Boundaries
Where two plates collide forming mountains and volcanoes.
What is a convergent boundary?
The outer, solid layer of Earth. (Chemical layer)
What is the crust?
A big landmass of all the continents joined together. A formation from about 245 million years ago.
What is Pangaea?
Any place where gas, ash, or melted rock come out of the ground.
What is a volcano?
Ground movements that occur when blocks of rock in Earth move suddenly and release energy.
What is an earthquake?
Where two plates separate, creating valleys.
What is a divergent boundary?
It goes from below the mantle to the center of the Earth. (Chemical layer)
What is the core?
The process by which rock becomes deformed and changes shape due to stress.
What is deformation?
A. Magma on Earth's surface.
B. Melted rock that is less dense than solid rock.
A. What is lava?
B. What is magma?
A place within Earth along a fault at which the first motion of an earthquake occurs.
What is a focus?
When two plates scrape against each other.
What is a transform boundary?
It is hot, sold rock between the core and crust. (Chemical layer)
What is the mantle?
Stress that stretches and pulls rock apart.
What is tension?
The opening of a volcano.
What is a vent?
The area directly above the focus.
What is an epicenter?
Pieces of lithosphere that move on the asthenosphere.
What are tectonic plates?
The outer rigid layer of Earth. (Physical layer)
What is the Lithosphere?
Stress that squeezes and pushes rock together.
What is compression?
The location where a column of extremely hot mantle rock rises through the asthenosphere.
What is a hot spot?
A break in Earth's crust along which blocks of rock move.
What is a fault?
A. The return of rock to it's original shape after elastic deformation.
B. The movement of matter that result from difference in density and caused by different temperatures.
A. What is elastic rebound?
B. What is convection?
A. The weak and soft mantle. (Physical layer)
B. The strong and lower mantle. (Physical layer)
A. What is the asthenosphere?
B. What is the mesosphere?
Stress that pushes rock parallel but opposite directions.
What is shear stress?
The process to explain the age and magnetic patterns of sea-floor rock.
What is sea-floor spreading?
The process when rocks change shape under stress.
What is folding?
