What is the name of the Earth's outermost layer?

• Inner core

• Outer core

• Mantle

• Crust

What type of rock is formed from the cooling and solidification of magma or lava?

• Sedimentary

• Metamorphic

• Igneous

• Fossil

Describe the process by which sedimentary rocks are formed.

• By cooling and solidification of magma

• By heat and pressure transforming existing rock

• By the accumulation and compaction of sediments

• By the fusion of rocks

Explain how the mantle differs from the crust in terms of composition and physical state.

• The mantle is solid and made of iron, while the crust is liquid and made of silicates.

• The mantle is liquid and made of silicates, while the crust is solid and made of iron.

• The mantle is semi-solid and made of silicates, while the crust is solid and made of lighter materials.

• The mantle is solid and made of lighter materials, while the crust is semi-solid and made of silicates.

What process can transform an igneous rock into a metamorphic rock?

• Melting and cooling

• Weathering and erosion

• Heat and pressure

• Compaction and cementation
