1.4.2 The Rock Cycle

• Igneous rocks form when molten rock cools and solidifies
• Order the key processes in the rock cycle

  1️⃣ Melting

  2️⃣ Cooling

  3️⃣ Weathering

  4️⃣ Erosion

  5️⃣ Compaction and Cementation

  6️⃣ Heat and Pressure
• Metamorphic rocks are formed by heat and pressure acting on existing rocks.


  True
• Granite is an igneous rock with coarse-grained texture.
• What is the first step in the formation of sedimentary rocks?

  Weathering
• What type of sedimentary rock forms from mineral precipitates?

  Chemical
• Heat and pressure can transform rocks into metamorphic rocks.


  True
• Metamorphic rocks form when existing rocks are changed by heat and pressure.

  True
• The cooling rate of magma determines the texture of igneous rocks.


  True
• Arrange the formation processes of sedimentary rocks in the correct order:

  1️⃣ Weathering

  2️⃣ Erosion

  3️⃣ Deposition

  4️⃣ Compaction

  5️⃣ Cementation
• Plate tectonics drives many of the key processes in the rock cycle.


  True
• Plate tectonics drives processes in the rock cycle by causing the melting of solid rock into magma.


  True
• The metamorphism of existing rocks occurs due to heat and pressure within the Earth's crust.
• Match the plate tectonic process with its impact on the rock cycle:

  Plate Convergence ↔️ Melting, Metamorphism

  Plate Divergence ↔️ Melting, Cooling, Igneous Rock Formation

  Plate Movement ↔️ Weathering, Erosion, Sedimentary Rock Formation

  7️⃣ Heat and Pressure
• Igneous rocks are classified by their mineral composition and texture.
• Rocks break down into smaller pieces called sediments
• Which key processes are involved in the formation of clastic sedimentary rocks?

  Weathering, Erosion, Deposition, Compaction, Cementation
• Metamorphic rocks are formed from parent rocks by intense heat and pressure
• The type of metamorphic rock formed depends on the composition of the parent rock and the intensity of heat and pressure.


  True
• What is the rock cycle?

  Transforms rocks continuously
• What process changes solid rock into magma?

  Melting
• Weathering, erosion, and compaction are key processes in the formation of sedimentary rocks.
• Order the key processes in the formation of igneous rocks

  1️⃣ Melting

  2️⃣ Cooling
• Basalt is an igneous rock with fine-grained texture.
• Sandstone is an example of a clastic sedimentary rock.
• Erosion carries away weathered material
• The rock cycle is a continuous process that transforms rocks from one type to another
• What is magma?

  Molten rock
• Sedimentary rocks form from sediments that have been broken down, transported, and consolidated
• What are the key processes involved in metamorphism?

  Heat and pressure
• The melting of solid rock into magma leads to the formation of igneous rocks.
• Order the processes involved in the formation of sedimentary rocks

  1️⃣ Weathering

  2️⃣ Erosion

  3️⃣ Deposition

  4️⃣ Compaction

  5️⃣ Cementation
• Weathering and erosion of rocks create sediments, which eventually form sedimentary rocks.


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

  Igneous, Sedimentary, Metamorphic
• What is magma, and what does it form when it cools?

  Molten rock, igneous rocks
• What are the five steps in the formation of sedimentary rocks?

  Weathering, Erosion, Deposition, Compaction, Cementation
• There are two main types of sedimentary rocks: clastic and chemical
• Sandstone and shale are examples of clastic sedimentary rocks.


  True
• What are the two key processes involved in the formation of metamorphic rocks?
