Full Question List & Answer Key

Prefer reading to quizzing? All 10 questions are listed below with the answer and explanation under each one.

1. What is an aquifer?

  1. A deep ocean trench formed by subduction
  2. An underground layer of permeable rock or sediment that holds water
  3. A volcanic crater filled with rainwater
  4. A type of metamorphic mineral deposit
Show answer

Answer: B

Aquifers are underground permeable rock layers that store and transmit groundwater.

2. What happens during the process of weathering?

  1. Rocks are transported by river currents to the ocean
  2. Rocks are broken down into smaller fragments by physical, chemical, or biological agents
  3. Rock fragments settle and compress at the bottom of lakes
  4. Liquid lava cools on Earth's surface
Show answer

Answer: B

Weathering is the in-situ breakdown of rocks into smaller particles by rain, temperature changes, or organisms.

3. Which scientific field involves studying fossils to understand ancient life forms and Earth's history?

  1. Seismology
  2. Paleontology
  3. Meteorology
  4. Volcanology
Show answer

Answer: B

Paleontology is the study of prehistoric life and fossils preserved in geological strata.

4. In which layer of the Earth's atmosphere does weather phenomena such as rain, wind, and clouds occur?

  1. Stratosphere
  2. Troposphere
  3. Mesosphere
  4. Thermosphere
Show answer

Answer: B

The Troposphere is the lowest atmospheric layer containing most water vapor and weather activity.

5. What drives the movement of tectonic plates in Earth's crust according to endogenic theory?

  1. Solar radiation on the crust
  2. Convection currents in the mantle
  3. Gravitational pull of the moon
  4. Oceanic surface tides
Show answer

Answer: B

Thermal convection currents in the semi-fluid asthenosphere/mantle drag tectonic plates along the surface.

6. Which of the following geohazard phenomena is classified as an Endogenic hazard?

  1. Landslide
  2. Flash flood
  3. Earthquake
  4. Sinkhole
Show answer

Answer: C

Earthquakes are caused by stress release along geological faults due to internal plate movements (Endogenic).

7. Why are fossils predominantly found in Sedimentary rocks rather than Igneous rocks?

  1. Sedimentary rocks form under high heat that preserves bones
  2. Igneous rocks form from high-temperature molten rock that melts organic remains
  3. Sedimentary rocks only form deep inside Earth's core
  4. Igneous rocks are too soft to hold fossils
Show answer

Answer: B

Extremely high temperatures of liquid magma during Igneous rock formation destroy organic remains, whereas Sedimentary rocks accumulate gently over time.

8. Which non-metallic economic mineral is commonly used in manufacturing cement and concrete?

  1. Tin
  2. Iron ore
  3. Limestone
  4. Gold
Show answer

Answer: C

Limestone (calcium carbonate) is a major sedimentary mineral used extensively in cement production.

9. Which geological process involves the movement and deposition of eroded rock materials by wind, water, or ice?

  1. Transport and Deposition
  2. Metamorphism
  3. Magma Intrusions
  4. Radioactive Decay
Show answer

Answer: A

Eroded materials are carried (transported) by agents like rivers and wind before settling (deposition) elsewhere.

10. Which rock type is formed from the cooling and solidification of molten magma or lava?

  1. Sedimentary Rock
  2. Metamorphic Rock
  3. Igneous Rock
  4. Fossiliferous Rock
Show answer

Answer: C

Igneous rocks (like granite and basalt) form when magma inside Earth or lava on the surface cools and crystallizes.
