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

• Sedimentary

• Metamorphic

• Igneous

• Fossil

Answer explanation

Igneous rocks are formed from the cooling and solidification of magma or lava. Sedimentary rocks form from sediment, and metamorphic rocks arise from existing rocks under heat and pressure. Fossil is not a rock type.

Which layer of the Earth is the outermost layer?

• Inner core

• Outer core

• Mantle

• Crust

Answer explanation

The crust is the outermost layer of the Earth, lying above the mantle. It is solid and forms the continents and ocean floors, while the inner and outer cores and mantle are beneath it.

Which system of Earth includes all living organisms?

• Hydrosphere

• Atmosphere

• Biosphere

• Geosphere

Answer explanation

The biosphere is the system of Earth that encompasses all living organisms, including plants, animals, and microorganisms. It interacts with the hydrosphere, atmosphere, and geosphere, but specifically refers to life itself.

Why is resource management important in reducing air and water pollution?

• It increases pollution

• It helps in sustainable development

• It depletes resources

• It has no effect on pollution

Answer explanation

Resource management is crucial for sustainable development as it ensures efficient use of resources, reducing waste and pollution. By managing resources wisely, we can minimize air and water pollution, promoting a healthier environment.

What process transforms sedimentary rock into metamorphic rock?

• Melting

• Cooling

• Heat and pressure

• Erosion

Answer explanation

Sedimentary rock transforms into metamorphic rock primarily through the application of heat and pressure, which alters its mineral composition and structure without melting it.

Which layer of Earth is composed of liquid iron and nickel?

• Inner core

• Outer core

• Mantle

• Crust

Answer explanation

The outer core is the layer of Earth that is composed of liquid iron and nickel, while the inner core is solid, and the mantle and crust are primarily made of silicate rocks.

Which Earth system includes oceans, rivers, and lakes?

• Biosphere

• Atmosphere

• Hydrosphere

• Geosphere

Answer explanation

The hydrosphere encompasses all water bodies on Earth, including oceans, rivers, and lakes. This makes it the correct choice, as the biosphere refers to living organisms, the atmosphere to air, and the geosphere to land.
