Which of the following is a natural resource from the biosphere?

• Wood (timber)

• Water

• Oxygen

What process forms sedimentary rocks?

• When magma or lava cools causing crystalisation

• Weathering and erosion of pre-existing rocks, which are then deposited, compacted, and cemented together

• Exposure to extreme heat and pressure

Which is an example of an igneous rock?

• Sandstone

• Slate

• Borrowdale volcanics

• Coal

Which sphere are rocks found in?

• Lithosphere

• Atmosphere

• Hydrosphere

• Biosphere

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

• Intrusive rocks form when magma cools slowly underground whilst extrusive rocks form when lava cools quickly on the surface

• Intrusive rocks form tiny crystals, while extrusive rocks form large crystals

• Intrusive rocks are softer, while extrusive rocks are harder

• Intrusive rocks are made from sediments, while extrusive rocks are made from magma or lava cooling

Which describes the formation of metamorphic rocks

• Formed when magma or lava cools

• Made of sediments which are deposited in layers

• Existing rocks that have been changed by extreme heat or pressure

Which is mechanical weathering?

• The process of rocks dissolving due to slightly acidic rainwater

• The breakdown of rock by plant roots or animals

• The breakdown of rock through the freeze-thaw process
