Describe how igneous rocks form.
Rocks are melted down into molten rock and then magma/lava cools to form an Igneous rock.
100

What are sedimentary rocks made from?

sediment

100
How are metamorphic rocks formed.
When rocks are put under extreme heat and pressure.
100
The series of processes that slowly changes rocks from one kind to another is known as what?
Rock Cycle

True or False? There are over 100 different rock forming minerals.
False - BONUS: how many rock forming minerals are there?
200
What type of igneous rock forms from lava/surface?
extrusive igneous rocks
200

What is weathering?

Breaking down of rocks

200
What does it mean for a metamorphic rock to be foliated?
grains are in layers; pattern
200
What kind of rock comes from magma/lava?
Igneous Rock
200
What is the look and feel of a rock?
Texture
300
What type of igneous rocks forms from magma/inside the surface?
intrusive igneous rocks
300
How do sedimentary rocks form?
Erosion, Deposition, Compaction, Cementation
300
What kind of metamorphic rock has grains that are not layered and more random?
non-foliated
300
What kind of rock comes from sediment?
Sedimentary Rock
300
Small broken pieces from rocks or living things are called what?
Sediment
400
What is the most common intrusive and extrusive rocks?
Intrusive - granite

Extrusive - basalt

400

Erosion means to transport rocks. How are rocks transported?

wind, water, gravity

400

What is the heat sources for metamorphic rocks.

magma, pressure, friction, radioactive decay.

400

What kind of rocks become metamorphic rocks?

Igneous, Sedimentary, and Metamorphic (All Rocks)

400
The texture of a rock depends on the size and shape of _____________.
grains
500
What is pumice igneous rock used for?
used for cleaning and polishing 
500
What does each step in sedimentary rock mean? (Erosion; Deposition; Compaction Cementation)
Erosion - movement of particles; Deposition - drop off of particles; Compaction - pressing of particles; Cementation - glueing of particles.
500
What is slate used for?
flooring, roofing, walkways, chalkboards.
500
Describe how granite forms and how it could become sandstone?
Lava cools to become granite. Granite gets broken down into sediment/sand (erosion). The sediments/sand get layered and pressed.
