer.
Without
the tilt of the earth's axis, we wouldn't have seasons. Instead, the areas
around the equator would receive the most sun and the northern and southern
hemispheres would be stuck in a gradual gradient of hot to cold. The seasons
would not change, it would be about the same temperature year round and
there would be no seasons.
Is it true that the earth is
closer to the sun in winter?
Because of its elliptical orbit, the earth is closer
to the sun during the northern hemisphere's winter. However, distance from
the sun does not affect the seasons. The tilt of the earth's axis
causes the seasons to change.
