Question

How can biological weathering result in chemical erosion?

Roots loosen soil and break rocks.
Large herds trample rocks and break up soil.
Plants transpire water vapor.
Bacteria release acids and other agents that break down rock.

Answer 1

Answer:

Biological weathering can result in chemical erosion through the action of bacteria that release acids and other agents that break down rock.

Step-by-step explanation:

As the bacteria colonize rocks and soils, they produce organic acids and other metabolic products that react with the minerals in the rock, causing them to break down and dissolve. Over time, this process can weaken and erode the rock, leading to chemical erosion. Additionally, the action of roots can also contribute to chemical erosion by releasing organic acids into the soil, which can further break down rock and mineral surfaces.

Answer 2

Answer: Biological weathering only refers to weathering caused by organisms -- animals, plants, fungi and microorganisms such as bacteria. While certain forms of biological weathering, such as the breaking of rock by tree roots, are sometimes categorized as either physical or chemical, biological weathering can be either physical or chemical
