ESS.2.2 Notes Review

Front

How does temperature affect ocean currents?

Back

Cold water is dense and will sink. As the water warms up, it becomes less dense and will rise to the surface.

Front

What are the main factors that produce ocean currents?

Back

Ocean currents are produced by differences in the temperature of the water at different depths.

Front

What has the biggest effect on deep ocean currents?

Back

Temperature and salinity.

Front

What happens to warm water in the ocean?

Back

Warm water moves fast and is less dense, causing it to rise to the surface.

Front

What happens to cold water in the ocean?

Back

Cold water is dense and will sink.

Front

How do latitudes affect average temperatures?

Back

Locations with similar latitudes often have the same average temperatures, but some do not follow this pattern.

Front

Which two locations show the same latitude but different average temperatures?

Back

A and B.

Front

What is the relationship between ocean currents and climate?

Back

Ocean currents can influence climate by distributing heat around the planet.

Front

What role do salinity and temperature play in ocean currents?

Back

Salinity and temperature differences drive the movement of deep ocean currents.

Front

What is the significance of ocean currents in the Earth's system?

Back

Ocean currents help regulate climate, distribute nutrients, and support marine ecosystems.
