Unit 4 Climate Flashcard Review

Front

What is the characteristic of high latitudes in terms of solar energy received?

Back

High latitudes receive less solar energy.

Front

What is the role of the mesosphere in Earth's atmosphere?

Back

The mesosphere burns up meteoroids.

Front

What do greenhouse gases do in the atmosphere?

Back

Greenhouse gases absorb and radiate heat.

Front

What percentage of the atmosphere is made up of oxygen?

Back

Oxygen makes up approximately 20% of the gases in the atmosphere.

Front

In which ocean does an El Nino event occur when tropical ocean surface waters are warmer?

Back

An El Nino event occurs in the Pacific Ocean.

Front

Define low latitudes in terms of solar energy reception.

Back

Low latitudes receive more solar energy compared to high latitudes.

Front

What is the significance of the stratosphere in relation to the ozone layer?

Back

The stratosphere contains the ozone layer, which protects Earth from harmful UV radiation.

Front

How do human activities impact greenhouse gas concentrations?

Back

Human activities, such as burning fossil fuels, increase greenhouse gas concentrations in the atmosphere.

Front

What is the primary function of the troposphere?

Back

The troposphere is where weather occurs and contains most of the atmosphere's mass.

Front

What is the effect of El Nino on global weather patterns?

Back

El Nino can disrupt normal weather patterns, leading to increased rainfall in some areas and droughts in others.
