Two or more different air masses that approach one another and can lead to a change in the weather.
A front
300
By which two processes is a metamorphic rock formed?
Pressure and heat
300
Which rocks can be foliated and non-foliated? What is the difference?
Metamorphic; foliated rocks have bands of flat minerals that look like stripes

How do igneous rocks form?
Magma is produced by melting metamorphic rocks. When the magma cools, it becomes an igneous rock
400

Describe the formation of a cloud
Warm, moist air rises until it cools down enough to condense. There are 3 different forces that can cause a warm air mass to be pushed upward.
1) A front
2) Air pushed up over a mountain
3) Evaporation from the sun's heat

What are the 6 different ways of categorizing igneous rocks and what does each of the categories mean?
Felsic - light color
Mafic - dark color
Coarse-grained - took longer to cool
Fine-grained - cooled quickly
Intrusive - formed from magma below the earth's surface
Extrusive - formed by erupted magma
