Plate Tectonics Review

Plate tectonics causes all of the following EXCEPT–

1. 
   

• 1.  mountain building.

• 1. ocean basin formation.

• 1.  meteor showers.

• 1. earthquakes and volcanoes.

• 1. A and L are the youngest. The newest rock forms at the edges and moves toward the center as it ages. 

• 1. F and G are the youngest. The newest rock forms at the center and moves toward the edges as it ages. 

• 1. A and F are the youngest. The newest rock forms on the left and moves toward the right as it ages. 

• 1. G and L are the youngest. The newest rock forms on the right and moves toward the left as it ages. 

Answer explanation

The newest rock always forms in the center of divergent boundaries. The rocks age as the plates continue to move away from each other and are replaced by ever newer rock once again formed in the center.

Match the following

• Transform Boundary

• 
• Divergent Boundary

• 
• Convergent Boundary (Subduction)

• 
• Convergent Boundary (Mountain Building)

• 

3. The earthquakes experienced globally are related to tectonic plates. These events are the result of what process? 

• 1. Two tectonic plates sliding past each other 

• 1. Tectonic plates melting as they slide into the mantle 

• 1. Tectonic plates being weathered over time 

• 1. Two tectonic plates pulling away from each other

Answer explanation

B- Incorrect. California is located along a transform boundary. Transform boundaries do not cause plates to melt into the mantle.

C- Incorrect. Weathering does not impact tectonic plate movement.

D- Incorrect. California is located along a transform boundary. Divergent boundaries occur when two tectonic plates pull away from each other.

Using the image, which of the following makes up the OLDEST Layer

• Limestone #4

• Shale #3

• Sandstone #2

• Shale #1

Answer explanation

The law of superposition states that rock layers are deposited from the bottom up.

How are Hot Spots formed?

• Hot spots are formed in the ocean when magma escapes from the crust, and the plate moves over time, causing a chain of new land formations.

• 1. Hot spots are formed when a volcano erupts in the ocean. 

• 1. Hot spots are formed on land when magma escapes from the crust, and the plate moves over time, causing a chain of new land formations. 

• Hot spots are created by volcanic eruptions on the surface.

At what type of boundaries do volcanoes form?

• Transformative boundaries
• Subduction zones only
• Convergent boundaries

• Fault lines

Which of the following is NOT a result of tectonic plate movement?

• Occurrence of earthquakes

• Development of river deltas

• Creation of ocean trenches

• Formation of mountain ranges

What geological feature is commonly found at divergent boundaries?

• Volcanic arcs

• Mid-ocean ridges

• Fold mountains

• Deep ocean trenches
