What is the or-gin of sedimentary rocks?
weathering of preexisting rocks form clastic sedimentary rocks, Oversaturated water basins form chemical sedimentary rocks after the water evaporates and dead sea organisms settle at the bottom forming biochemical sedimentary rocks.
What are sedimentary rocks made of?
Sedimentary rocks can be made from any kind of material, from other rocks to shells to plant material. Basically, any rock, from metamorphic to igneous and even to sedimentary, can be weathered and eroded. These particles and grains can be carried great distances by wind, water, ice, etc. before they are deposited and lithified (cemented) back together to form sedimentary rocks.
Three ways in which sedimentary rocks differ from other rocks?
Sedimentary rocks are made up of materials that were once part of another rock. Most sediments are deposited on ocean floors or at the bottom of rivers and lakes.Clastic sedimentary rocks form from layers of sediments. Pressure causes the water around the sediments to be squeezed out and the sediments are cemented together.
What are the four major processes that form sedimentary rocks?
wind water ice gravity
Do igenous rocks have layers called strata?
Yes, Sedimentary rock is a type of rock that is formed by sedimentation of material at the Earth's surface and within bodies of water. Sedimentation is the collective name for processes that cause mineral and/or organic particles (detritus) to settle and accumulate or minerals to precipitate from a solution. Particles that form a sedimentary rock by accumulating are called sediment. Before being deposited, sediment was formed by weathering and erosion in a source area, and then transported to the place of deposition by water, wind, mass movement or glaciers which are called agents of denudation. The sedimentary rock cover of the continents of the Earth's crust is extensive, but the total contribution of sedimentary rocks is estimated to be only 5% of the total volume of the crust. Sedimentary rocks are only a thin veneer over a crust consisting mainly of igneous and metamorphic rock. Sedimentary rocks are deposited in layers as strata, forming a structure called bedding. The study of sedimentary rocks and rock strata provides information about the subsurface that is useful for civil engineering, for example in the construction of roads, houses, tunnels, canals or other constructions. Sedimentary rocks are also important sources of natural resources like coal, fossil fuels, drinking water or ores. The study of the sequence of sedimentary rock strata is the main source for scientific knowledge about the Earth's history, including palaeogeography, paleoclimatology and the history of life. The scientific discipline that studies the properties and origin of sedimentary rocks is called sedimentology. Sedimentology is both part of geology and physical geography and overlaps partly with other disciplines in the Earth sciences, such as pedology, geomorphology, geochemistry or structural geology.

What force is needed when forming sedimentary rocks?
Geo-thermal force is needed in forming the sedimentary rocks. The fragments of igneous rocks by erosion are carried by water currents and deposited in the basin for millions of years. The upheaval in the earth strata bring these deposits deep. The pressure of earth mass and its heat converts these deposits in to sedimentary rocks. The red sand stone is the best example of sedimentary rock formation.
What does sedimentary rocks have to do with water?
What do sedimentry rocks have to do with water
Are sedimentary rocks being formed right now?
Yes, sedimentary rocks are being formed right now. Sediment is continually being deposited by erosion and transported by wind, water, and ice. Over time, these sediments are compacted and cemented together to form new layers of sedimentary rock.
What role does wind and water play for sedimentary rocks?
weathering and erosion helps to build sedimentary layers then sedimentary rocks
Chemocal sedimentary rocks are made from?
Chemical sedimentary rocks are formed by the precipitation of minerals from water.
Rocks formed from sediments deposits?
Sedimentary rocks are formed from sediment deposits (gravel, sand, silt, clay) over long periods of time either on land or in water (lakes, oceans). As more and more sedimentary layers are deposited, the newer layers exert pressure on the older layers, which compacts the loose particles and cements them together - forming sedimentary rocks. Sedimentary rocks can also be formed through the precipitation of dissolved minerals to form limestone or dolomite.
Are sedimentary rocks made in water?
Sedimentary rocks are usually formed in water, but not always. Some sandstones, for example, form in deserts.
What rock forms from evaporation of water?
Chemical sedimentary rocks
The orgin of sedimentary rocks?
Sedimentary rocks come from the deposition of material at the Earth's surface and within bodies of water.
Crystalline sedimentary rocks?
All sedimentary rocks are made by of deposition of the products of erosion either on land or more usually in water. Crystalline sedimentary rocks can be produced by the evaporation of a brine.
Sedimentary rocks form when layers of small particles are compressed?
The small particles are compressed under water to then form sedimentary rocks
