100
A pure substance that cannot be broken down into simpler substances.
What is an element?
100
A boundary that forms when 2 plates collide.
What is a convergent boundary?
100
The ground movements that occur when blocks of energy move and release energy in the Earth.
What is an Earthquake?
100
Melted rock that lies beneath the surface of the earth.
What is magma?
100
The portion of Earth that extends from the mantle to its center.
What is the core?
200
A substance that is made up of 2 or more elements.
What is a compound?
200
A theory that the seafloor moves due to the movement of tectonic plates.
What is seafloor spreading?
200
The fault where Earthquakes can occur on convergent boundaries.
What are reverse faults?
200
The opening of a volcano.
What is a vent?
200
Earth can be based on chemical composition. These layers are classified by its chemical composition.
What is a compositional layer?
300
The tendency of a mineral to split along specific planes of weakness to form smooth surfaces.
What is cleavage?
300
Pieces of the lithosphere that move on top of the asthenosphere.
What are tectonic plates?
300
A gigantic wave that is caused by the movements and displacement of water an Earthquake creates.
What is a tsunami?
300
A basin shaped depression that forms after the roof of a magma chamber has collapsed.
What is a caldera?
300
The outermost solid layer of earth.
What is a crust?
400
A way of telling apart minerals by looking at how their surface reflects light.
What is luster?
400
A boundary that forms when 2 tectonic plates move past each other horizontally.
What is a transform boundary?
400
A break in Earth's crust along which blocks of energy move.
What is a fault?
400
A giant crack in the Earth from which lava flows.
What is a fissure?
400
Is a liquid layer of earths core.IIt lies beneath the mantle and surrounds the inner core.
What is the outer core?
500
A compound that forms when the elements of aluminum or iron combine with oxygen.
What is an oxide?
500
The theory that tectonic plates move due to the cooling, densifying and gravitational strain on the plates.
What is a ridge push?
500
The return of a rock to its original shape.
What is elastic rebounding?
500
The resistance of a liquid material, like lava, to flow.
What is viscosity?
