What is the composition of a rock depends on?
For igneous rocks,the composition depends on the source magma,either basaltic or granitic,For Sedimentary rocks it depends on source of sediments or nature of salts which existed in the basin from which precipitation took place, and for metamorphic rocks it depends upon the source rock.
Where do most sedimentary rocks end up?
Through the processes of weathering (breaking of rocks into smaller pieces) and erosion (transport of material from one place to another by ice, wind, water, and gravity), or by the transport or exposure of sedimentary rock by tectonic forces, such as plate movements. ( i have edited the answers completely as the last idiot said under my meat)
What three factors can change a sedimentary into a metamorphic rock?
heat,pressure,&chemically active fluids
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.
How long does it take to form a metamorphic rock?
Metamorphism can be instantaneous as in the shearing of rocks at plate boundaries or can take millions of years as in the slow cooling of magma buried deep under the surface of the Earth. But on other hand metamorphism can be made in labs in one minute but certain chemical
How does sedimentary rock become igneous?
If sedimentary rock is melted, then solidifies from melt, it is now an igneous rock. This can occur from contact with an intruding body of magma, or from heat and pressure from deep burial or collisions between plates and orogenic processes, where the sedimentary rock is first metamorphosed before melting.
What process must take place to change igneous or sedimentary rock to metamorphic rock?
Heat and pressure
What are two major processes that form sedimentary rock?
Sedimentary rocks require two processes to be formed. The first is weathering. Weathering is the disintegration/decomposition of rocks. Erosion is the process by which the weathered material is moved from one place to another. Erosion occurs when, for instance, a moving stream picks up a weathered pebble and moves it miles downstream to the mouth of a river. Erosion can also take place with ice, wind, etc.
Using the rock cycle what has to happen for an igneous rock turn into a sedimentary rock?
An igneous rock would need to weather and erode, the sediments transported by wind, water, ice, or gravity to a place of deposition where they would undergo compaction and cementation, thus creating a sedimentary rock.
Which physical change takes place when an igneous rock turns into a sedimentary rock?
Erosion, transportation of the eroded material, deposition of this material then lithification.

What process must take place to change igneous or metamorphic rock to sedimentary rock?
All rocks on Earth take part in the "Rock Cycle". For an igneous or metamorphic rock to change into a sedimentary rock, they must undergo weathering and erosion by wind, water, and/or ice. The broken down pieces of rock (sediments) settle into layers that form a sedimentary rock.
What are the names for the three type of rocks?
Igneous, Sedimentary, Metamorphic. Igneous rocks are made of solidified magma. Sedimentary rocks are those that are made by the weathering or erosion of soil of Earth. Metamorphic rocks are when rocks are changed from one material to another; new minerals are created.
What results when rocks come in contact with molten rocks such as those in an igneous intrustion?
If sedimentary rock becomes intruded by a mass of magma in an igneous intrusion, it will turn into a metamorphic rock. The change takes place because of great pressure and intense heat.
How can a rock be made of igneous and sedimentary components at the same time?
Different source areas came together in one place. Still considered sedimentary, because it's composed of sediments. Doesn't matter what the composition is, could be metamorphic in there too.
How does igneous rock turn into sediment Rock?
Through weathering and erosion of the igneous rock. The igneous rock, exposed to weathering processes at the surface, breaks into smaller pieces. Erosional processes transport these pieces to a place of deposition where they build up, layer on layer. Eventually the compaction caused by the weight of the sediments above reduces the amount of space and water between particles. In this process of rock formation known as lithification, cementing minerals are formed out of the slowly disappearing fluids, which are saturated with mineral components. Once cemented together, it is now considered sedimentary rock. Quartz sandstone is an example of the resultant sedimentary rock derived from the processes described above on the igneous rock granite.weathering errosion transportation deposition and finally cementation converts to sedimentary rock
Explain how igneous rocks change into sedimentary rocks and metamorphic rocks?
Igneous to sedimentary: Igneous rock becomes exposed at the surface. Weathering of the rock occurs and the rock is broken down into smaller and smaller particles. The particles are transported and deposited by rain, wind, gravity, or ice to a place of deposition, where they eventually lithify through compaction and cementation into a sedimentary rock.Igneous to metamorphic: An igneous rock body is exposed to heat and pressures from tectonic plate collisions. The directional stress imposed on the rock causes the constituent minerals to align themselves perpendicularly to the direction of the stress and some recrystallization may occur, creating a banded or foliated metamorphic rock.
