Sediments harden to form sedimentary rock through the application of pressure. Heat may play a part, but it is the settling down of the sediment and the buildup of overburden that "crushes" the material together. After millenia in a "big squeeze" applied by zillions of tons of material that has been superpositioned, sedimentary rock if formed. A link can be found below to the Wikipedia post on sediment and on sedimentary rock.

∙ 13y agoAs rivers flow to the sea, they may carry mud, sand, pebbles, and boulders along the way. The river drops this material, called sediment, into the sea. As layers of sediment build up over a period of many years, the great pressure of all these layers changes the sediment into sedimentary rock.
Many different types of sedimentary rock can be formed, depending on the material that is found in the sediment. If the layer of sediment contains large amounts of sand, what kind of rock do you think will be formed? Of course, it will be sandstone.

Weathering from mechanical and chemical means is the process that causes rocks to become smaller and smaller; wind, rain, the sun, the freeze/thaw cycle, moving glaciers, chemical reactions, and gravity.

Describe the process by which most fossils form?
1. An ancient animal dies and sinks to the bottom of a river 2. Layers of sediments cover the animal's body 3.Over millions of years, the sediment harden to become rock. The animal is preserved as a fossil. 4. The rock erodes. The fossil is exposed on the surface of a rock.
Where are most the fossil preserved?
The best place to find dinosaur fossils in the world is in the United States. Another place to find dinosaur fossils is in Alberta, Canada. The best place to look for fossils is somewhere where there aren't many plants/trees, like a desert.
What three elements are likely to be found in a sample of soil and rocks?
soil- Clayey soil, sandy soil, and loamy soil rock-metamorphic rock, instrusive/extrusive rock, sediments
What sedimentary rock is made of large angular pieces of sediments?
Breccia.
What does rock cementation mean?
Cementation is part of the process of lithification of sediments, or particles of rock, that form sedimentary rock. Cementation takes place as water is squeezed out by pressures on the sediments exerted by the weight of overlying sediments. The water is replaced by minerals such as carbonates, silicates, iron oxides, or clays, which bond the sediment particles together into a sedimentary rock.
What is made when sediments fill in a cavity made when an object decayed and the sediments harden into rock?
Cast.
What can form fossils before sediments harden into rock?
Coral reef.
What type of rock forms when sediments are cemented together and harden?
Sedimentary Rock Not Igneous or Metamorphic Rock
What a type of rock formed when sediments harden and are cemented together?
sedimentary, obviously
How does metamorphic rock turn into another type of rock?
It can be worn down to create sediments that become seidmentary rock, or it can melt and harden to form igneous rock.
How does rock fragments turn into rock?
Rock fragments are called sediments and by a process called lithification they turn into sedimentary rocks. Lithification is made up by compaction and cementation which is by pressure and a natural glue that is formed from groundwater the sediments stick together and then harden into rock.
What is the process by which sediments are pushed together in layers to form sedimentary rock?
Settlement and compaction. As particles (sediments) are dumped, lets say, at the bottom of a lake, they will begin to settle and eventually harden into a sedimentary rock.
What is a rock and how it is form?
A sedimentary rock is formed from sediments, that is particles of preexisting rocks that have been broken down by weathering process and transported to new locations by water, ice or wind. The sediments accumulate over time as layers deposited parallel to the Earth's surface and, as they become buried by overlying deposits, they harden to form rock - sedimentary rock. During their deposition process, they may include burrows, shells or bones of living creatures and these become fossils as the sediments harden.

How sediments can become igneous rock?
The sedimentary rock melts,which causes magma. When the magma cools it becomes an igneous rock.
What type of rock forms a fossil?
sedimentary rock -sedimentary rock because organisms die on land or on the bottom of a body of water and the sediments cover it and harden to form fossils. -also, limestone can form fossils.
Why does the river have so many more rocks then the ocean?
it has more rocks because the river has lots of sediments ( pieces of broken rock ) to carry along the river flow. then the sediments pile up into layers and then for many years the layers will harden and turn into a rock. YOUR WELCOME :)
