What causes the seasons? explain. be as precise and accurate as possible.

Rotation of the earth on its axis.

Explanation:

The earth is tilted at 23.5 degrees relative to its ecliptic plane and rotates in an anticlockwise direction around the sun this causes the winds in the earth to move from left to right in the northern hemisphere and in right to left in southern hemisphere knowns the Coriolis effect. The impact of sun rays creates a system n the earth's landscape that makes the earth produce temperature inversions and relative earth has three pressure cells that move in a cyclic order from the equator to the poles. It is also due to the angle of inclination around the sun that the earth experience cold and warm weather in summers as a result of the tilt the sun rays fall directly 90 degrees on the equator and are inclined toward the poles at the angle of 30 degrees.  Also, the presence of upper air jet streams and geostrophic winds influence the temperature ranges o the earth they bing in the warm and cold air masses from the other regions and equator being a region of mixing diverts all of these winds hence creating a good balance.

The figure is not necessarily a parallelogram because only one diagonal is bisected and only one pair of sides is congruent.
