ES unit 5 Atmospheric Science Flashcard

Front

What are the 6 major convection currents found on Earth?

Back

Hadley Cell, Ferrel Cell, Polar Cell, Walker Circulation, El Niño, La Niña

Front

Which air circulation cell is found from 0 to 30 degrees North latitude?

Back

Hadley cell

Front

What is the largest reservoir for nitrogen in the atmosphere?

Back

The atmosphere is the largest reservoir for nitrogen.

Front

Which layer of the atmosphere contains the ozone layer?

Back

Stratosphere

Front

What is the correct order of the layers of the atmosphere moving from the Earth upwards?

Back

Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere

Front

Define Hadley Cell.

Back

A large-scale atmospheric convection cell that is located between the equator and 30 degrees latitude, where warm air rises and cool air sinks.

Front

What is the role of the Ferrel Cell in atmospheric circulation?

Back

The Ferrel Cell is a mid-latitude cell that helps to transport warm air poleward and cold air equatorward.

Front

Explain the significance of the Polar Cell.

Back

The Polar Cell is a convection cell that occurs at the poles, where cold air sinks and creates high-pressure areas.

Front

What is El Niño?

Back

El Niño is a climate pattern characterized by the warming of ocean surface temperatures in the central and eastern tropical Pacific Ocean.

Front

What is La Niña?

Back

La Niña is a climate pattern that describes the cooling of ocean surface temperatures in the central and eastern tropical Pacific Ocean.
