Science Review: Oceanography

Front

What is the continental shelf?

Back

The continental shelf is the part of the ocean floor that is close to the shore and is relatively shallow compared to the deeper parts of the ocean.

Front

What are ocean currents?

Back

Ocean currents are large streams of water that flow through the ocean in circular motions, affecting climate and marine life.

Front

What causes tides in the ocean?

Back

Tides are caused by the gravitational pull of the moon and the sun on the Earth's oceans.

Front

What is the difference between waves and currents?

Back

Waves are the surface movement of water caused by wind, while currents are continuous, directed movements of water in the ocean.

Front

What is an abyssal plain?

Back

An abyssal plain is a flat, deep part of the ocean floor that is found at depths of 3,000 to 6,000 meters.

Front

What is the continental slope?

Back

The continental slope is the steeply sloping area between the continental shelf and the deep ocean floor.

Front

What is the role of the sun in ocean tides?

Back

The sun's gravitational pull also affects tides, but its effect is less than that of the moon.

Front

What is the temperature trend in the ocean as depth increases?

Back

As depth increases, the temperature of the ocean generally decreases.

Front

What are waves?

Back

Waves are movements of water that are created by wind blowing across the surface of the ocean.

Front

What is the continental rise?

Back

The continental rise is the area at the base of the continental slope where sediments accumulate.
