how does the rotation of the Earth around the axis bring about changes in the climate resulting in the 4 seasons? and why do the countries at the equator not experience seasonel changes?

The rotation of the earth around its axis causes day and night. As the earth rotates, different parts of the planet are exposed to the sun's light, creating day and night cycles. This rotation means that the sun appears to rise in the east and set in the west, giving us the appearance of the sun moving across the sky.
The tilt of the earth's axis is responsible for the changing seasons. As the earth orbits around the sun, the tilt of its axis causes different parts of the planet to be tilted towards or away from the sun at different times of the year. This tilt affects the amount of sunlight and heat that reaches different parts of the earth, creating the four seasons.
The rotation of the earth plays a crucial role in the formation of winds and ocean currents. As the earth rotates, air and water are deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere due to the Coriolis effect. This deflection creates wind patterns and ocean currents that help distribute heat and moisture around the planet.
Yes, the rotation of the earth does affect gravity. The centripetal force created by the earth's rotation causes the planet to bulge slightly at the equator, making it farther away from the center of the earth. This leads to a slightly weaker gravitational pull at the equator compared to the poles. However, this difference is very small and does not significantly affect our daily lives.
The rotation of the earth is what determines the length of a day. As the earth rotates, it completes one full rotation in approximately 24 hours, giving us a 24-hour day. However, due to factors such as the moon's gravitational pull and the earth's own rotation slowing down over time, the length of a day has changed throughout history and continues to change by a fraction of a second each year.
