Explanation

The rotation of the Earth has several significant environmental effects. First, it creates a diurnal cycle of light and darkness, which directly influences daily rhythms in air temperature and humidity [3]. Second, the rotation generates the Coriolis force, which deflects the flow path of both atmospheric winds and ocean currents in a sideward direction—to the right in the Northern Hemisphere and to the left in the Southern Hemisphere [2]. Third, while tides are primarily caused by the gravitational pull of the Moon and Sun, the Earth's rotation is responsible for the regular, twice-daily rise and fall of sea levels (high and low tides) as different parts of the Earth rotate through the tidal bulges [3]. Therefore, all three statements correctly describe environmental consequences of the Earth's rotation.
