Question

Differentiate between the following : Physical Weathering Chemical Weathering

Answer 1

1. While physical weathering breaks down a rock's physical structure, chemical weathering alters a rock's chemical composition. Physical weathering works with mechanical forces, such as friction and impact, while chemical weathering takes place at the molecular level with the exchange of ions and cations.

Answer 2

Answer:

Physical weathering is caused by the effects of changing temperature on rocks, causing the rock to break apart. The process is sometimes assisted by water,While physical weathering breaks down rocks without altering their composition, chemical weathering alters the chemicals that compose the rocks. Depending on the chemicals involved, the rock might disintegrate entirely, or might simply become softer and more vulnerable to other forms of weathering. Physical and chemical weathering often work hand in hand: chemical weathering weakens the rock and physical weathering breaks it down.
