Weathering | National Geographic Society
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away.

How Does Weathering Happen? | Sciencing
Weathering is the breakdown of rocks and minerals in situ, meaning it occurs without major movement of the rock materials. Weathering happens through processes or sources in the environment, including events like wind and objects like the roots of plants. Weathering is either mechanical, in which rocks are broken down through an external force, or chemical, which means rocks are broken down through a chemical reaction and change.

Weathering – Wikipedia
Weathering is the deterioration of rocks, soils and minerals as well as wood and artificial materials through contact with water, atmospheric gases, and biological organisms. Weathering occurs in situ (on site, with little or no movement), and so is distinct from erosion, which involves the transport of rocks and minerals by agents such as water, ice, snow, wind, waves and gravity. Weathering …

Weathering – Understanding Global Change
Chemical weathering occurs when the breakdown of rock results from chemical change in the rock, or the when the rock is dissolved away. The rate of these chemical reactions is affected by climatic conditions such as precipitation and temperature, with water and warmer temperatures increasing the rate.

Weathering – British Geological Survey
Physical weathering occurs when physical processes affect the rock, such as changes in temperature or when the rock is exposed to the effects of wind, rain and waves. Water can get into cracks in a rock and, if it freezes, the ice will expand and push the cracks apart. When the ice melts, more water can get into the larger crack; if it freezes …

The principal sources of physical weathering are thermal expansion and contraction of rock, pressure release upon rock by erosion of overlaying materials, the alternate freezing and thawing of water between cracks and fissures within rock, crystal growth within rock, and the growth of plants and living organisms in rock.

What Is Weathering, What Are Its Causes, And How It Relates To Erosion
This form of weathering occurs when water moisture interacts with various metals within an object, which results in an oxidation process (better known as rusting) which weakens the item to the point where corrosion causes it to break apart eventually.

What Is Weathering? How Many Types Of Weathering Processes … – WorldAtlas
Weathering action caused by freezing occurs in places where the environment has adequate moisture, and the temperatures fluctuate between high and low freezing points. Chalk is an example of rock that is most prone to weathering due to frost. Ocean Waves Rocks specifically found around the coastal region experience weathering caused by ocean waves.
