Wednesday, 17 November 2010
Journal:
Describe the rock on your table. Use as much detail
as possible. What does it look like? Where do you
think it came from? How do you think it was formed?
Plan for the Day:
• Notes
• Rock Observations
• Assignment

8. Rocks - Igneous Rocks
Classifying Igneous Rocks
Igneous rocks are classified according to their origin, texture,
and mineral composition.

11. Rocks - Igneous Rocks
Mineral Mixture
Granite is a mixture of light-
colored minerals, such as
feldspar and quartz, and dark-
colored minerals, including
hornblende and different types
of mica. But granite can vary in
mineral composition. This affects
its color and texture.
Study the circle graph and then
answer the questions.

Mineral Mixture
Reading Graphs:
What mineral is most
abundant in granite?
Feldspar

13. Rocks - Igneous Rocks
Mineral Mixture
Reading Graphs:
About what percentage of
granite is made up of dark
minerals?
10%

14. Rocks - Igneous Rocks
Mineral Mixture
Calculating:
If the amount of quartz increases
to 35 percent and the amount of
dark-colored minerals stays the
same, what percentage of the
granite will be made up of
feldspar?
100% - (35% + 10%) = 55%

15. Rocks - Igneous Rocks
Mineral Mixture
Predicting:
How would the color of the
granite change if it contained
less feldspar and more mica
and hornblende?
The overall color would be
darker.
