Detailed explanation-1: -Biological weathering is caused by living organisms. This type of weathering showcases both physical and Chemical Weathering. For example, plant roots penetrate cracks in the rock and slowly break the rock mechanically. The plant roots secrete certain chemicals to extract minerals, causing chemical weathering.

Detailed explanation-2: -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-3: -Biological weathering occurs when plants break up rocks with roots or root exudates. The process is slow, but may strongly influence landscape formation.

Detailed explanation-4: -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-5: -The three main types of weathering are physical, chemical, and biological weathering. Physical weathering is the mechanical breakdown of rocks and minerals. Chemical weathering is the chemical breakdown of rocks. Biological weathering is the breakdown of rock by humans, animals, and plants.
