DAY 12 | The Rock Cycle

What type of rock forms when molten rock cools and hardens?

• Igneous

• Sedimentary

• Metamorphic

• Mineral

How are sedimentary rocks formed?

• When molten rock cools

• When rocks are changed by heat and pressure

• When sediments are compressed together

• When rocks are broken down by wind and water

What is the rock cycle?

• A type of rock that changes color

• The process of rocks breaking down into sand

• An interconnected system of processes that cause rocks to change over time

• A cycle of rocks moving from one place to another

What processes break rocks down into tiny pieces?

• Compaction and cementation

• Weathering and erosion

• Heating and pressure

• Melting and cooling

What process transforms rocks due to intense heat and pressure?

• Weathering

• Erosion

• Metamorphism

• Compaction

What is the name for the continuous process where rocks change from one type to another over time?

• The water cycle

• The rock cycle

• The mineral cycle

• The erosion cycle

Can an igneous rock like granite eventually become a sedimentary rock like sandstone?

• Yes, but only if it melts first

• No, rocks can only change into metamorphic rocks

• Yes, through weathering, erosion, compaction, and cementation

• Only if it is exposed to extreme heat and pressure
