Sedimentary Rock: Types and How They Are Formed? | Rocks ...

Types of Sedimentary Rock. There are three major types of sedimentary rocks; chemical, clastic and organic sedimentary rocks. 1. Chemical. Chemical sedimentary rocks occur when components of water evaporate and previously dissolved minerals are left behind. These types of sedimentary rocks usually occur in arid areas; like gypsum and salt deposits.

Sedimentary Rock Examples

Sedimentary rocks make up most of the rocks on the earth and are formed when bits of rock, soil or organic matter settles and accumulates. Plant and animal fossils can be found in sedimentary rock. When there is an abundance of plants and animals, fossil fuels develop, like oil, natural gas and coal.
