• the thickness of each layer

• the temperature of each layer

Multiple Choice

What distinguishes physical layers of Earth?

• the elements and compounds in each layer

• how rigid each layer is

• the thickness of each layer

• the temperature of each layer

Multiple Choice

Which layer exists as a collection of tectonic plates?

• asthenosphere

• mantle

• lithosphere

• outer core

Multiple Choice

The outer core is a...

• solid

• liquid

• gas

Multiple Choice

The inner core is a...

• solid

• liquid

• gas

Multiple Choice

What is the outermost layer of the Earth called?

• lithosphere

• core

• asthenosphere

• mesosphere

Multiple Choice

Tectonic plates consist of

• continental crust.

• mesosphere.

• both continental and oceanic crust.

• oceanic crust.

Multiple Choice

The place where two plates come together is known as a _______

• transform boundary.

• divergent boundary.

• convergent boundary.

• rift valley.

Multiple Choice

Mountains are created when....

• Two continental plates collide
• Two oceanic plates pull apart
• An Oceanic plate subducts under a Continental Plate
• Two continental plates pull apart

Multiple Choice

A fault is formed by the movement of a __________ plate boundary

• Transform
• Convergent
• Divergent

Multiple Choice

What type of plate boundary is this?

• Plate
• Divergent
• Convergent
• Transform

Multiple Choice

The 2004 Indian Ocean tsunami was caused by a shift in two plates that pushed one section of the sea floor under another section of the sea floor by 5 meters. What type of boundary is this?

• divergent

• convergent

• transform

• metamorphic

Multiple Choice

Trenches, deep underwater canyons on the sea floor are created at this type of boundary 

• Divergent
• Convergent, Subduction Zone
• Transform 

Multiple Choice

This boundary is described as moving toward one another  When the plates are both continental plates the will crumple up and form a mountains. When they are continental and oceanic plates, subduction occurs  and earthquakes and volcanoes form. 

• Convergent Boundary
• Divergent Boundary
• Transform Boundary

Multiple Choice

This boundary is described as two plates moving past eachother ALONG THE EDGES horizontally.  These boundaries will get stuck or lock against eachother causing earthquakes when they slip and release. 

• Convergent Boundary
• Divergent Boundary
• Transform Boundary

Multiple Choice

This boundary is described by two plates moving away from eachother along the edges and separating. The resulting gap allows magma to rise and create new crust, forming new lithosphere. 

• Convergent Boundary 
• Divergent Boundary  
• Transform Boundary

Multiple Choice

How would you describe conditions inside the Earth?

• All areas inside the Earth are just homogeneous.

• The inside of the Earth has a circular structure like an onion

• The inside of the Earth has a structure made of different blocks.

Multiple Choice

How much portion inside the Earth is molten?

• 30%

• 15%

• 75%

• 85%
