4.8: Sedimentary Rocks
Sedimentary rocks formed by the crystallization of chemical precipitates are called chemical sedimentary rocks. Biochemical sedimentary rocks form in the ocean or a salt lake. Living creatures remove ions, such as calcium, magnesium, and potassium, from the water to make shells or soft tissue. When the organism dies, it sinks to the ocean floor ...

Introduction. The Earth's crust is a dynamic system that has evolved over millions of years, giving rise to different types of rocks. These rocks—sedimentary, igneous, and metamorphic—form the foundation of Earth's geology and hold clues to its past.Each rock type is defined by its formation process, composition, and texture, which are directly related to the …

10 Things To Know About Sedimentary Rocks
Sedimentary rocks are divided into three basic types based on their origin and composition: clastic, chemical, and natural. Clastic sedimentary rocks are formed by the accumulation and cementation of rock and mineral fragments, or clasts, transported and deposited by wind, water, or ice.

Sedimentary rocks contain information about what was occurring on earth's surface at the place and time the sediments were deposited. In some cases sedimentary rocks contain fossils, which provide information about what was living at a certain place and time on earth.

Sedimentary Rocks
They are also called detrital sedimentary rocks and are formed from pieces of preexisting rocks loosed by weathering. The loosened rocks are then transported to some depression where the sediments are trapped. If it is buried deep, it becomes compacted and cemented, forming sedimentary rock.

Introduction to Rocks
There are two major groups of sedimentary rocks: 1) siliciclastic and 2) chemical and organic. Visible layering is common in sedimentary rocks. Most fossils are found in sedimentary rocks; exceptions are specimens found in metamorphic rocks that were once sedimentary (e.g., fossil shells in marble) or those found in ice (e.g., remains of mammoths).
