Seasons come to us regularly. We have probably
noticed that it gets warmer in summer or dry season while it get colder in the
winter or wet season. However do we know how these seasons change?
Seasons happen and change every year. This happens
because the earth tilts back and forth as it goes around the sun. During the summer,
the earth tilts toward the sun. It makes half of the earth hotter. this
condition is what we call summer. During the other half of the year, the earth
tilts away from the sun. As a result, it makes that half of the earth cooler.
This cool condition is then what we call winter.
The different parts of the world have the same
season at different times. In the northern half of the world , winter happens
during the months of December, January and February. The regions are such North
America and Europe. In the other hand, the southern half of the world have
winter during the months of June, July and August.The regions are like South
America and Australia. How does this difference happen? The same season happens
at different times because the top and bottom halves of the earth tilt away
from the sun at different times.
