GENERAL KNOWLEDGE

Detailed explanation-1: -Reason for sedimentary rocks to be the only rock type to contain fossils: The dead plants and animals, where they are buried by more sediment results in the accumulation of minerals from water in bones which leads to formation of fossils. This makes sedimentary rocks the only rock type to contain fossils.

Detailed explanation-2: -Fossils are most commonly found in sedimentary rock among the three major rocks. Unlike most igneous and metamorphic rocks, sedimentary rocks form at temperatures and pressures that do not destroy fossil remains.

Detailed explanation-3: -Common Sedimentary Rocks: Common sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans. When buried, the sediments lose water and become cemented to form rock. Tuffaceous sandstones contain volcanic ash.
