24 Ocean Topography, Currents, Waves Review

What is the continental shelf?

Back

The continental shelf is the underwater land that extends from the coastline to the continental slope, characterized by shallow waters.

Front

What is the Coriolis Effect?

Back

The Coriolis Effect is the deflection of moving objects, such as air and water, caused by the rotation of the Earth, resulting in clockwise movement in the Northern Hemisphere and counterclockwise in the Southern Hemisphere.

What happens to water temperature and salinity when it sinks?

Back

Cold and salty water sinks faster than warm and fresh water due to its higher density.

Front

What is the continental slope?

Back

The continental slope is the steep drop-off between the continental shelf and the deep ocean floor.

Front

How do ocean currents form?

Back

Ocean currents are formed by wind, the Earth's rotation, and differences in water temperature and salinity.

What is upwelling?

Back

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

What is the difference between waves and currents?

Back

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

What role does temperature play in ocean water density?

Back

Colder water is denser than warmer water, which affects how water layers interact and move.

What is the significance of the ocean's thermohaline circulation?

Back

Thermohaline circulation is a global system of ocean currents driven by temperature and salinity differences, crucial for regulating climate.

What are tides?

Back

Tides are the regular rise and fall of sea levels caused by the gravitational pull of the moon and the sun.
