100
A naturally occurring, usually inorganic solid that has a definite crystalline structure and chemical composition.
What is a mineral?
100
Ground movements that occur when blocks of rock in Earth move suddenly and release suddenly.
What is an earthquake?
100
The process by which sediment is moved from one place to another.
What is erosion?
100
Describes large-scale movements of Earth's lithosphere, which is made up of the crust and the rigid, upper part of the mantle.
What is plate tectonics?
100
Any place where gas, ash, or melted rock come out of the ground.
What is a volcano?
200
Pure substances that cannot be broken down into simpler substances by ordinary chemical means.
What is an element?
200
A place within Earth along a fault at which the first motion of an earthquake occurs.
What is a focus?
200
The process by which sediment comes to rest.
What is deposition?
200
When the continents were joined in a single large landmass.
What is Pangaea?
200
Melted rock that is less dense than solid rock.
What is magma?
300
The building blocks of matter.
What is an atom?
300
Directly above the focus on Earth's surface.
What is an epicenter?
300
Forms when magma or lava cools and hardens to become solid.
What is Igneous rock?
300
When two plates move away from each other.
What is a divergent boundary?
300
Magma that has reached Earth's surface.
What is lava?
400
A substance made up of molecules of two or more elements.
What is a compound?
400
A break in Earth's crust along which blocks of rock move.
What is a fault?
400
Forms when minerals that form from solutions or sediment from older rocks get pressed and cemented together.
What is Sedimentary rock?
400
Forms when two plates collide.
What is a convergent boundary?
400
The opening of a volcano.
What is a vent?
500
Anything that has volume and mass.
What is matter?
500
The return of rock to its original shape after elastic deformation.
What is elastic rebound?
500
Forms when pressure, temperature, or chemical processes change existing rock.
What is Metamorphic rock?
500
A boundary at which two plates move past each other horizontally.
What is a transform boundary?
500
A location where a column of extremely hot mantle rock, called a mantle plume, rises through the asthenosphere.
What is a hot spot?
