What causes the earth to experience different seasons?
Have you ever wondered why the earth experiences Fall, Winter, Spring, and
Summer? Generally, the Northern Hemisphere will experience different climate
conditions than the Southern Hemisphere. For instance, one hemisphere will
experience the cold conditions of winter while the other hemisphere experiences
the warmer conditions of summer. This is illustrated in the picture at left
which shows the Northern Hemisphere countries of the U.S., Canada, and Mexico
experiencing the warm conditions of summer while the Southern Hemisphere
experiences the cooler conditions of winter. The image on the right shows the
reverse: the Northern Hemisphere is experiencing Winter while the Southern
Hemisphere experiences Summer.
Did you know that our four seasons exist because of the tilt of the earth on
its axis and because of the earth's orbit around the sun? The manner in which
this factor produces our seasons is very easy to explain. Take a few moments
to think about how this may occur.
