Geophysics
Geophysics is a subject of natural science concerned with the physical processes and physical properties of the Earth and its surrounding space environment, and the use of quantitative methods for their analysis.

Hotspot (geology)
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.

Large low-shear-velocity provinces
Large low-shear-velocity provinces, LLSVPs, also called LLVPs or superplumes, are characteristic structures of parts of the lowermost mantle (the region surrounding the outer core) of the Earth.

Outer core
The outer core of the Earth is a fluid layer about thick and composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle.

P-wave
A P-wave is one of the two main types of elastic body waves, called seismic waves in seismology.

Planetary core
The planetary core consists of the innermost layer(s) of a planet; which may be composed of solid and liquid layers.

Post-perovskite
Post-perovskite (pPv) is a high-pressure phase of magnesium silicate (MgSiO3).

S-wave
In seismology, S-waves, secondary waves, or shear waves (sometimes called an elastic S-wave) are a type of elastic wave, and are one of the two main types of elastic body waves, so named because they move through the body of an object, unlike surface waves.

Seismic tomography
Seismic tomography is a technique for imaging the subsurface of the Earth with seismic waves produced by earthquakes or explosions.
New!!: Core–mantle boundary and Seismic tomography · See more »
Seismic wave
Seismic waves are waves of energy that travel through the Earth's layers, and are a result of earthquakes, volcanic eruptions, magma movement, large landslides and large man-made explosions that give out low-frequency acoustic energy.

Silicate
In chemistry, a silicate is any member of a family of anions consisting of silicon and oxygen, usually with the general formula, where 0 ≤ x Silicate anions are often large polymeric molecules with an extense variety of structures, including chains and rings (as in polymeric metasilicate), double chains (as in, and sheets (as in. In geology and astronomy, the term silicate is used to mean silicate minerals, ionic solids with silicate anions; as well as rock types that consist predominantly of such minerals. In that context, the term also includes the non-ionic compound silicon dioxide (silica, quartz), which would correspond to x.

Silicate perovskite
Silicate perovskite (or bridgmanite) is (Mg,Fe)SiO3 and CaSiO3 (calcium silicate) when arranged in a perovskite structure.
