The Earth and oceanic crusts are made up of several tectonic plates, masses of solid matter that sit atop the liquid mantle of Earth. The plates are constantly moving, evidence of which can be seen in the topography of Earth’s surface, the topography of the oceanic crustal surface, and by the frequent occurrence of Earthquakes near fault lines (plate boundaries).
Plates are said to by convergent if they are moving towards one another. The eventual meeting of convergent plates causes uprisings, often in the form of mountains. Divergent Plates are moving away from one another and have caused the gradual shift in continental placement, as well as numerous basins and trenches.
Figure 1 shows a diagram of an oceanic and continental plate. The arrows represent the direction of plate movement.
Figure 2 shows a close-up section of the continental crust from Figure 1, sampled near the fault line.

According to the passage, which type of plates are shown in Figure 1?CorrectIncorrect
Faulting is a term given to rock layers that have shifted due to tectonic plate movement. Given this information and the information provided, would one expect to find faulting within the continental crust in Figure 1, and for what reason?CorrectIncorrect
Based on Figure 2, which layer of rock is most likely the oldest?CorrectIncorrect
Based on Figure 1 and the information provided in passage, what is the most likely explanation for the arrangement of rock layers A through D?CorrectIncorrect
The Rocky Mountains extend along the Western parts of the United States into Canada. Geologists have concluded that the Rocky Mountains are a result of a major uprising 120 million years ago. Based on this and the information in the passage, which of the following statements is most likely true?CorrectIncorrect
