The Rock Cycle and Sedimentary Rocks

What are the two main forces driving the rock cycle?

• Earth's internal heat engine and the hydrological cycle

• Plate tectonics and volcanic activity

• Solar radiation and gravitational pull

• Wind erosion and ocean currents

Which process involves the breakdown of bedrock into smaller particles?

• Weathering

• Erosion

• Deposition

• Cementation

What type of sedimentary rock is formed from fragments of pre-existing rocks?

• Clastic sedimentary rock

• Chemical sedimentary rock

• Metamorphic rock

• Igneous rock

How are chemical sedimentary rocks formed?

• From the precipitation of minerals from water

• By the compaction of sediments

• Through the cooling of magma

• By the erosion of cliffs

What can cause sedimentary rocks to transform into metamorphic rocks?

• Heat and pressure

• Weathering and erosion

• Deposition and cementation

• Cooling and solidification
