Exploring Rocks and Their Cycles

Which process is responsible for breaking down rocks into smaller pieces on the Earth's surface?

• Melting

• Weathering

• Compaction

• Crystallisation

What is the main difference between intrusive and extrusive igneous rocks?

• Intrusive rocks form on the surface, extrusive rocks form underground

• Intrusive rocks have larger crystals, extrusive rocks have smaller crystals

• Intrusive rocks are always darker in colour

• Extrusive rocks contain fossils

Which of the following is NOT a process in the rock cycle?

• Erosion

• Freezing

• Melting

• Compaction

Granite is an example of which type of rock?

• Sedimentary

• Metamorphic

• Igneous

• Organic

What is magma?

• Solidified lava on the Earth's surface

• Molten rock beneath the Earth's surface

• Weathered rock fragments

• Compacted sediment

Which process turns sediment into sedimentary rock?

• Melting and cooling

• Compaction and cementation

• Crystallisation

• Erosion

Which of the following is a characteristic of igneous rocks?

• They often contain fossils

• They are formed from cooled magma or lava

• They are always layered

• They are formed by evaporation

What is the process called when rocks are broken down and carried away by wind, water, or ice?

• Erosion

• Deposition

• Melting

• Cementation

What happens to rocks during metamorphism?

• They melt completely

• They are broken into smaller pieces

• They change due to heat and pressure

• They dissolve in water

Which process in the rock cycle involves the cooling and solidification of magma or lava?

• Weathering

• Crystallisation

• Erosion

• Compaction
