Rocks become weathered through a combination of physical and chemical processes. Physical weathering occurs when rocks are broken down into smaller pieces by forces such as wind, water, and temperature changes. Chemical weathering happens when the minerals in rocks react with substances like water and oxygen, leading to their breakdown and dissolution. Over time, these processes can cause rocks to wear away and change their appearance.
Weathered rocks that are composed of smaller fragments and grains are referred to as sedimentary rocks. These rocks are formed through the process of erosion, transportation, deposition, and lithification of the weathered materials.
Sedimentary rocks made of weathered rock fragments are called clastic sedimentary rocks. These rocks are formed from the accumulation and cementation of fragments that have been weathered, eroded, and transported from their original source. Examples include sandstone, shale, and conglomerate.
Sediment is formed when rocks are eroded or weathered in water. When the process occurs on land, the smaller pieces of rock mix with organic matter (plant, animal or spoor), and eventually become soil.
Sedimentary rock
Detrital sedimentary rocks are made from weathered rocks.
Neither, at the surface all rocks become weathered.
Sedimentary rocks can be both chemically and mechanically weathered.
The layer of soil that contains weathered rocks is the subsoil. This layer is located beneath the topsoil and consists of partially weathered rocks and minerals.

Some weathered rocks have rust streaks due to the iron content in the rocks. When rocks that have ferrous iron are weathered there will be rust streaks present.
NO
Soil is a mixture of organic matter and weathered rocks. Organic matter comes from decomposed plant and animal material, while weathered rocks contribute minerals and nutrients to the soil.
When sedimentary rocks are weathered and eroded, they turn into sediments. And after compaction and cementation of the sediments, it will turn back into sedimentary rock.
No. Metamorphic rock are simply rocks which have been altered by heat and pressure.
We get weathered by being on or near the surface and exposed to environments different than we were formed in.
Rocks that are subjected to weathering and erosion at the Earth's surface eventually become sedimentary rocks. These rocks form from the accumulation and cementation of sediments such as sand, silt, and clay that have been weathered and eroded from pre-existing rocks.
