Unit 4 Progress check

Based on the diagram, which of the following days in Earth's yearly orbit would have the longest period of daylight in the Northern Hemisphere?

June solstice

Which of the following abiotic factors, when graphed on the x-axis, leads to the curved line in the graph due to variation in the different layers of the atmosphere?

Temperature gradients

Which of the following combinations correctly identifies and explains the effects of the differences in the distribution of solar radiation on Earth as seen in the diagram above?

Global wind patterns are created because uneven solar radiation results in warm air at low latitudes and cool air at high latitudes, resulting in density differences between the air masses.

During a La Niña event, what environmental changes would the tropical Pacific Ocean and its surrounding landmasses most likely experience?

Increased upwelling off the coast of South America resulting in increased productivity of fisheries

Which of the following describes the dependent variable in this investigation?

Percentage of each particle size in each soil sample

Which statement is best illustrated in the diagram above regarding how the Sun's energy affects the Earth's surface from June through September in the Northern Hemisphere?

The season changes from summer to autumn, daylight hours decrease, and infrared radiation is the strongest during the June solstice.

Which of the following would be most helpful to determine the soil texture of a sample?

A density gradient tube and a soil triangle

The Atlantic Ocean is expanding as a result of plate tectonics. Which of the following explanations best identifies the type of plate boundary and processes occurring at the Mid-Atlantic Ridge, as shown in the diagram below?

A divergent plate boundary exists at the Mid-Atlantic Ridge where plates move away from one another, leading to seafloor spreading.

The Chesapeake Bay is a watershed that is located in six states and the District of Columbia. Which of the following can cause an increase in water pollution in the watershed?

An increase in stormwater runoff in urban areas

Based on the diagram, which of the following describes why the summer solstice in Australia occurs in December and not in June?

At this time of year, the tilt of Earth causes Australia to receive highly concentrated solar radiation.

Based on the map above, which of the following best explains why the Atacama Desert has a consistently arid climate?

It is in the rain shadow of the Andes Mountains.

Peru's commercial anchovy industry would most likely be harmed during an El Niño Southern Oscillation (ENSO) event. Which of the following is the most likely explanation for the decline in anchovy during an El Niño Southern Oscillation (ENSO) event?

Less nutrient-rich water reaches surface waters, disrupting the food web.

Based on the map, which of the following best explains the area of the Andes Mountains that would have the greatest number of rivers?

More rivers would be located on the east side of the Andes Mountains because the trade winds are coming from the east.

Which of the following is a dependent variable in the experiment?

Percent change in mass of the soil sample

The Mississippi watershed is the largest in North America, draining all or part of thirty-two states in the United States and two Canadian provinces. A new apartment complex is being built on a steep slope near the source of the Mississippi River outside of Minneapolis, Minnesota. Which of the following measures should be taken to best reduce erosion at the construction site to protect the Mississippi watershed?

Plant grass and shrubs on the slope.

A developer wants to develop a large tract of land near a watershed, which will require the removal of several large trees. Which of the following statements best describes the impact that the development would have on the watershed?

Removing large trees would cause an increase in temperature and keep the surrounding water and soil warmer.

Which of the following describes the independent variable in this investigation?

Soil samples taken from different locations

Which of the following is the control group for this experiment?

Soil with no grass

The vast majority of ozone (O3) is found in a thin layer due to a lack of circulation in which of the following atmospheric layers?

Stratosphere

Which of the following is the best explanation for the formation of Hadley cells in the tropics, as seen in the diagram, between 30°N and 30°S latitude?

The Sun warms the moist air at the equator and causes it to rise because of its lower density. As the warm air moves away from the equator, it cools, becomes denser, and then sinks.

Based on the map above, which of the following best identifies and explains the region of South America that would have a more moderate climate?

The east coast would have a more moderate climate because of the Brazil Current.

The map above shows the locations of known volcanoes and earthquakes. Which of the following explains what is being illustrated in the enclosed area in the northwest portion of the map?

The enclosed area shows a hot spot in the middle of the Pacific Plate in the Hawaiian Islands.

Which of the following statements best describes the boundary between the two tectonic plates seen in the map?

The map illustrates a transform boundary, where tectonic plates slide past each other as the Pacific Plate moves northwest and the North American Plate moves southeast.

A student claims that soil sample B would be classified as a loam. Which of the following best describes the method used by the student to reach this conclusion?

The student used a soil triangle to determine where the lines intersect for sand, silt, and clay for the soil sample.

Which of the following is the best explanation for the deflection of the trade winds in both hemispheres, as seen in the diagram above?

The wind is deflected west because of Earth's rotation.

Which of the following layers of the atmosphere contains charged gas molecules that glow and produce light when hit by solar energy, leading to glowing gases such as the northern lights, found over 90 kilometers above Earth's surface?

Thermosphere

During an El Niño event, farmers in the southwestern United Stated often benefit from which of the following climatic changes?

Wetter and warmer weather that increases soil moisture
