Lithosphere and Rock Cycle Quiz

What is the lithosphere?

• The layer of the Earth's atmosphere

• The area where rocks behave like plastic

• The process of rock formation

• The movement of tectonic plates

What are tectonic plates?

• Pieces of the Earth's crust that float on the mantle

• Underwater cliffs between beach and ocean

• The process of weathering and erosion

• The movement of rocks in the lithosphere

What causes the movement of tectonic plates?

• Convection currents in the mantle

• Weathering and erosion

• Heat and pressure

• Crystallisation of rocks

What are the three main types of rocks?

• Sedimentary, Metamorphic, Igneous

• Plastic, Crystallised, Weathered

• Intrusive, Extrusive, Compacted

• Fine, Medium, Coarse

How are rocks classified?

• By their grain size

• By their hardness

• By their usual color

• By their formation process

What is the process of weathering?

• Breaking down of rocks into sediment

• Moving sediment away by wind and water

• Melting of rocks into magma

• Crystallisation of rocks below the Earth's surface

What causes physical weathering?

• Chemical reactions

• Acid rain

• Freezing and expanding of water

• Roots of trees splitting rocks

What are sediments?

• Rock particles washed into rivers and deposited on the river bed or in the sea

• Crystallised rocks below the Earth's surface

• Molten rock containing suspended crystals

• Rock particles broken down by chemical reactions

What happens to rocks as we move deeper into the Earth?

• They become softer

• They become harder

• They melt into magma

• They crystallise on or above the Earth's surface

What is the difference between intrusive and extrusive rocks?

• Intrusive rocks crystallise below the Earth's surface, while extrusive rocks crystallise on or above the Earth's surface

• Intrusive rocks are fine-grained, while extrusive rocks are coarse-grained

• Intrusive rocks are soft, while extrusive rocks are hard

• Intrusive rocks are light in color, while extrusive rocks are dark in color
