Is a term used in science that refers to the geological process of rocks breaking apart without changing their chemical composition.
Physical Weathering
the erosion or disintegration of rocks, building materials, caused by chemical reactions (chiefly with water and substances dissolved in it) rather than by mechanical processes.
Chemical Weathering
wear away or change the appearance or texture of (something) by long exposure to the air.
Weathering
According to an ongoing temperature analysis conducted by scientists at NASA's Goddard Institute for Space Studies
temperture changes
The changes in its level were caused by changes in the atmospheric pressure. ... Air pressure is regularly recorded as inches of mercury
presasure changes
the perceptible natural movement of the air, especially in the form of a current of air blowing from a particular direction.
wind
Mechanical weathering physically breaks up rock. One example is called frost action or frost shattering.
plant action
Is the mechanical scraping of a rock surface by friction between rocks and moving particles during their transport by wind, glacier, waves, gravity, running water or erosion.
abrasion
Worn away or broken down into smaller and smaller pieces. There are mechanical, chemical and organic weathering processes.
Water
Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity.
gravity
When animals burrow in the ground they brake up part of the soil and brake the rock up.
animal action
Is also a contributor to chemical weathering
acid rain
