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.
What else can I help you with?
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
What occurs when substances harden crystallize in the spaces between loose sediments?
When substances harden and crystallize in the spaces between loose sediments, they form a type of rock called a crystalline sedimentary rock. This process involves the filling of pore spaces with mineral crystals, which bind the sediments together to create a solid rock matrix. Common examples of crystalline sedimentary rocks include limestone and dolomite.
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 :)
What is the process by which sediments are pushed together in layers to form sedimentary rock?
The process by which sediments are pushed together in layers to form sedimentary rock is called lithification. This involves compaction, where the weight of the overlying sediments squeezes out water and air between grains, and cementation, where minerals in groundwater precipitate and bind the sediments together. Over time, these processes create solid sedimentary rock layers.
How is sedimentary rock formed through the process of making sedimentary rock?
Sedimentary rock is formed when sediments, like sand or mud, are compacted and cemented together over time. This process, called lithification, occurs when layers of sediment accumulate and are gradually pressed together by the weight of overlying material. Eventually, the sediments harden into rock through the binding of minerals and other materials.
