Oceans and Climate

Front

What happens to water when it is more dense?

Back

Water sinks.

Front

Which location is warmest when the sun is directly overhead?

Back

Location A is warmest.

Front

What are deep (density) currents?

Back

They are currents that move and mix water around the Earth, moving slower than surface currents and carrying cold water from the poles to the equator.

Front

What is the Coriolis effect?

Back

It is the effect that causes moving air and water to turn and twist rather than to move in a straight line.

Front

Where does cold air move on Earth?

Back

Cold air sinks towards the North and South Poles.

Front

What is the main cause of ocean currents?

Back

Differences in temperature and salinity.

Front

What are surface currents?

Back

They are currents that move water horizontally across the surface of the ocean, driven mainly by wind.

Front

What is the role of the sun in ocean temperature?

Back

The sun heats the surface of the ocean, affecting water temperature and currents.

Front

What is upwelling?

Back

Upwelling is the process where deep, cold water rises to the surface, bringing nutrients.

Front

What is the difference between weather and climate?

Back

Weather is the short-term atmospheric conditions, while climate is the long-term average of weather patterns.
