Unit 4: Ocean Currents and Climate Flashcard

Front

What are surface ocean currents?

Back

Surface ocean currents are movements of water that occur at the surface of the ocean, primarily driven by prevailing winds. They illustrate the transfer of energy from the atmosphere to the hydrosphere.

Front

Why does the equator experience consistent temperatures year-round?

Back

The equator experiences consistent temperatures year-round due to direct sunlight throughout the year, which provides a stable and high amount of solar energy.

Front

How do deep ocean currents compare to surface currents?

Back

Deep ocean currents are colder and denser compared to surface currents, which are generally warmer and less dense.

Front

What climate classification would location E likely have based on average yearly temperature and precipitation?

Back

Location E would most likely be classified as warm and dry.

Front

What effect does high albedo have on Earth's temperature?

Back

High albedo, such as that from light surfaces like ice and snow, decreases Earth's temperature by reflecting more sunlight.

Front

Define albedo in the context of climate science.

Back

Albedo is a measure of how much sunlight is reflected by a surface. High albedo surfaces reflect more sunlight, while low albedo surfaces absorb more.

Front

What role do ocean currents play in climate regulation?

Back

Ocean currents help regulate climate by distributing heat around the planet, influencing weather patterns and temperatures in different regions.

Front

Explain the term 'prevailing winds' and their significance in ocean currents.

Back

Prevailing winds are the dominant wind patterns in a region that drive the movement of surface ocean currents, affecting climate and weather.

Front

What is the relationship between ocean currents and weather patterns?

Back

Ocean currents influence weather patterns by transporting warm or cold water, which can affect air temperatures and precipitation in coastal areas.

Front

How does the temperature of ocean water affect marine life?

Back

The temperature of ocean water affects marine life by influencing species distribution, breeding cycles, and the overall health of marine ecosystems.
