Earth Science and Geoscience Quiz

Relationship between Earth Science and Planetary Science

• Earth science is a subset of planetary science, as it focuses on the Earth, while planetary science explores other planets and celestial bodies as well.

Earth's Spheres

• The four spheres of Earth are: geosphere (land), hydrosphere (water), atmosphere (air), and biosphere (living organisms).
• The correct answer is: crust, which is a part of the geosphere, not a separate sphere.

Energy and Mineral Resources

• Some Earth scientists study the formation and distribution of energy and mineral resources, such as fossil fuels, metals, and other valuable minerals.

Contribution to Disaster Prevention

• Earth scientists contribute to protecting people from dangerous events like earthquakes, volcanic eruptions, landslides, and hurricanes by monitoring and predicting these events.

Scope of Earth Sciences

• Earth sciences can include the study of the Earth's internal and external processes, such as plate tectonics, earthquakes, volcanoes, and the Earth's surface and atmospheric systems.

Magmatism and Volcanism

• Magmatism is the process of magma generation, ascent, and emplacement.
• Volcanism is the process of magma eruption onto the Earth's surface.

Mountain Formation

• One of the main processes responsible for mountain formation is plate tectonics, which involves the movement of the Earth's lithosphere and the resulting folding and faulting of rocks.

Andesitic Magmatism

• Andesitic magmatism is typically found at subduction zones, where an oceanic plate is being subducted beneath a continental plate.

Magma Formation

• Magma forms on Earth through the partial melting of the Earth's mantle, resulting in a mixture of molten rock, gases, and minerals.
