Why do rock fossils form in sedimentary rock and not in igneous rock-?
Fossils are formed in sedimentary rock because the rock is formed at temperatures that do not destroy the fossils like the igneous rocks would.
How does metamorphic form?
Metamorphic rock is formed by heat and pressure making changes to igneous and sedimentary rock.
Is anthracite an igneous metamorphic or sedimentary?
Anthracite is a metamorphic rock. Anthracite is formed when an organic sedimentary rock - coal - is compressed and heated in the ground.
How are rocks classified into one of these three groups?
Rocks are classified into three groups based on how they are formed. Igneous rock is formed when magma cools and crystallizes. Sedimentary rock is formed when the products of weathering and erosion are compacted and cemented to form new rock. Metamorphic rock is formed when existing rock is changed by heat, pressure or chemical change into a new kind of rock.
How are sedimentary metamorphic and igneous formed?
metamorphic - formed when igneous or sedimentary rocks are put under extreme heat and/or pressure. igneous - volcanic rock (comes from a volcano) sedimentary - particles of rock/sand/shells/clay etc. 'gathered' to make a rock.
Is uvite formed by sedimentary metamorphic or igneous?
metamorphic
What are the three types of rock and their formation?
there are 4 bill bob and jerry and the one in abi's head she likes to call a brain Igneous, Sedimentary, and Metamorphic.
Name the 3 kinds of rocks?
There are three major types of rock: igneous (formed from the cooling and solidification of magma or lava) sedimentary (laid down as sediments) and metamorphic (changed by heat and/or pressure)
Why do rock fossils form in sedimentary rock and not in igneous rock-?
Fossils are formed in sedimentary rock because the rock is formed at temperatures that do not destroy the fossils like the igneous rocks would.
What types of stones are most likely to contain fossils?
There are three basic types of rock; sedimentary, igneous and metamorphic. Igneous rocks are formed by volcanic action and don't contain fossils. Sedimentary rocks are formed, usually under water, by eroded material accumulating. Metamorphic rocks are formed when sedimentary rocks are changed by heating and/or pressure. From this, you can see that sedimentary rocks are the most likely to contain fossils, although metamorphic rocks also can contain fossils. Any sedimentary rock can contain fossils, but some make fossil hunting easier. Shales and mudstones are particularly good; chalk is pretty much entirely made of fossils - it's formed of skeletons of small organisms, but its difficult to see the individual fossils.
Is a meta conglomerate a metamorphic igneous or a sedimentary?
It is a metamorphic rock formed from a progenitor sedimentary rock called a "conglomerate".
How do we classify rocks as igneous and sedimentary and metamorphic?
composition, how it is formed
Can metamorphic rocks be formed from changes in igneous sedimentary or other metamorphic rocks?
yes
Name the three major groups of rocks and describe how each forms?
The three groups are igneous, sedimentary, and metamorphic. igneous forms when magma or lava cools down. sedimentary forms when sediments (clay, sand, silt etc) gets compressed. and metamorphic forms when an igneous or sedimentary goes under very high temperatures and pressure
How are metamorphic and sedimentary igneous rocks formed?
Igneous- Formed from hot molten magmaSedimentary- formed from sediments piling up creating layersMetamorphic- Formed when intense heat AND pressure are applied to an igneous or sedimentary rock.
How does metamorphic form?
Metamorphic rock is formed by heat and pressure making changes to igneous and sedimentary rock.
Is anthracite an igneous metamorphic or sedimentary?
Anthracite is a metamorphic rock. Anthracite is formed when an organic sedimentary rock - coal - is compressed and heated in the ground.
