What is the crust?
This happens when a layer of rock breaks and moves due to the strain of forces on it.
What is a fold?
The boundary between the crust and the mantle.
How scientists study the structure of the earth beneath the surface.
What are seismic waves?
The innermost layer of the Earth.
What is the core?
This type of fault occurs when rocks long one side of the fault sink vertically.
What is normal?
Rocks that bend downward during the folding process produce these.
What are synclines?
The boundary between the mantle and the core.
The most abundant element in the Earth's crust.
What is oxygen?
The only layer of the Earth thought to be liquid.
What is outer core?
The name of a famous strike-slip fault in California that causes many large earthquakes.
What is the San Andreas?
Rocks that produce anticlines fold this direction.
What is upward?
The area between the upper mantle and the lower mantle.
What is the transition zone?
The number of large plates that make up the earth's crust.
What is 8?
This term describes the rocks of the mantle which means they flow like a thick, syrup in slow motion.
What is plastic rock?

What is reverse?
Creation scientists propose that many of the spectacularly folded rock layers we see now were produced during this event.
A region of the earth's crust and upper mantle.
The average thickness of the crust beneath the continents.
The deeper you go into the Earth, the temperature, pressure, and density do this.
What is increase?
The San Andreas fault marks the boundary between these two plates.
What is the Pacific and the North American?
Folding often occurs in this type of rock.
What is soft sedimentary rock?
The transition zone is about this thick in miles.
The core is thought to be made of these 2 elements.
