What two processes play a role in forming sedimentary rocks?

Answer 1

The process of lithification changes rocks into sediments. This process is broken up into two parts: cementation and compaction. In cementation, the substance crystallizes, or fills in the spaces between loose particles of sediment. In compaction, the sediments are squeezed together by the weight of layers on top of them.

Answer 2

First, sediments are eroded into a large body of water (lake or ocean). Then the sediments are deposited to the bottom of the lake or ocean. As layer on layer compile, the lower layer gets compacted. Finally the minerals in the sediments dissolve and cement the sediments together, making sedimentary rock. - nirmal

Answer 3

When sediments are deposited in a depositional environment such as lakes,streams,swamps,oceans,deltas etc. The water source will eventually dry up and the sediments will become compacted and cemented together over a long period of time.

Answer 4

I may not be able to mention the two processes but i hope this helps.

- Sedimentary rocks are formed from sediments. They are mostly formed under water in the lakes, seas, and river deltas. Sand and mad settle at the bottom of the sea forming a layer of sediment. The layers of sediment build up a year after a year until they are very thick. The weight of the upper layers of sediment and the water above press on the lower layers, causing the particles of sediment to stick together forming a sedimentary rock.

- Limestone is a sedimentary rock formed from the shells of tiny plants and animals that lived in the sea million years ago. Shale is another example of a sedimentary rock. It is formed from clay particles.

- Sedimentary rocks are soft and porous. They are usually built in layers called "Strata." Fossils are also found in many sedimentary rocks.

Answer 5

Sediment, such as sand, is crushed by enormous force and heated to a high temperature before the grains "bond" together.

Answer 6

the sea erodes away sediments of rock and the sediments lay on the sea floor, after time the weight of the sediments pushes the water out and forms sedimentary rock.

Answer 7

1: compaction

2: cementation

Answer 8

Compaction and cementation
