Oceans

Front

What is upwelling?

Back

Upwelling is the process where cold, nutrient-rich water rises from the deep ocean to the surface, often supporting marine life.

Front

What causes surface waves in the ocean?

Back

Surface waves are primarily caused by wind.

Front

Where do cold ocean currents generally originate from?

Back

Cold ocean currents generally come from the North Pole and the South Pole.

Front

What is a result of upwelling in ocean water?

Back

A result of upwelling is an increase in nutrients in the water.

Front

What does the bulge of water on the side of the Earth closest to the moon produce?

Back

The bulge of water on the side of the Earth closest to the moon produces high tide.

Front

Define ocean currents.

Back

Ocean currents are large-scale movements of water within the world's oceans, driven by factors such as wind, temperature, salinity differences, and the Earth's rotation.

Front

What is the difference between high tide and low tide?

Back

High tide is the state of the tide when the water level is at its highest, while low tide is when the water level is at its lowest.

Front

What are the two main types of ocean currents?

Back

The two main types of ocean currents are surface currents and deep-water currents.

Front

What is the Coriolis effect?

Back

The Coriolis effect is the deflection of moving objects, such as ocean currents, due to the rotation of the Earth.

Front

What role do ocean currents play in climate?

Back

Ocean currents help regulate the Earth's climate by distributing heat from the equator to the poles.
