When tectonic plates move away from each other
What is a divergent boundary?
100
The thin, outermost layer of the Earth.
What is the crust?
100
A piece of the lithosphere that moves around on top of the asthenosphere.
What is tectonic plates?
100
The bending of rock layers due to stress in the Earth's atmosphere.
What is folding?
100
A mountain of hill in which lava from the Earth's core comes out of the Earth.
What is volcano?
200
The boundary between two converging tectonic plates.
What is a convergent boundary?
200
The layer of the Earth between the crust and the core.
What is the mantle?
200
The theory that the continents can drift apart and have done so in the past.
What is continental drift?
200
A break in the Earth's crust along which blocks of the crust slide relative to one another.
What is faulting?
200
A broad, domed volcano with gently sloping sides.
What is shield volcano?
300
The boundary between two tectonic plates that are sliding past each other horizontally.
What is a transform boundary?
300
The central, spherical part of the Earth below the mantle.
What is the core?
300
The process by which new oceanic lithosphere is created at mid-ocean ridges as old materials are pulled away from the ridge.
What is sea-floor spreading?
300
A fault in which the hanging wall moves down the relative foot wall.
What is normal fault?
300
Steep hills conical hill of tephra that accumulates around a volcanic vent.
What is cinder cone volcano?
400
The region where a tectonic plate sinks into the asthenosphere at a convergent boundary.
What is subduction zone?
400
The outermost, rigid layer of the Earth that consists of the crust and the rigid part of the mantle.
What is lithosphere?
400
The theory that Earth's lithosphere is divided into pieces that move around on top of the asthenosphere.
What is plate tectonics?
400
A fault in which the hanging wall moves up the relative foot wall.
What is reverse fault?
400
A conical volcano built up with many layers of hardened lava.
What is composite volcano?
500
The amount of force per unit that is put on an object.
What is stress?
500
The soft layer of the mantle on which pieces of the lithosphere move.
What is asthenosphere?
500
The strong, lower part of the mantle between the asthenosphere and the outer core.
What is mesosphere?
500
A fault in which two fault blocks move past each other horizontally.
What is stripe-slip fault?
500
A small area or region with relatively hot temperature in comparison to its surroundings.
What is hot spot?
