Detailed explanation-1: -The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification. Erosion and weathering include the effects of wind and rain, which slowly break down large rocks into smaller ones.
Detailed explanation-2: -Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock. Clastic sedimentary rocks may have particles ranging in size from microscopic clay to huge boulders.
Detailed explanation-3: -Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological detritus (organic matter).
Detailed explanation-4: -Stratification The most important feature of sedimentary rock is stratification. Stratification is the process in which sedimentary rocks are arranged in layers.
Detailed explanation-5: -Erosion. Erosion is the process where rocks are broken down by natural forces such as wind or water. There are two main types of erosion: chemical and physical. Chemical erosion occurs when a rock’s chemical composition changes, such as when iron rusts or when limestone dissolves due to carbonation.
