# AP Environmental Science : Atmospheric Movement and Patterns

## Example Questions

### Example Question #1 : Atmospheric Movement And Patterns

When talking about atmospheric circulation, what latitude range do the trade winds occupy?

to

to

to

to

to

to

Explanation:

Trade Winds are a result of hot air from the equator rising, cooling and then sinking and dispersing within the 30 N to 30 S range, with a range of 30 degrees on both sides of the equator.

### Example Question #1 : Atmospheric Movement And Patterns

Which terms best fits the following definition?

"The cyclical pattern of rising hot air, cooling of air, and sinking of colder air, resulting from exposure to sunlight (heat energy)."

Solar Wind

Atmospheric Circulation

The Greenhouse Effect

El Niño

La Niña

Atmospheric Circulation

Explanation:

Atmospheric circulation is the process in which air heated at a lower altitude rises because it is less dense than cold air, and the resulting cooling and dispersal/fall of the chilled air results in a natural circulation of air in the atmosphere.

### Example Question #11 : Atmosphere

Where in the atmosphere does weather occur?

Thermosphere

Mesosphere

Stratosphere

Troposphere

Troposphere

Explanation:

An easy way to know where the weather occurs in the atmosphere is to think of clouds. Since clouds are where precipitation originates and another form of a cloud can be low dwelling fog, you know that weather must appear close to the earths surface, and the lowest part of the atmosphere is the Troposphere.

### Example Question #1 : Atmospheric Movement And Patterns

In 1735, a scientist named George __________ hypothesized how air currents circulate and the mechanism that he discovered was named after him. His subsequent theory helps to describe the mechanics that cause air currents to rise at the equator and fall at the thirty degree latitudes?

Hardy-Weinberg cells

McLeod Cells

Janzen-Connell cells

Mason cells

Explanation:

The correct response is "Hadley." George Hadley developed the theory of the Hadley Cell. This is the only answer choice that referred to a scientist that studied atmospheric movements. Two of the answer choices have nothing to do with the atmosphere and they are general theories of ecology such as the Janzen-Connell hypothesis regarding biodiversity and the Hardy-Weinberg principle that is associated with genotype frequencies. Last, Mason and McLeod were fabricated for the sake of the question.

### Example Question #1 : Atmospheric Movement And Patterns

What is the Coriolis effect?

The global circulation of air due to patterns of heating and cooling of the air

The effect the Earth's rotation has on the movement of air and water in the atmosphere and oceans

The effect latitude has on global air movement

The effect of ocean currents on air movement

The effect of shifting air due to heating and then cooling as the air rises
