Question

difference between chemical weathering and physical weathering​

Answer 1

Explanation:

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:

The answer is here:

##1.) Chemical Weathering:

Chemical weathering is defined as weathering that results in the alteration of the molecular structure of rocks and soil. These reactions can take place over very long periods of time; whereas the biochemical reactions in your body are catalyzed by enzymes that greatly speed them up, in chemical weathering the reactions usually must unfold without outside help.

Many areas can experience multiple types of weathering simultaneously. For example, if soil slides down into standing water as a result of mechanical forces, materials in the water or the water itself may react with these rocks and soil to produce changes to the environment. Some of these changes can greatly impact the local ecosystem, i.e., the living things in a particular place and the nature of their interactions.

##2.) Physical Weathering:

Physical weathering describes a change that affects the structure of a rock, but not its composition. It is sometimes also called mechanical weathering since it only causes mechanical changes to the rock's structure. Forces that shatter rocks, rub away rock surfaces, or form cracks within the rock are examples of physical weathering. Physical weathering does not change the chemical composition of rocks.
