Physical weathering, also called mechanical weathering or disaggregation, is the class of processes that causes the disintegration of rocks without chemical change. Physical weathering involves the breakdown of rocks into smaller fragments through processes such as expansion and contraction, mainly due to temperature changes.
Tectonic–climatic interaction is the interrelationship between tectonic processes and the climate system. The tectonic processes in question include orogenesis, volcanism, and erosion, while relevant climatic processes include atmospheric circulation, orographic lift, monsoon circulation and the rain shadow effect.
A climate model is a representation of the physical, chemical and biological processes that affect the climate system. [172] Models include natural processes like changes in the Earth's orbit, historical changes in the Sun's activity, and volcanic forcing. [ 173 ]
On million-year time scales, the carbonate-silicate cycle is a key factor in controlling Earth's climate because it regulates carbon dioxide levels and therefore global temperature. [3] The rate of weathering is sensitive to factors that change how much land is exposed. These factors include sea level, topography, lithology, and vegetation ...
The five components of the climate system all interact. They are the atmosphere, the hydrosphere, the cryosphere, the lithosphere and the biosphere. [1]: 1451 Earth's climate system is a complex system with five interacting components: the atmosphere (air), the hydrosphere (water), the cryosphere (ice and permafrost), the lithosphere (earth's upper rocky layer) and the biosphere (living things).
Abrasion is a process of weathering that occurs when material being transported wears away at a surface over time, commonly occurring with ice and glaciers. The primary process of abrasion is physical weathering. Its the process of friction caused by scuffing, scratching, wearing down, marring, and rubbing away of materials.
Climate, most directly through chemical weathering from rain, but also because climate dictates what kind of weathering occurs; [7] Lithology or the type of rock; Surface topography and changes to surface topography, such as mass wasting and erosion; [ 8 ] and
The climate system will vary in response to changes in forcings. [15] The climate system will show internal variability both in the presence and absence of forcings imposed on it. This internal variability is a result of complex interactions between components of the climate system, such as the coupling between the atmosphere and ocean. [16]
