Chemical and physical weathering both involve the breakdown of rocks into smaller particles. Both processes are influenced by factors like temperature, moisture, and the type of rock being weathered. Additionally, both types of weathering contribute to soil formation by breaking down rocks into mineral particles.
Chemical weathering involves the breakdown of rocks through chemical reactions, such as oxidation or dissolution. Physical weathering, on the other hand, occurs when rocks are broken down into smaller pieces through physical processes like freezing and thawing, or abrasion. Chemical weathering changes the composition of the rock, while physical weathering only breaks the rock into smaller pieces.
Mechanical weathering is the breakdown of rocks into smaller pieces without altering their chemical composition, usually by processes such as frost wedging or root expansion. Chemical weathering, on the other hand, involves changes in the chemical composition of rocks due to reactions with substances like water, acid rain, or oxygen, leading to the breakdown of minerals.
A chemical change results in the formation of new substances with different chemical properties, while a physical change involves a change in appearance, state, or form of a substance without altering its chemical composition. Chemical changes are usually irreversible, while physical changes can often be reversed.
Oxidation is the recombination of atoms of one molecule with oxygen. An example might be the rusting of iron: 2Fe(s) + 3O2(g) --> 2Fe2O3(s) Therefore, oxidation is chemical reaction.
Physical change, changes the appearance or the surface. Chemical change, changes the minerals inside the object. Physical deals with the appearance and the surface. Chemical changes the structure of the minerals inside the object.
Physical weathering is breaking down of rocks by weather that does not change their chemical components. Chemical weathering is weathering that breaks rocks down by a chemical change.
physical weathering is weathering that you can reverse and chemical weathering is where you can' reverse it.
physical: water, wind, and temperature chemical: acid rain and rust
The principal difference between weathering and chemical weathering is that weathering involves physical processes that break down rocks into smaller pieces without changing their chemical composition, while chemical weathering involves chemical reactions that alter the mineral composition of rocks.
Physical weathering involves the breakdown of rocks into smaller pieces without changing their chemical composition, while chemical weathering involves the alteration of rocks through chemical reactions. Acid rain is a form of chemical weathering, as it can react with rocks and minerals to degrade them.
Chemical weathering involves the breakdown of rocks through chemical reactions, such as oxidation or dissolution. Physical weathering, on the other hand, occurs when rocks are broken down into smaller pieces through physical processes like freezing and thawing, or abrasion. Chemical weathering changes the composition of the rock, while physical weathering only breaks the rock into smaller pieces.
Similarities: Both processes result in the breakdown of rocks and minerals. Both can occur through natural processes like temperature changes, water, and biological activity. Differences: Physical weathering involves the physical breakdown of rocks into smaller pieces without changing their chemical composition, while chemical weathering alters the chemical composition of rocks through reactions with substances like water or acids. Physical weathering does not involve chemical reactions, while chemical weathering does.
Physical weathering involves the breakdown of rocks into smaller fragments without altering their chemical composition, typically through processes like freezing and thawing or abrasion. Chemical weathering, on the other hand, involves the decomposition of rocks through chemical reactions that change their composition, such as oxidation or dissolution by acidic water. Both processes contribute to the overall breakdown of rocks, with physical weathering primarily affecting the size and shape of rocks, and chemical weathering changing their chemical structure.
they both break down stuff into fragments.p.s : this is the right answer.
Physical weathering involves the breakdown of rocks into smaller pieces without changing their chemical composition, such as through freeze-thaw cycles or abrasion. Chemical weathering, on the other hand, alters the chemical composition of rocks through processes like oxidation or hydration, leading to the formation of new minerals.
Physical or mechanical weathering is caused by processes like frost wedging, root wedging, and abrasion, where physical forces break down rocks into smaller pieces. Chemical weathering, on the other hand, is caused by chemical reactions between rock minerals and substances in water or in the atmosphere, leading to the alteration or dissolution of the rock. Temperature changes, presence of water, oxygen, and acids are common factors that contribute to chemical weathering.
Similarities: Both physical and chemical weathering processes break down rocks. They can both be influenced by factors such as temperature, moisture, and the type of rock. Differences: Physical weathering involves the mechanical breakdown of rocks into smaller pieces without changing their chemical composition. Chemical weathering, on the other hand, involves the alteration of rock composition through chemical reactions with water, gases, or other substances.
