How can the cause of most earthquakes BEST be described?

• The rock in the interior of a tectonic plate is stronger, so it does not deform.

• Earthquakes take place where the motions of tectonic plates transfer energy to rock.

• Earthquakes can only occur at places where magma can reach the surface and transfer energy to rocks.

• Earthquakes take place when one plate moves over another plate, which happens only at plate boundaries.

The diagram shows a cross-section of layers.

Descriptions of superposition are listed. Which statements describe the different evidence for a change due to superposition?

• A. limestone forms in warm, shallow seas

• The rock layers are folded where two continents collided.

• C surface is flat and covered in a layer

• The rocks were uplifted, eroded, and weathered.

  
  

• B. Plates that make Earth’s surface move

• When the limestone layer was deposited, this region was located in a shallow sea.

This graph models the ages of rock in an ocean floor in millions of years ago (Ma). Which statement describes the evidence for plate tectonics based on the data in the model?Which statement describes the evidence for plate tectonics based on the data in the model?

• The data show that continents are sliding across the ocean floor.

• The data show that continents move by pushing through the ocean floor.

• The data show that continents move as the sizes and shapes of the ocean floor change.

The North American plate is moving away from the Eurasian plate. The diagram describes this process in Iceland.

Which statement describes what plate tectonics is LIKELY to cause based on the theory of plate tectonics?

• • Sea levels will rise, eroding the coastline near the ridge.

• • Seawater will erode the land underneath the ridge, creating caves.

• • Volcanic activity will shape the land along the ridge through plate fissures.

• Plate movement will cause tsunamis to flood and erode the coastline near the ridge.
