The Seasons

Every country on Earth experiences Day and Night. We also know some countries on experience different seasons, some experience the dry and raining seasons and some experience Spring, Summer, Autumn and Winter.

Now, one will ask where from the different seasons?

Scientists explain that a meteoroid collision with the earth disoriented its axis of spin by about 23.5 degrees. This resulted in different seasons due to differences in the intensity of the sun experienced at different sections of the earth for certain periods. We experience day and night which occurs within a twenty-four hour period because the earth spins around its axis. The earth continually spins around its axis because of the principle of conservation of momentum.

In simple terms, the initial spin (angular momentum) of the gases that came together to form the earth is what keeps the earth spinning.
