umm apes review unit 4
This area is most susceptible to erosion, leading to increased suspended solids and increased turbidity downstream.
B (AGRICULTURAL FIELDS)
Area that exhibits a growing nonvolcanic mountain chain due to uplift
C
Students want to determine the impact of soil erosion from the development of new housing. They plan to measure the density of a species of algae growing along the bottom of a river that flows through their town. The town is built in a heavily forested area, but a large area of trees along the river was recently clear-cut to allow for the construction of a new housing development, which has caused exposed soil to wash into the river. The river flows north to south through the town and is still forested both up- and downstream of the town.
A sample of water collected just downstream of the northern forest
Area where new crust is being created at a divergent plate boundary
B
The city of London in the United Kingdom is found approximately at the same latitude as the city of Calgary in Canada. Calgary has an average high temperature in December of −4.6 degrees Celsius, while London has an average high temperature of
Oceanic currents warm the atmosphere in London.
Which of the following best describes why the engineer chose to calculate the permeability of the soil sample in the experimental design in order to evaluate a natural containment system to protect groundwater?
Soils that have low permeability would best help protect groundwater because the soil traps pollutants so that chemical and biological breakdown can occur.
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 the Tropic of Cancer and daylight is less than twelve hours per day.
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.
Based on the diagram, which of the following statements best explains why the climate of the West Coast of Africa is drier than that of the East Coast of the United States, even though they are located at similar northern latitudes?
The cold ocean currents off Africa absorb heat from land and therefore cool the atmosphere.
Which of the following does NOT exert a major influence on Earth's overall climate?
The seasonal development of temperature inversions in geographical basins
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.
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 a primary cause of El Niño climate variations?
Warmer surface waters in the Pacific Ocean
Most of the Earth's deserts are at approximately 30° latitude, north and south, because these latitudes are characterized by
descending dry air currents
Which of the following is a biome found at 30° � and 30° � as seen in the diagram?
deserts
Many synthetic chemicals, such as PCBs, act as estrogen mimics. In an ecosystem, these persistent chemicals would have the greatest effect on which of the following?
secondary consumers
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
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
