EVERYDAY SCIENCE

Detailed explanation-1: -Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.

Detailed explanation-2: -Trees put down roots through joints or cracks in the rock in order to find moisture. As the tree grows, the roots gradually prize the rock apart. Many animals, such as these Piddock shells, bore into rocks for protection either by scraping away the grains or secreting acid to dissolve the rock.

Detailed explanation-3: -Biological weathering only refers to weathering caused by plants, animals, fungi, and microorganisms such as bacteria. It is contributed to or removal of ions and minerals from the weathering environment and physical variations due to movement or development of organisms.

Detailed explanation-4: -In this type of weathering, living organisms contribute through their organic compounds that contain molecules that acidify and corrode rock minerals. Because of such a mechanism, biological weathering is also referred to as organic weathering.

Detailed explanation-5: -Burrowing animals. Soil formation is enhanced by many animals, from tiny one-cell organisms to the mammals that make a temporary or permanent home in soil. Organic material. Organic material is added to the soil from the decomposition of animals and plants. Lichens.
