1. What is an aquifer?
Answer: B
Aquifers are underground permeable rock layers that store and transmit groundwater.
2. What happens during the process of weathering?
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?
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?
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?
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?
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?
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?
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?
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?
Answer: C
Igneous rocks (like granite and basalt) form when magma inside Earth or lava on the surface cools and crystallizes.
