It forms when magma or molten rock, cools and harden. Magma is called lava when it exposed at Earth's surface.
Deposits are compressed, comented together and harden, sedimentary rock forms.
Forces and processes, including tremendous [ressure, extreme heat and chemical processes,
also can change the form of existing rock.
Form when magma makes its way to Earth's surface. The molten rock erupts or
flows above the surface as lava, and then cools forming rock.
Rocks formed from the cooling and solidification of magma beneath Earth Surface.
A nonrenewable energy source that formed from the remains organisms that lived long ago;
Example:
Oil, Coal and Natural Gas
A break in a body of rock along which one block slides relative to another; a form a battle strain
A form of ductile strain in which rock layers bend, usually as a result of compression
A movement or trembling of the ground that is caused by a sudden release of energy when rocks along a fault move
A giant ocean wave that forms from a volcanis eruption, submarine earthquake, or landslide
An instrument that record vibrations in the ground
A primary wave, or compression wave; seismis wave that causes particles of rock to move in back-and-forth.
They're the fastest seismic waves and can travel through solid, liquids and gases
A secondly wave, or shear wave; a seismic wave that causes particles rock to move in side-to-side.
They're the second-fastest seismic waves and can travel only trough solids.
Where one tectonic plate moves under another
Form underwater mountain ranges that run along the floors of all oceans
A volcanically active area of Earth's surface, commonly far from a tectonic plat boundary
Describes magma or igneous rock that is rich in magnesium and iron that is generally dark in color
Describes magma or igneous rock that is rich in fedspar and silica and that is generally light in color
