What are the two types of igneous rocks?
Intrusive and extrusive
What's the difference between the them?
Intrusive forms inside the Earth. Extrusive forms outside the Earth.
What do most rocks have in common?
Most rocks are made of minerals
What are minerals?
inorganic (non-living), natural (not man-made), solid substances

2. Salol Crystals (Part 2, steps 11-18)
Investigation 8
One Rock to Another 2

3. Variables
What are some of the variables that might affect the size of the crystals that form?
Temperature
Rate of cooling
Length of time in hot water
The way the bottle lies as it cools

4. Crystal Size Investigation
Procedure:
1. Each group will get 2 bottles of salol.
2. Place both bottles in hot water to melt.
3. Place one bottle on its side in ice water and the other bottle on its side in room temperature water.
4. Observe and record every 30 seconds.
5. Compare the crystals in the two bottles when all the material has crystallized. 4

What forces are constantly shaping and reshaping Earth’s surface? (Hint: constructive/destructive, use RB p )
Earth processes are going all the time. Destructive processes break down landforms. These include weathering, erosion, and tectonic plates sinking and melting. Constructive processes build up. They include mountain building, deposition (sedimentation), and new crust formation.
When igneous rock forms underground, is it likely to form faster, slower, or at the same rate as igneous rock that forms on Earth's surface?
Slower. There is extreme heat inside Earth, so molten rock that is trapped underground will cool and harden slowly.
