A student made lemon drop candy by melting sugar, water, and lemon flavoring in a sauce pan until the mixture was at a very high temperature. Next, the student poured the clear yellow mixture onto a baking sheet until it was cool. The process of making lemon drop candy is most like the formation of what type of rock?

• Igneous

• Metamorphic

• Sedimentary

• Conglomerate

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

The diagram below shows some stages in the rock cycle. The rock cycle shows how the three types of rocks can change from one type to another. What process is occurring at location W?

• Pressure and cementation

• Weathering and erosion

• Heating and melting

• Cooling and hardening

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?

• Igneous

• Magma

• Metamorphic

• Sedimentary

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 —

• sedimentary rock

• fossilized rock

• metamorphic rock

• igneous rock

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

Which process best describes the formation of a sedimentary rock?

• Solid rock is weathered, deposited, compacted, and cemented

• Rock is exposed to extreme heat and pressure deep in the Earth

• Lava erupts from a volcano and flows down a mountain

• Magma cools and solidifies beneath the Earth’s surface

The rock cycle is a continual process by which rocks can be changed into different types of rock. What type of rock experiences compaction and cementation?

• Metamorphic and igneous rock experience compaction and cementation.

• Metamorphic rock experiences compaction and cementation.

• Igneous rock experiences compaction and cementation.

• Sedimentary rock experiences compaction and cementation.

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
