Is coal an igneous rock sedimentary rock or metamorphic rock?
Bituminous coal is consided a sedimentary rock. Anthracite coal is bituminous coal that has been metamorphosed by great pressure and heat and is considered a metamorphic rock.
What are the characteristics of the three types of rocks sedimentary metamorphic and igneous?
Sedimentary rocks: Rock formed when chemical reactions cement sediments (small, solid fragments of rocks and other materials) together, hardening them. Igneous rocks: Rock that forms from molten rock (hot magma thats cools and hardens). Metamorphic rocks: Igneous/sedimentary rock that has been changed into a new kind of rock as a result of great pressure and temperature.
What is it called when pressure changes a rock?
That is called a Metamorphic rock. it can take thousands to millions of years to create these but they can be formed pretty quickly too. for example, when a meitor hits the earths surface, it can create metamorphic rocks instantly.
If you examine a rock sample and observe fossils in it what type of rock does the sample represent?
Fossils are only found in rocks that are laid down on the surface of the Earth. The majority of fossiliferous rocks are therefore sedimentary BUT fossils are also occasionally found in lava flows (igneous rocks) - eg lava trees and in some metamorphosed sedimentary rocks (metamorphic rocks) - eg the "delabole butterfly"
What three processes occur during the formation of sedimentary rocks?
There are actually 4 processes in which a sedimentary rock forms. 1) Erosion. A process in which old rock wear away and become sediment. 2) Deposition. When the sediment is deposited somewhere and are loosely packed. 3) Compaction. A process in which the sediment particles are squeezed under great pressure. 4) Cementation. When the particles are "glued" together forming 1 rock.
How can sedimentary rock become metamorphic?
Heating and pressure
Can metamorphic rock become sedimentary rock?
by heat and very great pressure
How can metamorphic and igneous rocks change into sedimentary rocks?
By them being boroken down (sediment) then exposed to great pressure.
How can igneous and metamorphic rocks change into sedimentary rocks?
By them being boroken down (sediment) then exposed to great pressure.
How does sedimentry change into metamorphic?
Sedimentary rocks change under great pressure and temperature condition to form metamorphic rocks
Can sedimentary rocks and igneous rocks change into metamorphic rocks?
By them being boroken down (sediment) then exposed to great pressure.
What are the two sources of the heat and pressure that cause metamorphism?
Magmatic intrusionsBurial to great depth by sedimentary overburdenPlate tectonic collision
How does sedimantary rock change into metamorphic rock?
When the sedimentary rock gets pressed with great pressure, it'll turn to metamorphic rock. Also, heating of the sedimentary rock by igneous intrusions will metamorphose it.
Why are fossils most likely to be found in sedimentary rock samples?
Most fossils are found in sedimentary rock, because igneous and metamorphic rock undergo great heat and pressure when forming, where as sedimentary rocks undergo much less pressure and heat to form, better preserving the fossil
Is coal an igneous rock sedimentary rock or metamorphic rock?
Bituminous coal is consided a sedimentary rock. Anthracite coal is bituminous coal that has been metamorphosed by great pressure and heat and is considered a metamorphic rock.
How a sedimentary rock or igneous rock become a metamorphic rock?
when sedimentary rocks get exposed to great heat and pressure, they become more consolidated (harder to weather). when igneous rock combines with sediments and the two are heated under pressure, they become one rock, a metamorphic rock
How you Convert a sedimentary rock layer into a metamorphic rock layer?
Subject it to great pressure (as from sediments or lava flows over the top of it) or great heat (but not enough to melt it), or both.
