Detailed explanation-1: -Sedimentary rocks are formed from pieces of other existing rock or organic material. There are three different types of sedimentary rocks: clastic, organic (biological), and chemical.

Detailed explanation-2: -Sedimentary rocks are formed by the lithification of inorganic and/or organic sediments, or as chemical precipitates. Clastic sedimentary rocks form when existing parent rock material is weathered, fragmented, transported, and deposited in layers that compact, cement, and lithify to form sedimentary rocks.

Detailed explanation-3: -Scientists define rock as a naturally occurring solid mixture of one or more minerals that may also include organic matter. Most rock is made of minerals, but some rock is made of nonmineral material that is not organic, such as glass. Rock has been an important natural resource as long as humans have existed.

Detailed explanation-4: -Igneous, Sedimentary, and Metamorphic A rock is a naturally occurring aggregate of minerals, and certain non-mineral materials such as fossils and glass.

Detailed explanation-5: -Rock is a solid mixture of crystals of one or more minerals, or organic matter.
