Which of the lettered choices in the soil profile above represents the region with the greatest concentration of organic material?

A

Which of the following would be the best control sample for the study

A sample of water collected downstream from northern forest

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

B

At which of the following sites is an earthquake most likely to occur as two plates slide sideways past each other?

C

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

CO2 < 1% N2 78% O2 21%

Which of the following is the correct order of soil particles in order of increasing size?

Clay, Silt, Sand

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

E

Region with the lowest atmospheric pressure

Exosphere

Which of the following best explains why the shaded area receives more snowfall than the other parts of New York, Pennsylvania, and Ohio?

Moisture picked up from the warmer water in the great Lakes is deposited as snow downwind.

Which of the following properties of the soil sample most influences the flow of water through the sample?

Permeability

Sample D

Of the following, which has the greatest permeability?

Sand

During an El nino-southern oscillation event, which of the following best describes conditions in the eastern part of the tropical pacific ocean

Sea surface temp rainfall high

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

Solar radiation

The beneficial ozone layer is in this region of the atmosphere

Stratosphere

Which of the following best describes why understanding a watershed and its boundaries is important in designing housing development 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

Which of the following correctly describes the season and length of day at the tropic of cancer at the time of year shown in the diagram?

The Northern hemisphere is tilted away from the sun so it is winter at tropic of cancer and daylight is less than 12 hours per day

Which of the following is the dependent variable in the study?

The density of species of algae growing along the bottom of the river

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 not the river

If the diagram illustrates Earth's relative position on December 21 of a given year, which of the following statements would be correct?

The tropic of Cancer has a shorter day and lower solar radiation intensity because there is a direct relationship between day length and radiation intensity

Which of the following areas receives the most intense solar radiation at the time of year shown in the diagram, and why?

The tropic of capricorn, because this latitude is nearly horizontal to incoming solar radiation

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

Troposhere

Which of the following explains the variable that would be best for students to measure to determine the direct impact of soil erosion caused by the construction project on the river?

Turbidity

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

Which of the following is the most likely effect of a strong El Nino event on the weather patterns in the US

Wetter weather and cooler than average temps in the southeastern states and warmer temps in the pacific northwest

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 earths deserts are at approximately 30 degrees latitude, north and south, because these latitudes are characterized by

descending dry air currents

Most deserts on Earth are located near the 30 degrees N and 30 degrees S latitude because humidity is lower at 30 degrees. The best explanation for the lower humidity is that

warm air rises at the equator, cools, and sinks at 30 degrees latitude
