The root “bio” means “life”. ]]> 2019-01-17 03:29:07 UTC https://padlet.com/abihamajid0/chfrodez2rd1/wish/321532310 Types of biological weathering by chemical and physical means: abihamajid0 https://padlet.com/abihamajid0/chfrodez2rd1/wish/321532709 * Plants

They become more easy to break and they eventually fall part.]]> 2019-01-17 03:41:05 UTC https://padlet.com/abihamajid0/chfrodez2rd1/wish/321533743 Biological weathering by animals: abihamajid0 https://padlet.com/abihamajid0/chfrodez2rd1/wish/321534171 When animals like birds forage for seeds and earthworms, they create holes and erode the upper surface of the soil and this contributes to weathering.

Walking or running makes the soil particles crushed into smaller pieces. Other human activities such as planting and road construction can also contribute to biological weathering.

Such minerals are then consumed by the alga, further causing the wearing and development of cracks and gaps on the rock. As a result, cracked rocks become more prone to disintegration.
