What causes water currents?

What causes water currents in the ocean?

Water currents are primarily caused by wind, the Earth's rotation, and differences in water temperature and salinity.

Can you explain how the Earth's rotation affects these currents?

Sure! The Earth's rotation causes the Coriolis effect, which deflects moving water to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

What role does temperature play in creating currents?

Temperature differences create density variations in water, leading to convection currents as warmer, lighter water rises and cooler, denser water sinks.

Are there any other factors that influence water currents?

Yes, factors like the shape of the coastline, the ocean floor topography, and even human activities can influence water currents.
