Plate tectonics
The continents were joined on a single large mass.
What is Pangea?
The process by which rocks change shape when under stress.
What is Deformation?
Any place where gas, ash, or melted rock come out of the ground.
What are volcanoes?
The ground movement that occurs when blocks of rock in Earth move suddenly and release energy.
What are earthquakes?
The pieces of the lithosphere.
What are tectonic plates?
The youngest layers of rock are found at the core of a fold.
What are synclines?
Magama that has reached Earth's surface.
What is lava?
A place within Earth along a fault at which the first motion of an earthquake occurs.
What is focus?
Where two plates collide.
What are convergent boundaries?
The oldest layers of rock that are found at the core of the fold.
What are anticline?
The resistance of a liquid material, such as lava to flows.
What is viscosity?
A break in Earth's crust along which blocks of rock move.
What is fault?
Two plates move away from each other.
What are divergent boundary?
A process that can cause the land to rise can also contribute to mountain building.
What is uplift?
An opening or depression at the top of a volcano caused by eruptions.
What is a volcano crater?
The return of rock to its original shape after deformation.
What is elastic rebound?
Drags plates along as mantle material move beneath tectonic plates.
What is mantle convections?
Rock layers are squeezed together and pushed upward.
What are folded mountains?
A thick and most flattened layer of cooled lava.
What are lava plateaus?
A series of extremely long waves that can travel across the ocean at speed of up to 800km/hr.
What is a tsunami?
