metamorphoc rock

Metamorphic rocks are formed by

• Weathering

• Heat and pressure

• Magma

Metamorphic rocks start with

• Magma

• Sediment

• Preexisting rock

What is metamorphism?

• Change in form

• Changing Rocks

• Change in temperature

Rocks become warped and deformed and can be forced to

• Break apart and settle

• Melt

• Compact into smaller spaces

When the rocks are compacted what is happening?

• They are changing shape

• They are changing color

• They are chemically and physically changing

Because if the intense pressure, metamorphic rocks tend to _______

• Have more crystals

• Be more dense

• Be heavier

Which type of rock can become metamorphic?

• Igneous

• Sedimentary

• Metamorphic

• All of the above

When Rocks are buried deep deep in the earth at high temperatures and pressure

• Melting occurs and igneous rocks are formed

• They form sedimentary rocks

• They firm new me minerals as long as there’s no melting.

If melting does occur?

• The rock cycle starts over again

• Metamorphic rocks are formed

• Quartz is formed

When sandstone is changed under heat and pressure it turns into

• Quartzite

• Pyrite

• Pumice
