Rocks and the Rock Cycle

What is the rock cycle?

• The rock cycle is a type of exercise involving lifting heavy rocks

• The rock cycle is a continuous process of rock formation, transformation, and reformation.

• The rock cycle is a method of cooking using hot rocks

• The rock cycle is a popular rock band from the 1980s

Name the three types of rocks involved in the rock cycle.

• granite, limestone, and marble

• magma, shale, and slate

• igneous, sedimentary, and metamorphic

• volcanic, sedimentary, and crystalline

Explain how igneous rocks are formed in the rock cycle.

• Magma cools and solidifies to form igneous rocks.

• Igneous rocks are formed by the compression of organic materials.

• Igneous rocks are formed by the cooling of water.

• Igneous rocks are formed by erosion and sedimentation.

Describe the process of sedimentary rocks turning into metamorphic rocks in the rock cycle.

• Erosion by wind and water

• Volcanic eruption

• Freezing and thawing

• Recrystallization due to heat and pressure

How are metamorphic rocks formed in the rock cycle?

• Metamorphic rocks are formed from sedimentary rocks through erosion

• Metamorphic rocks are formed from volcanic eruptions

• Metamorphic rocks are formed from organic matter decomposition

• Metamorphic rocks are formed from existing rocks that are subjected to high heat, high pressure, or both.

What are the forces that drive the rock cycle?

• Gravity, erosion, and deposition

• Chemical reactions, sedimentation, and compaction

• Volcanic activity, earthquakes, and landslides

• Heat, pressure, and weathering

What are the different types of igneous rocks and how are they formed?

• There are five main types of igneous rocks: marble, limestone, sandstone, shale, and slate.

• There are four main types of igneous rocks: granite, basalt, obsidian, and pumice.

• There are three main types of igneous rocks: sedimentary, metamorphic, and volcanic.

• There are two main types of igneous rocks: intrusive and extrusive.

Describe the process of weathering and erosion in the rock cycle.

• Weathering creates new rocks from scratch

• Weathering breaks down rocks and erosion transports and deposits the pieces in new locations.

• Erosion causes rocks to become harder and more resistant

• Weathering and erosion have no impact on the rock cycle

Explain the role of magma and lava in the formation of igneous rocks.

• Igneous rocks are formed from sedimentary rocks, not magma and lava

• Magma and lava are the molten materials that cool and solidify to form igneous rocks.

• Magma and lava are not involved in the formation of igneous rocks

• Magma and lava are the result of igneous rocks breaking down

How do sedimentary rocks form in the rock cycle?

• By the process of evaporation and crystallization

• Through volcanic activity and cooling of magma

• Through the movement of tectonic plates and folding of layers

• Through the process of weathering, erosion, deposition, compaction, and cementation.
