What are the steps needed to form metamorphic rock from magma?
Metamorphic rock is not formed directly from magma. Igneous rock is formed from the solidification of magma and lava.
What M describes rocks that were formed when existing rocks were heated or squashed?
Metamorphic rock. This can naturally form an existing Sedimentary, Igneous or Metamorphic rock due to exposure to heat and/or pressure.
What is the term when rocks are formed when older rocks are heated or squeezed?
If it is squeezed and heated sufficiently to realign the minerals or form new minerals, it is called a metamorphic rock. If it is squeezed and heated enough to melt, then solidify, it would be called an igneous 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.
Metamorphic rocks can only be formed from?
Well, metamorphic rocks can be formed from sedimentary rock OR igneous rock OR other metamorphic rock that has been pushed far beneath the crust of the earth.

How is a anthracite coal formed?
anthracite coal is the metamorphic form of bituminous coal which is the sedimentary form. in other words it has been heated under pressure.
How is anthracite coal formed?
anthracite coal is the metamorphic form of bituminous coal which is the sedimentary form. in other words it has been heated under pressure.
What rocks are formed from high temperature and pressures?
Igneous, metamorphic, and sedimentary rocks can be changed by high temperatures and pressure, and the resultant rock is called metamorphic, because its form has been changed.
What kind of metamorphic rock is formed where rocks have been heated but not deformed?
a rock with metamorphic minerals but no foliation or lineation
What is the major difference between igneous and metamorphic rocks?
igneous rocks started as melted lava and cooled to be rocks. Metamorphic rock started as a sedimentary rock, and was heated up and put under pressure to create the metamorphic rock. Classic example - igneous = obsidian. Metamorphic = marble (marble is limestone that's been heated and squeezed a lot).
The most common charactristic of metamorphic rock is?
The only real characteristic that metamorphic rocks share is that they are formed by heat and pressure. Granite warps and twists and becomes schist; shale is compressed and heated and becomes slate... etc.
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 does marble and other metamorphic rock from?
Marble is formed from limestone being buried, heated and subjected to pressure, causing minerals to recrystallise into different atomic structures, forming different minerals to the original limestone. In laymans terms this is the process that occurs to form all metamorphic rocks. The type of metamorphic rock formed is dependant on the chemical and mineral composition of the source rock, and the amount of heat and pressure the source rock is subjected to.
