Contrast spring and neap tides and their causes.
Spring tides occur during new and full moons, while neap tides occur during the first and third quarters of the moon.
Spring tides occur during the first and third quarters of the moon, while neap tides occur during new and full moons.
Spring tides and neap tides occur at the same time and have the same causes.
Spring tides occur only in spring, while neap tides occur only in autumn.
Define upwelling and explain its importance.
Upwelling is the process where deep, cold, and nutrient-rich water rises to the surface, supporting marine life and fisheries.
Upwelling is the movement of warm surface water to the deep ocean, reducing marine biodiversity.
Upwelling is the process of ocean water evaporating, leading to increased salinity.
Upwelling is the phenomenon of ocean currents moving parallel to the coast, causing erosion.
