How does the thicknesses of the lithosphere compare to the thickness of the crust?

• The lithosphere is thinner than the crust

• The lithosphere is exactly the same thickness as the crust.

• The lithosphere is thicker than the crust.

• The lithosphere is thicker than the oceanic crust, but thinner than the continental crust

Which layer of the Earth is made of liquid metal (nickel and iron)?

• crust

• mantle

• outer core

• inner core

Marble, a common metamorphic rock is formed from the sedimentary rock limestone. Marble is commonly used in architecture and sculpture. Many famous buildings are made of marble, including the Washington Monument, the Taj Mahal, the Lincoln Memorial, and the Supreme Court Building.

What processes occur in the formation of marble?

• Limestone is weathered, eroded, cemented, and compacted

• Limestone is buried deep in the Earth and undergoes long periods of extreme heat and pressure.

• Limestone is melted, cooled, and hardened

• Limestone is washed away by running water, fossilized, and buried deep underground in layers.

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

Limestone is a common sedimentary rock found in Texas. How did the limestone most likely form?

• Lava from volcanic eruptions cooled and hardened

• Oceanic deposits were layered and cemented together

• Extreme heat and pressure inside the Earth melted the sediment

• Partial melting of rocks into magma that fossilized

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

• igneous rock

• sedimentary rock

• metamorphic rock

• fossilized rock

Which type of rock forms when an existing rock changes under extreme pressure and intense heat?

• igneous

• sedimentary

• metamorphic

Which type of rock forms through weathering, erosion and deposition?

• igneous

• sedimentary

• metamorphic
