|
Physical and chemical weathering provide extreme pressure to sediments which compact it into sedimentary rocks

|
physical and chemical weathering deposit sediments in a specific location where they are compacted into sedimentary rocks

Detailed explanation-1: -How do chemical and physical weathering contribute to the formation of sedimentary rocks? Physical and chemical weathering create sediment which is later buried and compacted into sedimentary rocks. Physical and chemical weathering move sediment from one location to another to be deposited.
Detailed explanation-2: -Erosion and weathering transform boulders and even mountains into sediments, such as sand or mud. Dissolution is a form of weathering-chemical weathering. With this process, water that is slightly acidic slowly wears away stone. These three processes create the raw materials for new, sedimentary rocks.
Detailed explanation-3: -Chemical sedimentary rocks form by chemical precipitation that begins when water traveling through rock dissolves some of the minerals. These minerals are carried away from their source and eventually redeposited, or precipitated, when the water evaporates away.
Detailed explanation-4: -Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock. The latter two steps are called lithification.
Detailed explanation-5: -Physical Weathering Bedrock is broken down through the process of weathering. Weathering is a set of physical, chemical, and biological processes that break down the bedrock into inorganic material that eventually becomes parent material for the soil.
