Question

Living organisms such as lichens and mosses aid the weathering process.

• A. True
• B. False

Answer 1

The correct option is A True

$\bullet$ Various species of lichens grow onto the rocks. They penetrate and grow within the rock, excreting acids which dissolve minerals, causing the surface to corrode. The surface powders down to form a thin layer of soil.
$\bullet$ Similarly, mosses too, grow over the rocks and release weak acids, breaking the rock into smaller parts.
