APES Unit 4 TRY to Mark Better! :)

Which latitude shown on the diagram above experiences 24 hours of daylight on December 21?

Antarctic Circle

At which of the following sites would activity result in volcanoes, island arcs, and mountains?

B

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

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

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

Desert

Earth currently rotates on an axis at an angle of 23.5 degrees. If that axis changed to 20 degrees, so that the axis was closer to vertical, which of the following would be expected to occur?

Earth would experience a change in seasonal timing and length.

Which of the following statements correctly explains the tectonic plate activity on the West Coast of the United States?

Earthquakes occur at the San Andreas Fault when stored energy is released from locked plates.

Region with the lowest atmospheric pressure

Exosphere (the top)

Review soil triangles technique

Right to left to down (makes 100)

Which "soil" has the greatest permeability?

Sand

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.

What happens to the tectonic plates along a transform boundary at the moment when an earthquake occurs

The grinding action between the plates at a transform plate boundary results in shallow earthquakes, large lateral displacement of rock, and a broad zone of crustal deformation.Feb

Reasons that human populations historically have settled in floodplains include which of the following?

The soil in the floodplains is usually fertile, the terrain in floodplains tend to be flat, floodplains are close to rivers for transportation

In the desert regions of the southwestern United States, daily high and low temperatures will frequently fluctuate by 40 F (33C) or more. Which statement below best explains the large variation in temperature?

There are no bordering oceans or large bodies of water to provide a stabilizing humidity to the air.

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

Troposphere

Brown pelicans are fish-eating birds. As a result of an El Niño event, the population of brown pelicans in southern California declines. Which of the following best explains the relationship between the El Niño event and the population decline?

Warmer ocean temperatures can cause fish to move to colder water farther from pelican nest sites

The primary cause of Earth's seasons is the

constant tilt of Earth's rotational axis with respect to the plane of its orbit around the Sun

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

descending dry air currents

Most volcanism in the world is associated with

plate boundaries
