Volcano
Any place where gas, ash, or melted rock comes 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?
The continents in a single large landmass around 245 million years ago.
What is Pangaea?
A crack that forms when large blocks of rock break and move past each other.
What is a fault?
The outermost solid compositional layer of Earth.
What is crust?
Magma that has reached Earth's surface.
What is lava?
When rock becomes deformed and changes shape due to stress.
What is deformation?
A process to explain patterns of the sea floor rocks and the age of them.
What is sea floor spreading?
This occurs when rock layers bend under stress.
What is folding?
It is between the crust and core, hot and slow moving rock.
What is the mantle?
Where extremely hot mantle rock rises through the asthenosphere.
What is a hot spot?
When rock returns to normal shape after rock becomes deformed.
What is elastic rebound?
A large scale movement of the Lithosphere.
What is a plate tectonic?
This type of stress pulls rock apart.
What is tension?
The crust and outermost physical layer of Earth.
What is the lithosphere?
When a roof of a magma chamber collapses and leaves an opening/
What is a caldera?
This type of fault is common at the upper crust, and usually occur about 50km deep.
What is a strike slip fault?
Movement of material due to differences in density.
What is convection?
This type of stress squeezes rock.
What is compression?
The layer with weak and soft mantle, and tectonic plates move on top of it.
What is the asthenosphere?
When lava flows from giant crack or fissures in Earth's surface and has no central opening.
What are fissure eruptions?
A series of long waves that can travel across the ocean at speeds of 800km/h.
What is a tsunami?
When older rock moves away from mid ocean ridges as rock cools and becomes denser.
What is ridge push?
This type of stress pushes rocks in a parallel, but opposite direction.
What is shear stress?
The strong, lower part of the mantle, the rock moves slowly.
What is the mesosphere?
