What Are Examples of 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.

What Are Examples of Sedimentary Rocks?

Sedimentary rocks are rocks that are formed by the deposition of sediments. The sediments can be deposits of minerals, rocks, or organic matter.

The sediments can be deposited by wind, water, ice, or gravity. Sedimentary rocks are classified into three main types: clastic sedimentary rocks, chemical sedimentary rocks, and organic sedimentary rocks.

Clastic sedimentary rocks are rocks that are made up of fragments of other rocks. The fragments can be any size, from sand grains to boulders.

The most common clastic sedimentary rocks are sandstone, shale, and conglomerate. Chemical sedimentary rocks are rocks that are formed by the precipitation of minerals from solution.

The most common chemical sedimentary rocks are limestone and dolomite. Organic sedimentary rocks are rocks that are formed from the remains of plants or animals.

The most common organic sedimentary rocks are coal and oil shale. Sedimentary rocks are important because they are the rocks that make up the majority of the Earth‘s crust. They are also important because they contain a lot of information about the Earth‘s history.
