GEOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Chemical sedimentary rocks can be found in many places, from the ocean to deserts to caves. For instance, most limestone forms at the bottom of the ocean from the precipitation of calcium carbonate and the remains of marine animals with shells.

Detailed explanation-3: -Most sedimentary rocks, therefore, form in the ocean, or in lakes, or as gravel and clay accumulations in the flood plains of rivers, which become buried by later clay and gravel deposits until they are deeply buried enough to become lithified.

Detailed explanation-4: -Which of the following is true about sedimentary rocks? They cover up to 50% of Earth’s land areas. They form from mechanical, but not chemical weathering.
