The Rock Cycle

Front

Antelope Canyon in Arizona is surrounded by sandstone, a sedimentary rock. Which process most likely carved the canyon from the surrounding rock? Options: weathering, pressure increase, melting, subduction.

Back

weathering

Front

What produces igneous rocks?

Back

All of the above (molten material, lava, magma)

Front

A classification system for igneous rock, based on cooling rate, would most likely be based on which of the following?

• the size of the crystals in the rock
• the color of the rock
• the mineral composition of the rock
• the density of the rock

Back

the size of the crystals in the rock

Front

How do metamorphic rocks form?

Back

Heat and Pressure are applied.

Front

What may happen to rock after it is pushed below during subduction?

Back

This exposes rock to high temperatures and pressures that could lead to metamorphism and melting.

Front

Which of the following is a TRUE statement about the rock cycle?

• weathering occurs in igneous rocks but never in sedimentary or metamorphic
• sedimentary rock can revert to metamorphic rock but never to igneous rock
• heat, pressure, cooling, weathering, erosion, and deposition change rock
• the formation of rock within the cycle ends after metamorphic rocks form

Back

heat, pressure, cooling, weathering, erosion, and deposition change rock

Front

Granite is a ________________ rock formed from cooling magma. When granite is weathered and the pressure applied to the deposited particles, sandstone, a ___________ rock is formed.

Back

Igneous , sedimentary

Front

What is mining?

Back

removing rocks from the earth

Front

Which processes from the rock cycle are necessary for fossil fuels to form? Options: melting, high pressures, high temperatures, weathering

Back

high temperatures
