Obsidian, a shiny naturally made volcanic glass, is formed when lava rapidly cools without much time for crystallization to occur. Early civilizations used obsidian to make arrowheads, knives, spear heads, and other weapons and tools.

Based on the processes of its formation, obsidian is classified as –

A sedimentary rock

B fossilized rock

C metamorphic rock

D igneous rock

Which material would best represent the asthenosphere?

A. A saltine cracker because it shows how the asthenosphere can be broken into different pieces.

B. A balloon because it shows how the asthenosphere is less dense than the other layers and it is hollow.

C. A piece of clay because it shows how the asthenosphere is a dense solid and it has plasticity.

D. A brick because it shows how the asthenosphere is dense and it does not have plasticity.

Which statement lists the layers in the correct order from the center of

Earth to the outermost layer of Earth?

C. Outer Core, Inner Core, Mantle, Crust

D. Outer Core, Inner Core, Crust, Mantle

A rock sitting on the surface of the Earth is pushed down deep into the Earth over time and is exposed to tremendous heat and pressure over time. Although the rock does not melt, it does change into a new type of rock.

How would the new rock be classified?

• Magma

• Metamorphic

• Sedimentary

• Igneous

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

The Earth is made of many layers. Which layer is made up of part crust and part mantle

material?

• Inner core

• Outer core

• Lithosphere

• Asthenosphere

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

A. igneous rock

B. sedimentary rock

C. metamorphic rock

D. fossilized rock
