Which is an example of physical weathering Brainly?

Explanation: physical weathering is rocks, soil and minerals being slowly broken down or broken apart by the Earth’s environment such as pressure, temperature, water and ice. An example of physical weathering is a large rock located under a waterfall turning smooth from the pounding water.

What are examples of physical and chemical weathering?

Physical, or mechanical, weathering happens when rock is broken through the force of another substance on the rock such as ice, running water, wind, rapid heating/cooling, or plant growth. Chemical weathering occurs when reactions between rock and another substance dissolve the rock, causing parts of it to fall away.

What are examples of weathering?

Weathering is the wearing away of the surface of rock, soil, and minerals into smaller pieces. Example of weathering: Wind and water cause small pieces of rock to break off at the side of a mountain. Weathering can occur due to chemical and mechanical processes.
