Quizplus · Accepted Answer

All of the listed biological processes can weather the landscape. The burrowing of animals can create tunnels that expose rock to weathering agents, while also contributing organic matter to the soil. Lichens exchanging ions with rocks can chemically break down minerals, contributing to the breakdown of rock. Root wedging occurs when roots of plants grow into cracks in rocks and exert pressure as they expand, which can cause the rock to break apart. All of these biological processes can contribute to the weathering of the landscape.
