100
The crust, mantle, core of the Earth
What are Earth's compositional layers?
100

What is Pangaea?
100
The crack that forms when large blocks of rock break and move past each other

200
Building blocks of matter
What is an atom?
200
The process in which sediment is moved from one place to another
What is erosion?
200
Movement of matter that results from differences in densities
What is convection
200
The lithosphere is divided into pieces
What is a tectonic plate?
200
Process by which rock changes shape due to stress
What is deformation?
300
By metamorphism, from solution, as magma and lava cool
How are minerals formed?
300
The process in which sediment comes to rest
What is deposition?
300
Most dense compositional layer of the Earth
What is the core?
300
Process when molten rock from inside the Earth rises through cracks in ridges, cools, and forms new oceanic crust.
What is sea-floor spreading?
300
Formed when melted rock erupts from Earth's interior
What is a volcanic mountain?
400
The way a surface reflects light
What is luster
400
Pressure, temperature, or chemical processes change existing rock
What is a metamorphic rock?
400
Lithosphere, Asthenosphere, mesosphere, outer core, and inner core
What are Earth's physical layers?
400
Boundary that forms when two plates collide
What is convergent boundaries?
400
Place within the Earth along a fault at which the first motion of an earthquake occurs
What is the focus?
500
A solid, geometric form that results from a repeating pattern of atoms or molecules
What is a crystal
500
The sinking of regions of the crust to lower elevations
What is subsidence?
500
The physical layer that is the outermost rigid layer of Earth
What is the lithosphere
500
A boundary at which two plates move past each other horizontally
