Metamorphic Rocks Quiz

Students will have a quiz over metamorphic rocks on Wednesday, February 15.  They received a study guide as well as a list to study in class. The study guide was due today.  Here is the list to study:

*Metamorphic rocks are formed from extreme heat and pressure deep underground (deep underground, rocks in the crust/mantle are under extreme heat and pressure but do not melt into magma.  The heat and pressure change them into a different kind of rock).

*Takes thousands or millions of years to form

*foliated metamorphic rocks have bands (stripes) of minerals

*unfoliated metamorphic rocks do not have bands

*Metamorphic rocks can form from any type of rock (igneous, sedimentary, or metamorphic)

*All 3 types of rocks can be found underground so they can turn into metamorphic rocks; shifting of earth (plates) cause continents to move as well as rocks that are under the surface:

-Igneous - intrusive igneous rocks are formed underground

-Sedimentary - all sedimentary rocks are formed under large bodies of water

-Metamorphic - all metamorphic rocks are formed underground
