Question

How mechanically sedimentry rocks arw formed ? tell me correct answer i will mark him brainliest​

Answer 1

Mechanically formed sedimentary rocks are primarily formed by physical factors while the chemically formed sedimentary rocks are formed due to chemical weathering. Mechanically formed sedimentary rocks are generally break up residues of metamorphic and igneous rocks

Answer 2

Explanation:

Sedimentary rocks are formed on or near the Earth’s surface. 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. 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.Precipitation and lithification are processes that build new rocks or minerals. Precipitation is the formation of rocks and minerals from chemicals that precipitate from water. For example, as a lake dries up over many thousands of years, it leaves behind mineral deposits; this is what happened in California’s Death Valley. Finally, lithification is the process by which clay, sand, and other sediments on the bottom of the ocean or other bodies of water are slowly compacted into rocks from the weight of overlying sediments.
