Introduction To Sedimentary Rock

Rock that forms when sediments are compacted and cemented together

weathering and erosion of pre-existing rocks ---- Weathering breaks down pre-existing rock into particles, while erosion moves the particles to a site of deposition. These processes begin the formation of sedimentary rock.

wind waves running water ice Sediment can be moved by wind, running water, ice, or waves.

Correct! Rock salt is a sedimentary rock that contains intergrown crystals of halite.

If the flat particles are aligned parallel in a sedimentary rock, the particles have been compacted.

Sedimentary Rock made up of rounded pebbles. a clastic sedimentary rock with large fragments in a finer-grained matrix

A fine-grained clastic rock composed of silt plus a significant component of clay, which causes it to break readily along bedding planes. A type of sedimentary rock composed primarily of clay that is compacted together by pressure.

The division of sediment or sedimentary rock into parallel layers (beds) that can be distinguished from each other by such features as chemical composition and grain size. , layering visible in rocks that results from the settling of particles during deposition

the commonest type of solidified lava

chemical weathering

Clay minerals are the resistant by-product of chemical weathering and quartz is the most resistant common mineral in Earth's crust. They are common in detrital sedimentary rocks.

limestone

A hard compact, fine-grained sedimentary rock formed almost entirely of silica. Composition-quartz Characteristics-Microcrystalline; very hard.

a common white or colorless mineral (hydrated calcium sulphate) used to make cements and plasters (especially plaster of Paris)

evaporate composition; translucent, salty taste, cubic cleavage, A rock: sedimentary, composed of halite with a find to coarse crystalline structure., naturally occurring crystalline sodium chloride

a hard kind of stone; đá lửa; viên đá lửa, the kind of hard stone that makes sparks when struck against steel

A sedimentary rock composed primarily of calcium carbonate. 10% to 15% of all sedimentary rocks are limestones. Limestone is usually organic, but it may also be inorganic. , A biochemical sedimentary rock lithified from carbonate sediments and composed mainly of calcium carbonate in the form of the mineral calcite., the most abundant chemical sedimentary rock is

Sedimentary rock that forms when rock fragments are squeezed together under high pressure

sedimentary rocks are made from broken fragments

Conglomerate is a detrital sedimentary rock that is characterized by rounded fragments that are larger than 2 mm in diameter.
