Understanding the Rock Cycle Concepts

What are the three main types of rocks discussed in the rock cycle?

• Granite, Basalt, Sandstone

• Igneous, Sedimentary, Metamorphic

• Hard, Soft, Medium

• Volcanic, Oceanic, Continental

What does the rock cycle describe?

• The movement of rocks across continents.

• The continuous process where rocks are formed, changed, and destroyed.

• The study of rock properties and mineralogy.

• The formation of mountains and valleys.

How are igneous rocks primarily formed?

• From the compaction of sediments.

• From the cooling and solidification of molten magma or lava.

• From existing rocks undergoing heat and pressure.

• From the erosion of mountains.

What process breaks down igneous rocks into smaller pieces that can eventually form sedimentary rocks?

• Melting

• Subduction

• Weathering and erosion

• Intense heat and pressure

What conditions are necessary to transform existing rocks into metamorphic rocks?

• Exposure to wind and rain.

• Cooling of magma.

• High heat and pressure.

• Deposition in sedimentary basins.

Which process involves oceanic crust sinking into the mantle, where it can melt and eventually lead to the formation of new igneous rock?

• Lithification

• Weathering

• Subduction

• Compaction

What is the process called when magma turns into igneous rock?

• Melting

• Cooling

• Compaction

• Weathering

How do sediments become sedimentary rock?

• Through melting and cooling.

• Through intense heat and pressure.

• Through compaction and cementation.

• Through volcanic eruption.

What process must metamorphic rock undergo to become magma?

• Weathering

• Compaction

• Melting

• Lithification

What is the primary role of weathering in the rock cycle?

• To melt rocks into magma.

• To transform rocks into metamorphic rocks.

• To break down rocks into smaller pieces (sediments).

• To push rocks up to the Earth's surface.
