Essential Question: Why are there different types of rocks?
Name: ___________________Developing Understanding:___/36
Rocky Inquiries--For each of the rock families you and your group need to do the following:
-1st … define the vocab. words in YOUR NB—(write the WORD & the definition)!
-2nd … answer the questions for each part (make sure you ORGANIZE & # these in your NB).
-3rd … key out the samples in your boxes by filling out the tableand have them checked by the master.

Part A) Igneous Family:__/12
--Vocabulary: Felsic, Mafic, Magma, Lava, Vesicular=bubbly (air pockets)
--Igneous Questions:
1) What is the difference between intrusive and extrusive igneous rocks?
2) What is the difference between a light colored & a dark colored igneous rock?
3) What does texture/crystal size tell you about how an igneous rock formed?
4) Explain the 3 ways a rock can melt AND how they would melt rock
Part B) Sedimentary Family:___/12
--Vocabulary: Clastic Sed. Rock, Chemical Sed. Rock, Organic Sed. Rock, Strata/Stratafication, Fossil
--Sedimentary Questions:
1) How do sedimentary rocks differ from igneous rocks?
2) What does the presence of sedimentary structures/appearances indicate regarding the
past environmental history of an area? (think Climate)
3) Sedimentary rock is also classified by the way it forms. How do Clastic, Chemical, and
Organic rocks each form?
Part C) Metamorphic Family:___/12
--Vocabulary: Metamorphism, Foliated, Non-foliated.
--Metamorphic Questions:
1) What are the two types metamorphism that can cause a rock to change?
2) Why do temperature and pressure increase as you/a rock go deeper down into Earth?
3) How are metamorphic rocks related to all other rocks? (think Rock Cycle)
