Geodynamics is a subfield of geophysics dealing with dynamics of the Earth.It applies physics, chemistry and mathematics to the understanding of how mantle convection leads to plate tectonics and geologic phenomena such as seafloor spreading, mountain building, volcanoes, earthquakes, faulting.
The variety of light elements present in Earth's outer core is constrained in part by Earth's accretion. [16] Namely, the light elements contained must have been abundant during Earth's formation, must be able to partition into liquid iron at low pressures, and must not volatilize and escape during Earth's accretionary process. [14] [16]
In geography, exogenous processes all take place outside the Earth and all the other planets. Weathering , erosion , transportation and sedimentation are the main exogenous processes. Asides from climate, exogenous geographic factors are able to contribute to the overall process of distribution, including densities of populations and ...
Earth System science has articulated four overarching, definitive and critically important features of the Earth System, which include: Variability: Many of the Earth System's natural 'modes' and variabilities across space and time are beyond human experience, because of the stability of the recent Holocene.
Geophysics (/ ˌ dʒ iː oʊ ˈ f ɪ z ɪ k s /) 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.
Extensional tectonics is associated with the stretching and thinning of the crust or the lithosphere.This type of tectonics is found at divergent plate boundaries, in continental rifts, during and after a period of continental collision caused by the lateral spreading of the thickened crust formed, at releasing bends in strike-slip faults, in back-arc basins, and on the continental end of ...
Although the terms erosion and denudation are used interchangeably, erosion is the transport of soil and rocks from one location to another, [1] and denudation is the sum of processes, including erosion, that result in the lowering of Earth's surface. [2] Endogenous processes such as volcanoes, earthquakes, and tectonic uplift can expose ...
Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. [2]
