Which of the following is a biome found at 30°N and 30°S as seen in the diagram?

Deserts

Directions: Select the choice that best fits each statement. The following question(s) refer to the following regions of Earth's atmosphere. (A) Thermosphere (B) Exosphere (C) Troposphere (D) Mesosphere (E) Stratosphere The beneficial ozone layer is in this region of the atmosphere.

Stratosphere

Region where the protective ozone layer is located

Stratosphere

This layer of Earth's atmosphere contains the ozone layer that absorbs the sun's ultraviolet rays.

Stratosphere

Which of the following shows the approximate concentration of CO2, N2, and O2 in dry air?

CO2: <1% N2: 78% O2: 21%

Most of the Earth's deserts are at approximately 30° latitude, north and south, because these latitudes are characterized by

Descending dry air currents

Region with the lowest atmospheric pressure

Exosphere

Reasons that human populations historically have settled in floodplains include which of the following? I. The soil in floodplains is usually fertile. II. The terrain in floodplains tend to be flat. III. Floodplains are close to rivers for transportation.

I, II, and III

Which of the following correctly characterizes one of Earth's atmospheric layers?

Layer D is the thermosphere, where auroras are found.

A team at a university in Pennsylvania has concerns about the health of streams in a watershed because of the various land uses in the area. There has been an increase in road repair work, and the area has many dairy farms. Which of the following would be most effective at preventing sediment runoff into the streams of the watershed?

Maintain zones of grass at least 100m wide on the sides of streams in the area

Which of the following is the most abundant gas by volume in the atmosphere?

N2

Directions: Select the choice that best fits each statement. The following question(s) refer to the following elements. (A) Oxygen (B) Aluminum (C) Iron (D) Nitrogen (E) Argon The most abundant element in Earth's atmosphere

Nitrogen

The most abundant gas in Earth's atmosphere is

Nitrogen

Which of the following is the source of energy driving the circulation pattern labeled C in the diagram?

Solar radiation

Which of the following best describes why understanding a watershed and its boundaries is important in designing housing developments along a river?

Surface water and stormwater runoff will drain downstream within the watershed boundaries, so it is important to understand the flow of water through the watershed.

Hoover Dam is the largest dam in the United States, built on the Colorado River to supply hydroelectric power and flood control. Which of the following best describes a downstream environmental effect of Hoover Dam on the Colorado River watershed?

The damming of the Colorado River led to a change in stream flow, preventing river water and sediments from reaching the delta area.

Which of the following should be included in a watershed map to best determine the non-point source of a pollutant, such as fertilizer, found in a river?

The land use upstream of the river and water quality indicators in streams that run downstream into the river

Based on the diagram, which of the following identifies a characteristic of the atmosphere between the stratopause and the tropopause?

The ozone layer is in the stratosphere

Which of the following best explains why the lower portion of the troposphere is warmer than the upper portion?

The surface of Earth absorbs sunlight, heating the lower portion of the troposphere more than the upper part.

Based on the data in the diagrams, in which layer of the atmosphere would short wave radio signals be reflected?

Thermosphere

This layer of Earth's atmosphere contains the fewest molecules of the layers shown, and the low density of gas leads to very few molecules transferring heat to an object. In this layer, ultraviolet radiation causes photodissociation of molecules, creating ions.

Thermosphere

This layer of Earth's atmosphere has the highest density of any atmospheric layer and contains most of the water vapor in the atmosphere.

Troposhere

Directions: Select the choice that best fits each statement. The following question(s) refer to the following regions of Earth's atmosphere. (A) Thermosphere (B) Exosphere (C) Troposphere (D) Mesosphere (E) Stratosphere Most oxygen is found in this layer of the atmosphere.

Troposphere

Directions: Select the choice that best fits each statement. The following question(s) refer to the following regions of Earth's atmosphere. (A) Thermosphere (B) Exosphere (C) Troposphere (D) Mesosphere (E) Stratosphere The phenomenon causing global warming occurs primarily in this region of the atmosphere.

Troposphere

In which of the following atmospheric layers does most weather occur?

Troposphere

Region largely responsible for the weather experienced at the Earth's surface

Troposphere

Region that contains the majority of molecules in the atmosphere

Troposphere

Most deserts on Earth are located near the 30° north and 30° south latitudes because humidity is lower at 30°. The best explanation for the lower humidity is that

Warm air rises at the equator, cools, and sinks at 30° latitude

Which of the following causes the air to rise high into the atmosphere in the areas labeled A, B, and C on the diagram?

Warm, moist air that is less dense than the surrounding air
