APES Unit 4 Progress Check

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

• The map illustrates a convergent boundary, where tectonic plates collide, and the North American Plate is sliding under the Pacific Plate.

• The map illustrates a divergent boundary, where two tectonic plates are moving away from each other, creating a rift valley.

• 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.

• The map illustrates a subduction zone at the boundary, leading to the formation of long chains of volcanoes.

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.

• A transform plate boundary exists at the Mid-Atlantic Ridge where two plates slide alongside one another, leading to underwater earthquakes.

• =A convergent plate boundary exists at the Mid-Atlantic Ridge where one plate of oceanic crust is subducted beneath a plate made of continental crust, leading to volcanism.

• A convergent plate boundary exists at the Mid-Atlantic Ridge where two plates of continental crust meet, leading to the formation of mountain ranges.

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 illustrates a convergent boundary with earthquakes and possibly volcanoes in the Hawaiian Islands.

• The enclosed area illustrates a transform boundary where two plates slide past one another, resulting in earthquakes of high magnitude in the Hawaiian Islands.

• The enclosed area illustrates a rift valley leading to seafloor expansion near the Hawaiian Islands.

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

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

• A pH meter and conductivity meter

• A soil core kit and a seismograph

• A density gradient tube and a soil triangle

• A quadrat and a transect line

Students want to determine how vegetation affects soil erosion. They collect four soil samples of equal starting mass with different types of vegetative cover, as seen in the table below. Each sample is placed in a three-sided plastic dish that can drain into a beaker and is exposed to the same amount of consistent, steady rainfall for ten minutes. The water and soil runoff are collected in the beaker and separated. The average values for each sample are provided below.

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

• Soil with no grass

• Soil with newly sprouted grass

• Soil with mature grass

• Soil with dead grass

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

• The type of soil

• Initial mass of the soil sample

• Percent change in mass of the soil sample

• Amount of rainfall the soil receives

A group of students wanted to determine if soil texture can vary by location. Several students brought in a sample of soil from their backyards. Each student added their soil sample of equal mass to a jar with exactly the same amount of water, shook the contents so that all soil particles were suspended in the water, and left the jars covered overnight. The next morning, the soil particles had settled out into layers and students could determine the percentage of each type of particle. The results of their soil test are shown below.

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

• Percentage of each particle size in each soil sample

• Soil samples taken from different locations

• Time required for each soil sample to settle

• Addition of water to each soil sample

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 added water to the soil sample and determined the amount of water required to saturate the soil.

• The student oven-dried the soil sample following separation and calculated the percent change in mass of the remaining sand and silt after the sample cooled.

• The student calculated the amount of soil mass lost overnight in each soil sample that resulted from the evaporation of the clay and silt.

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