Earth science
Many scientists are now
starting to use an approach
known as Earth system
science which treats the
entire Earth as a system in
its own right, which evolves
as a result of positive and
negative feedback between

Continental crust
The continental crust is the
layer of granitic,
sedimentary and metamorphic
rocks which form the
continents and the areas of
shallow seabed close to
their shores, known as
continental shelves. It is

Mid-ocean ridge
A mid-ocean ridge or
mid-oceanic ridge is an
underwater mountain range,
formed by plate tectonics.
This uplifting of the ocean
floor occurs when convection
currents rise in the mantle
beneath the oceanic crust

Elastic-rebound theory
In geology, the elastic rebound theory was the first theory to satisfactorily explain earthquakes. Previously it was thought that ruptures of the surface were the result of strong ground shaking ... > more -
Groundwater
Groundwater is water located beneath the ground surface in soil pore spaces and in the fractures of geologic formations. A formation of rock/soil is called an aquifer when it can yield a useable ... > more -
Geologic fault
Geologic faults or simply faults are planar rock fractures which show evidence of relative movement. Large faults within the Earth's crust are the result of shear motion and active fault zones are ... > more -
Supervolcano
A supervolcano refers to a volcano that produces the largest and most voluminous kinds of eruption on Earth. The actual explosivity of these eruptions varies, but the sheer volume of extruded magma ... > more -
Seismic wave
A seismic wave is a wave that travels through the Earth, most often as the result of a tectonic earthquake, sometimes from an explosion. There are two types of seismic wave, namely, 'body wave' and ... > more -
Mantle plume
A mantle plume is an upwelling of abnormally hot rock within the Earth's mantle. As the heads of mantle plumes can partly melt when they reach shallow depths, they are thought to be the cause of ... > more -
Circle of latitude
On the Earth, a circle of latitude or parallel is an imaginary east-west circle that connects all locations with a given latitude. The position on the circle of latitude is given by the longitude. ... > more
