Sedimentary rocks: Are formed by the accumulation of

Sedimentary rocks are formed by the accumulation of sediments. There are three basic types of sedimentary rocks .

Sedimentary rocks are one of three main types of rocks , along with igneous and metamorphic. They are formed on or near the Earth’s surface from the compression of ocean sediments or other processes. Learn about the three types of rocks : igneous, sedimentary , and metamorphic. Learn their characteristics and get examples of each type. Sedimentary rock, rock formed at or near Earth’s surface by the accumulation and lithification of sediment or by the precipitation from solution at normal surface temperatures.
