Question

Ramon finds a rock that has a a plant growing out of it at the base of the plant he can see some cracks forming in the Rock what type of physical weathering is this

Answer 1

The physical weathering caused by a plant growing out of a rock and creating cracks is known as biological weathering, a process where living organisms contribute to the breaking down of rocks.

Step-by-step explanation:

The physical weathering process described by the student where a plant grows out of a rock and causes cracks to form is known as biological weathering. This occurs when plants or their roots exert force on the rock causing it to crack and eventually break apart. The roots grow into small crevices and as the plant grows, the roots expand, applying pressure on the rock. Over time, this can cause the rock to fracture and break, contributing to the weathering process.

Examples of physical weathering include frost-wedging, where water enters cracks, freezes, and expands, breaking the rock apart, and exfoliation, where layers of rock are peeled away due to pressure release. However, in the case of the plant and the rock, the primary weathering mechanism is biological activity, which highlights the role of living organisms in the weathering process.

Answer 2

Biological weathering

Step-by-step explanation:

This is an example of biological weathering, where the roots of the plant are causing the rock to crack and break down.
