Geological Society - Chemical Weathering

There are different types of chemical weathering, the most important are: Solution - removal of rock in solution by acidic rainwater. In particular, limestone is weathered by rainwater containing dissolved CO2, (this process is sometimes called carbonation). Hydrolysis - the breakdown of rock by acidic water to produce clay and soluble salts.

How does the type of rock affect weathering? | AnswersDrive

When the more weather-resistant rock is left behind, this process is called differential weathering. A rock's exposure to the weathering elements and its surface area can affect its rate of weathering. As a rock goes through chemical and mechanical weathering, it is broken into smaller rocks.

Processes of Chemical Weathering - CliffsNotes

Solution weathering is the process by which certain minerals are dissolved by acidic solutions. For example, calcite in limestone is dissolved easily by carbonic acid. Rain that percolates through cracks and fissures in limestone beds dissolves calcite, making wider cracks that can ultimately develop into cave systems. Oxygen.

How does chemical weathering cause caves to form in limestone?

Limestone caves. Caves form in limestone (calcium carbonate), and occasionally in dolomite (calcium magnesium carbonate), when water containing dissolved carbon dioxide (carbonic acid) seeps into rock crevices and joints. This leads to further enlarging and sculpturing of the caves by chemical and physical weathering.

Chemicals found in limestone readily react with weak acids while granite rocks are more resistant. Exposure. Rocks that are exposed to the surface tend to be weathered faster than bedrock which is covered. However mechanical weathering processes such as pressure release can still occur if the overburden is being removed by denudation processes.

Rates of Weathering

1 As dramatic as the process of weathering sounds, it does not happen overnight. In fact, some instances of mechanical and chemical weathering may take hundreds of years. An example would be the dissolving of limestone through carbonation. Limestone dissolves at an average rate of about one-twentieth of a centimeter every 100 years.

Weathering Processes | Physical Geography

Weathering Processes. Weathering is the process that changes solid rock into sediments. With weathering, rock is disintegrated into smaller pieces. Once these sediments are separated from the rocks, erosion is the process that moves the sediments away from it’s original position. The four forces of erosion are water, wind, glaciers, and gravity.
