Plate Tectonics Review

Multiple Choice

What are the two main components that make up the lithosphere?

• Upper mantle and crust

• Outer core and inner core

• Asthenosphere and mantle

• Crust and core

Multiple Choice

The diagram illustrates the movements of tectonic plates on Earth. Which statement best describes this diagram?

• It shows the convection currents in the mantle.

• It shows the convection currents in the outer core.

• It shows the radiation of heat through the mantle.

• It shows the conduction of heat in the mantle.

Open Ended

How does this picture of mountain ranges made of the same rock material on different continents support the theory of continental drift?

Multiple Choice

What role do convection currents play in the movement of tectonic plates?

• They cool the plates down

• They move the plates as the core heats the asthenosphere

• They create earthquakes

• They form mountains

Multiple Choice

What type of boundary is found down the middle of the Atlantic Ocean?

• Divergent

• Convergent

• Transform

• Atlantis

Multiple Choice

If you took rock samples from the Mid-Atlantic Ridge, the youngest rock would be

• located where the plates collide

• located at the place where rocks are furthest from the rift valley

• Located at the center of the ridge, where oceanic crust is formed

• none of the above; all the rocks would be the same age

Multiple Choice

What causes rift valleys to form?

• Rift valleys form where two continental plates diverge, or move away from each other

• Rift valleys form where two continental plates converge, or move toward each other

• Rift valleys form where one oceanic plate subducts beneath another continental plate

• Rift valleys form at transform boundaries

Multiple Choice

Which of these events can ONLY happen on a DIVERGENT BOUNDARY?

• Rift Valley
• Mountain
• A peninsula
• An Insanely complex, long answer that you will click out of instinct. 

Multiple Choice

What is a hot spot in geology?

• A place to get free wifi

• A column of mantle that is hotter than the surrounding material

• A tectonic plate boundary

• A type of earthquake

Multiple Select

What are the two examples of hotspots shown in the images?

• Hawaii

• Yellowstone Park

• Mount St. Helens

• Kilauea

Multiple Choice

What happens where an oceanic plate converges with a continental plate?

• The denser oceanic plate slides on top of the less dense continental plate.

• The denser oceanic plate slides under the less dense continental plate.

• The less dense oceanic plate slides past the denser continental plate.

• The less dense oceanic plate slides under the denser continental plate.

Multiple Choice

When oceanic and continental crust converge, the oceanic plate will dive beneath the continental plate. What best explains the results of this action?

• The oceanic crust is moved upward by the radiation of heat

• The oceanic crust will melt as it moves deeper in the earth.

• The continental crust will form a mountain range.

• The two crusts will form an ocean basin

Multiple Choice

What are the characteristics of island arcs and volcanic mountains?

• They are formed by a plate melting at a subduction zone

• They are always found in the ocean

• They are only found in tropical warm regions of the planet

• They form due to pressure from the atmosphere

Multiple Choice

What happens when an ocean plate collides with another ocean plate?

• The older plate slides under the younger plate

• The younger plate slides under the older plate

• Both plates move apart

• Both plates remain stationary

Multiple Choice

What are the main features of the Himalayan Mountains?

• They are the highest mountains in the world

• They are located in the USA

• They are formed by volcanic activity

• They are primarily made of sandstone

Multiple Choice

What are the features of transform boundaries as illustrated in the images?

• Earthquakes

• Volcanoes

• Mountain Ranges

• Tsunamis
