Detailed explanation-1: -Common sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans.
Detailed explanation-2: -Clastic sedimentary rocks are made of sediments. The sediments differ in size. Chemical sedimentary rocks are made of minerals that precipitate from saline water. Organic sedimentary rocks are made from the bodies of organisms.
Detailed explanation-3: -The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification.
Detailed explanation-4: -Types of Sedimentary Rocks The sedimentary rocks are classified into three different types: Organic, Clastic and Chemical Sedimentary Rocks.
Detailed explanation-5: -The classification in the main types (sandstone, siltstone, and claystone) follows the grain size classification for clastic sediments (Fig. 1.3).
