In geology, a fault is a planar fracture or discontinuity in a volume of rock, across which there has been significant displacement as a result of rock mass movement
Weathering is the breaking down of rocks, soil and minerals as well as wood and artificial materials through contact with the Earth's atmosphere, waters and biological organisms
An atmosphere is a layer of gases surrounding a planet or other material body, that is held in place by the gravity of that body
The biosphere is the global sum of all ecosystems
The hydrosphere is the combined mass of water found on, under, and above the surface of a planet
continental crust
The continental crust is the layer of igneous, sedimentary, and metamorphic rocks that forms the continents and the areas of shallow seabed close to their shores, known as continental shelves
The mantle is a layer inside a terrestrial planet and some other rocky planetary bodies
Surface waves
In physics, a surface wave is a mechanical wave that propagates along the interface between differing media, usually as a gravity wave between two fluids with different densities
hot spots
In geology, the places known as hotspots or hot spots are volcanic regions thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle
A lithosphere is the rigid, outermost shell of a terrestrial-type planet or natural satellite that is defined by its rigid mechanical properties
The asthenosphere is the highly viscous, mechanically weak and ductilely deforming region of the upper mantle of the Earth
inner core
The Earth's inner core is the Earth's innermost part and according to seismological studies, it has been believed to be primarily a solid ball with a radius of about 1,220 kilometres
outer core
The outer core of the Earth is a fluid layer about 2,300 km thick and composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle
In earth science, erosion is the action of surface processes that remove soil, rock, or dissolved material from one location on the Earth's crust, then transport it away to another location
Convection is the movement of groups of molecules within fluids such as liquids or gases, and within rheids
