Savvas Plate Tectonics Review

Why is this most likely the case?

• Earthquakes can only happen near volcanic eruptions, and most volcanoes occur on or near plate boundaries.

• Tectonic plates move along, against, or away from each other at their boundaries. These movements produce earthquakes.

• Many plate boundaries are bordered or covered by the ocean. Water from the ocean seeps into earthquake fault lines, softening the rock materials so that they can move and cause earthquakes.

• Seismic waves transmit through different media at different speeds. Subduction zones at plate boundaries are ideal for transmission of these waves.

A subduction zone is an area where one tectonic plate sinks underneath another one. Volcanoes often form as a result. Which of the following plate collisions would most likely result in a subduction zone?

• a piece of continental crust and a piece of oceanic crust meeting at a divergent boundary

• a piece of continental crust and a piece of oceanic crust meeting at a convergent boundary

• two pieces of oceanic crust meeting at a divergent boundary

• two pieces of continental crust meeting at a divergent boundary

Before the present theory of plate tectonics, scientists used the hypothesis of continental drift to propose that Earth's continents are in motion. Which of the following were initially used to support the hypothesis of continental drift?

• I and IV only

• I, II, III, and IV

• II and III only

• II, III, and IV only

The image shows a convergent plate boundary.

Based on the image, which of the following would most likely form at point X as a result of the converging plates?

• marshes

• deltas

• mid-ocean ridges

• volcanoes

Which of the following events would most likely produce an earthquake?

• Along mountain slopes, heavy rocks fall, creating shocks that travel through the land.

• At transform plate boundaries, tectonic plates rub against each other with great force.

• During flooding, water exerts pressure on the land, causing wide cracks in the ground.

• During thunderstorms, lightning generates shocks that pass through the Earth’s crust.

Given is a map of the west coast of the United States. The red line depicts the San Andreas Fault, a transform boundary that runs parallel to the coast. The San Andreas Fault separates the North American plate on the east from the Pacific plate on the west.

Based on this information, which of the following most likely occurs near the San Andreas Fault?

• deposition of sediment

• subduction of oceanic crust

• frequent earthquakes

• frequent droughts

What is Pangaea?

• a complex theory that explains the motions of continents and many of Earth's features

• a species whose fossilized remains in Africa led to the hypothesis of continental drift

• a single, large landmass in which all of Earth's continents were once joined

• a mid-oceanic ridge than runs from north to south along the Atlantic Ocean's floor
