Volcanoes
Mountains
Earthquakes
Earth's Layers
100
A place where gas, ash, or molten rock come out of the ground.
What is a volcano?
100
A crack that forms when large rocks move past each other.
What is a fault?
100
Ground movement on Earth's surface when tectonic plates move and release energy.
What is an earthquake?
100
The outermost solid layer.
What is the crust?
200
This happens at divergent boundaries, convergent boundaries, and hot spots.
Where do volcanoes form?
200
The process in which rock changes shape due to stress.
What is deformation?
200
A place within a fault where the first motions of an earthquake begin.
What is the focus?
200
The outermost rigid layer.
What is the lithosphere?
300
olten rock.
What is magma?
300
Stress that pushes rocks in parallel.
What is shear stress?
300
This is directly above the Earth's Surface, above the focus.
What is the epicenter?
300
Movement of matter that results in density caused by variations in temperature.
What is convection?
400
A location of extremely hot mantle rock.
What is a hot spot
400
Stress that squeezes or pushes rocks together.
What is compression?
400
The place where two tectonic plates meet.
What is a tectonic plate boundary?
400
A layer of weak or soft mantle.
What is the asthenosphere?
500
The opening of a volcano.
What is a vent?
500
When rocks break under stress.
What is folding?
500
When rocks change back to their original state after deformation.
What is elastic rebound?
500
The strong lower mantle.
What is the mesosphere?
