Which of the following is not a type of sedimentary rock mentioned?

Granite is not classified as a sedimentary rock; it is an igneous rock. Igneous rocks, such as granite, form from the cooling and solidification of magma or lava. In contrast, sandstone, limestone, and shale are all types of sedimentary rocks that are formed through different processes involving the accumulation and compression of mineral and organic materials over time. Sandstone forms from cemented sand grains, limestone primarily consists of calcium carbonate that often originates from marine organisms, and shale results from the compaction of clay and silt particles. Understanding the classification of rocks into igneous, metamorphic, and sedimentary categories is essential in geology and helps in identifying and studying different geological formations.
