1. Creating the cycle of day and night, leading to diurnal variations in sunlight and thus air temperature (daily rhythm).
2. Causing the Coriolis effect, which deflects moving objects (like air and water currents) to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This influences wind patterns, ocean currents, and even the flow of rivers over long distances.
The movement of tides is primarily caused by the gravitational pull of the Moon and the Sun. While Earth’s rotation influences the timing and frequency of tides experienced at a particular location, the tidal bulges themselves are a result of gravitational forces, not Earth’s rotation directly causing the water movement as its primary effect in this context.
– Rotation causes the Coriolis effect, deflecting air and water flows.
– Tides are primarily caused by gravitational forces from the Moon and Sun.
