What Is Chemical Weathering? - ThoughtCo
2019年2月18日 · Chemical weathering alters the composition of the rock material toward surface minerals, such as clays. It attacks minerals that are relatively unstable in surface conditions, such as the primary minerals of igneous rocks like basalt, granite or peridotite.
4 Types and Examples of Chemical Weathering - ThoughtCo
2024年8月1日 · Chemical weathering is caused by rocks undergoing chemical reactions to form new minerals. Water, acids, and oxygen are just a few of the chemicals that lead to geological change (weathering). Over time, chemical weathering can produce dramatic results.
Chemical Weathering – Definition, Processes and Types
“Chemical weathering changes the composition of rocks, often transforming them when water interacts with minerals to create various chemical reactions. Chemical weathering is a gradual and ongoing process as the mineralogy of the rock adjusts to the near surface environment.
5.2: Chemical Weathering - Geosciences LibreTexts
2024年4月24日 · Chemical weathering results from chemical changes to minerals that become unstable when they are exposed to surface conditions. The kinds of changes that take place are highly specific to the mineral and the environmental conditions.
Chemical Weathering - Geosciences LibreTexts
Chemical weathering is the main process that drives the carbonate-silicate geochemical cycle. Figure 2 shows how this cycle controls the long term transformation of silicate rocks into carbonate rocks over geologic time.
Weathering - Education | National Geographic Society
2024年4月24日 · Chemical Weathering. Chemical weathering changes the molecular structure of rocks and soil. For instance, carbon dioxide from the air or soil sometimes combines with water in a process called carbonation. This produces a weak …
Chemical Weathering - an overview | ScienceDirect Topics
Chemical weathering refers to the process where minerals undergo a change in composition, transforming from one type to another through reactions such as oxidation, hydrolysis, and carbonation.
