Honors Oceanography Unit 5 Test Review

Front

Why does warm air rise?

Back

Warm air is less dense than cooler air.

Front

What is the name of the current labelled A in the figure?

Back

Alaska Current

Front

What is the large, circular pattern formed by 4 surface currents found in each ocean called?

Back

Gyre

Front

What is the name of the current labelled B in the figure?

Back

Antilles Current

Front

What causes El Niño in the Pacific Ocean?

Back

An interruption of flow of the Humboldt and Equatorial Currents.

Front

Define 'density' in the context of air and water.

Back

Density is the mass of a substance per unit volume, affecting buoyancy and movement.

Front

What are surface currents and how do they form?

Back

Surface currents are horizontal water movements caused by wind, Earth's rotation, and temperature differences.

Front

Explain the significance of gyres in ocean circulation.

Back

Gyres help distribute heat and nutrients across the oceans, influencing climate and marine ecosystems.

Front

What role do the Humboldt and Equatorial Currents play in oceanic conditions?

Back

They influence weather patterns and marine life, particularly during El Niño events.

Front

How does the Coriolis effect influence ocean currents?

Back

The Coriolis effect causes currents to curve due to Earth's rotation, affecting their direction and speed.
