GEOLOGY

Detailed explanation-1: -Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.

Detailed explanation-2: -Mechanical weathering (also called physical weathering) breaks rock into smaller pieces. These smaller pieces are just like the bigger rock, just smaller. That means the rock has changed physically without changing its composition.

Detailed explanation-3: -Answer. Answer: Mechanical weathering breaks rocks into smaller pieces without changing their composition. Ice wedging and abrasion are two important processes of mechanical weathering.

Detailed explanation-4: -These broken pieces of rock are called sediments. The word “Sedimentary” comes from the root word “Sediment". Sedimentary rocks are usually formed in water. Streams and rivers carry sediments in their current.

Detailed explanation-5: -Erosion and weathering include the effects of wind and rain, which slowly break down large rocks into smaller ones. Erosion and weathering transform boulders and even mountains into sediments, such as sand or mud.
