1. Welcome to Science 11/2
Get your HW out. You will be working with a partner to answer three questions that you will find in a book about rocks. You have 10 minutes to complete this.

2. Turn in HW The Global Village
If the world’s pop. was 100 people with all of the existing human ratios remaining the same, the village would include:
60 Asians, 12 Europeans, 9 Latin Americans, N. Americans, 1 Oceanian, 13 Africans
50 female/50 male, 80 nonwhite/20 white
20 people would earn 89% of the wealth
25 would live in substandard housing
17 would be unable to read
13 would suffer from malnutrition
1 would die within the year
2 would give birth within the year
2 would have a college education
4 would have a computer

3. Welcome to Science 11/2
Observe the pictures below. On your paper, list as many similarities as you can about the pictures.

4. I. Classifying Rocks
Observe the rock on your desk. On your paper, list as many descriptions of the rock as you can.
When classifying rocks, what 3 characteristics of rocks do geologists study?
1. Mineral Composition (what the rock is made of)
2. Color
3. Texture

5. II. 90% of Earth’s crust is made of Igneous Rocks. Why?
Igneous- comes from the Latin word for “fire”
Origin- born from the cooling and hardening of magma & lava

6. III. Composition & Texture
The type of igneous rock that forms depends on what it is made of and how fast it cools.
Slow cooling magma/lava = coarse,rough text.
Fast cooling magma/lava = smoother, text.
Slowest nd Slowest Fastest

7. IV. Igneous Rock Formations
Intrusive Rock- magma that has cooled beneath Earth’s surface.
Volcanic necks, plutons, batholiths
volcanic neck

8. V. Igneous Rock Formations
Extrusive Rock- forms from the cooling of lava on Earth’s surface
Why are these rocks important?
This is a major process responsible for building new crust.

9. Assignment: Acrostic Poem
Your assignment for tonight is to create an acrostic poem for the word igneous. Here is an example.
