EVERYDAY SCIENCE

Detailed explanation-1: -Rabbits, by burrowing in to the ground, destroy soft rocks. Moles, ants and bodies of the dead animals, provides substances which react with minerals and aid in decaying process.

Detailed explanation-2: -Biological weathering is caused by the movements of plants and animals. For example, a rabbit can burrow into a crack in a rock making it bigger and eventually splitting the rock, or a plant may grow in a crack in a rock and, as its roots grow, cause the crack to widen.

Detailed explanation-3: -As the roots grow, they widen the cracks, eventually breaking the rock into pieces. Over time, trees can break apart even large rocks. Even small plants, such as mosses, can enlarge tiny cracks as they grow. Animals that tunnel underground, such as moles and prairie dogs, also work to break apart rock and soil.

Detailed explanation-4: -Weathering is the breakdown of rocks and minerals at or near the Earth’s surface. It is caused by chemical and physical interactions with air, water, and living organisms.

Detailed explanation-5: -Weathering can be caused by wind, water, ice, plants, gravity, and changes in temperature.
