Exploring Earth's Structure Quiz

Which layer of the Earth is primarily composed of solid iron and nickel?

• Crust

• Mantle

• Outer Core

• Inner Core

Explain how the movement of tectonic plates can lead to the formation of mountains.

• Tectonic plates move apart, creating space for mountains to form.

• Tectonic plates slide past each other, causing mountains to rise.

• Tectonic plates collide, forcing the land upwards to form mountains.

• Tectonic plates sink, allowing mountains to emerge.

Identify the layer of the Earth where convection currents occur, which drive the movement of tectonic plates.

• Crust

• Mantle

• Outer Core

• Inner Core

Evaluate the impact of volcanic eruptions on the Earth's atmosphere and climate.

• Volcanic eruptions have no impact on the atmosphere.

• Volcanic eruptions release gases that can cool the Earth's climate.

• Volcanic eruptions only affect the local area and not the global climate.

• Volcanic eruptions always lead to a warming of the Earth's climate.

What is the primary composition of the Earth's crust?

• Iron and nickel

• Silicate minerals

• Liquid magma

• Solid metal

Discuss the role of the Earth's magnetic field and how it is generated.

• The magnetic field is generated by the rotation of the Earth alone.

• The magnetic field is generated by the movement of molten iron in the outer core.

• The magnetic field is generated by the solid inner core.

• The magnetic field is generated by the Earth's atmosphere.

Which of the following best describes the lithosphere?

• The liquid layer beneath the Earth's crust

• The rigid outer layer of the Earth, including the crust and upper mantle

• The innermost layer of the Earth

• The layer where tectonic plates are found

Analyse how the distribution of earthquakes and volcanoes can provide evidence for the theory of plate tectonics.

• Earthquakes and volcanoes are randomly distributed across the Earth.

• Earthquakes and volcanoes are concentrated along plate boundaries, supporting the theory of plate tectonics.

• Earthquakes occur only in the ocean, while volcanoes occur only on land.

• There is no relationship between earthquakes, volcanoes, and plate tectonics.
