rock weathering

Rock weathering is the natural process that breaks down rocks into smaller particles or alters their composition over time. It occurs through physical means, like temperature changes causing rocks to crack, or through chemical processes, such as water reacting with minerals to form new substances. Biological activity, like plant roots and microorganisms, can also contribute by breaking apart rocks or producing chemicals that facilitate breakdown. Weathering is a key part of the Earth's cycle, gradually transforming solid rock into soil and sediment, influencing landscapes and supporting various ecosystems.
