CBA #3 Review

When magma is forced between rocks in the Earth’s crust and it cools and crystalizes deep underground, Granite is formed. Granite contains large, visible crystals because the magma cooled slowly. Granite is often used in kitchen countertops, monuments, and buildings. The Texas State Capitol was constructed from red granite from Granite Mountain near Marble Falls, Texas.

Granite is classified as ―

• fossilized rock

• metamorphic rock

• igneous rock

• sedimentary rock

What process is occurring at location W?

• compaction and cementation

• weathering and erosion

• heating and melting

• cooling and hardening

Which of the following processes is most likely to occur at location Z?

• Solid rock is weathered

• Solid rock melts

• Rocks become uplifted

• Magma cools and hardens

A student wanted to make a model of the Earth. The student decided to cut a giant Styrofoam ball in half and paint the layers on it to show their thickness.

Which model below best represents the layers of the Earth?

• 
• 
• 
• 

Long periods of extreme heat and pressure result in the formation of —

• igneous rock

• sedimentary rock

• metamorphic rock

• fossilized rock

A student made peanut butter bars by pressing a layer of graham cracker crumbs into a baking pan. Next, the student added a layer of a peanut butter mixture and then added a layer of crushed peanuts. Lastly, the student added a layer of chocolate frosting.

The process of making peanut butter bars is most like the formation of what type of rock?

• Igneous

• Metamorphic

• Sedimentary

• Magma

Which layer in the image above represents the layer of the Earth composed of liquid metal?

• 1

• 2

• 3

• 4

Which rock sample is most likely a metamorphic rock?

• Sample A

• Sample B

• Sample C

• Sample D

Some students use an apple to represent the Earth. What is the best reason to use an apple for this comparison?

• The skin of an apple is very thin, and the crust of the Earth is very thin.

• The flesh of an apple is made of the same material all the way through, and the interior of the Earth is the same all the way through.

• The seeds of the apple are very light in comparison to the rest of the apple, and the core of the Earth is also made of very light matter.

• The stem of the apple comes from the core and the North Pole comes from the Earth’s core.

The most dense layer of the Earth is:

• Crust

• Mantle

• Core
