Pulverized limestone is often used in this sidewalk material
Cement (or concrete)

This is how metamorphic rocks are created.
What is extreme heat and pressure

What is igneous rock
200
This type of rock is formed from lava ON the earth's surface.

200
These are the building blocks of rocks

These types of rocks can become metamorphic rocks
What is igneous, sedimentary and other metamorphic rocks
200
Igneous rock transforms to sediment by processes called ___________ & ____________
What is weathering and erosion
200
When hydrothermal fluids change a rock, this type of metamorphism occurs
What is chemical metamorphism?
200
The individual rock particles, crystals, and sometimes fossils that combine to give a rock its texture
What are Grains
300
The type of rock that includes conglomerate and breccia
Sedimentary
300
Name the type of rock that is often used for statues and important buildings because it is very weather resistant. Basalt, like this pictured, is an example.
Igneous
300
The type of rock where fossils are most likely to be found
Sedimentary rock
300
Which is a common example of a nonfoliated metamorphic rock? marble, slate, shale, or schist
Marble
300
The process where layers of sediment become pressed together over time
What is compaction
300
The type of rock where fossils are usually found
what is sedimentary
300
Geologists believe that igneous rock grain size has less to do with how FAST the magma cooled than WHAT?
What is WHERE the cooling happened (like inside or outside of a volcano)
400
What should be replacing the question mark?
What is deposition or sedimentation?
400
This type of igneous rock is black and often called volcanic glass 
What is obsidian
400
This is a common type of intrusive igneous rock is sometimes used to make kitchen counters
What is Granite
400
The texture of a metamorphic rock arranged in parallel layers (bands) is called
What is foliated
400
Changes in a rock that is in contact with magma due to the magma's extreme heat
Contact Metamorphism
400
If rocks cool slowly describe the size of the crystal it will produce
What is large?
400
Compared to the sharp-cornered Breccia, this sedimentary rock is made from rounded pieces of gravel and stones
What conglomerate?
500
This type of rock is closely tied to erosion
What is sedimentary rock
500
This example of sedimentary rock is very useful as a construction material
What is limestone
500
Old-earth geologists believe it took this long for layers of sedimentary rocks to form
what is millions of years
500
Would high-quality marble rock most likely be used for a home foundation or veneer stone on government buildings?
Veneer stone
500
After materials are eroded and deposited, they are "glued" together by this process that makes sedimentary rocks
What is cementation?
500
If granite undergoes high heat and pressure within the Earth, what type of rock (also beginning with "g") will be formed.
Gneiss (a metamorphic rock)
500
This is the settling out of materials from solution to form inorganic nonclastic rocks
What is precipitation
