Question

What is a sedimentary arock?

Answer 1

a type of rock such as limestone

the river or sea deposits layers of sediment and rocks on the banks of the river and as layers of this build up they put weight and pressure on the lower layers. The water flow then deposits mineral cement in the rock pores which seals the layers together.

hope that helps!

Answer 2

it's a type of rock form.

Sedimentary rock is one of the three main rock groups (the others being igneous and metamorphic rock). Rock formed from sediments covers 75-80% of the Earth's land area, and includes common types such as chalk, limestone, dolomite, sandstone, conglomerate and shale

Sedimentary rocks are classified by the source of their sediments, and are produced by one or more of:

clastic rock formed from fragments broken off from parent rock, by weathering in situ or erosion by water, ice or wind, followed by transportation of sediments, often in suspension, to the place of deposition:

-biogenic activity; or

-precipitation from solution.

Sedimentary rocks are formed because of the overburden pressure as particles of sediment are deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension
