How
do seasons happen?
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.
