Earth and Environmental Quiz

What is the movement of continents resulting from the motion of tectonic plates?

• Seafloor spreading

• Continental drift

• Subduction

• Chemical weathering

What occurs when two plates move apart, causing the new crust to be formed?

• Transform fault boundary

• Divergent plate boundary

• Convergent plate boundary

• Ice wedging

What is the idea or theory that the earth's crust is made of large chunks of land, or plates, that move over time?

• Mechanical weathering

• Oceanic crust

• Ice core

• Plate tectonics

What are cylinders of ice drilled from ice sheets and glaciers, essentially frozen time capsules?

• Subduction

• Constructive force

• Ice core

• Erosion

What is the process that occurs when two tectonic plates meet at convergent boundaries, and one of the plates moves under the other one due to gravity and differences in density?

• Mechanical weathering

• Chemical weathering

• Seafloor spreading

• Subduction

What is the layer of granitic, sedimentary and metamorphic rocks which form the continents?

• Continental crust

• Oceanic crust

• Erosion

• Transform fault boundary

• Ice core

What is the process of molten material from the mantle being pushed upward to the surface of the earth and spreading apart creating new earth?
