3. 3. Why is the hydrosphere important for Earth's climate regulation? It produces all the Earth's oxygen. b) It absorbs and redistributes heat around the planet. c) It is the main source of volcanic activity. d) It reflects sunlight back into space.

4. 4. What is the main difference between terrestrial biomes and aquatic biomes? a) Terrestrial biomes are found in water, while aquatic biomes are on land. b) Terrestrial biomes are characterized by temperature and precipitation, while aquatic biomes are characterized by salinity and depth. c) Terrestrial biomes have no plant life, while aquatic biomes have abundant plant life. d) Terrestrial biomes consist of only forests, while aquatic biomes consist of deserts.

5. 5. If a freshwater source is contaminated by pollutants, which part of the hydrosphere is directly affected? a) Groundwater b) Ocean water c) Saltwater lakes d) Ice caps

6. 6 . Which of the following scenarios demonstrates the interaction between the hydrosphere and the biosphere? a) A volcanic eruption releasing ash into the atmosphere b) Rainfall creating a habitat for amphibians in a wetland c) A mountain range blocking the path of migratory birds d) Earthquake activity creating new landforms

7. 7. Analyze the role of the hydrosphere in the water cycle. Which of the following processes directly involves the hydrosphere? a) Photosynthesis b) Evaporation from oceans and lakes c) Decomposition of organic matter d) Rock formation

8. 8 . How does the concept of a population differ from that of a community in the biosphere? a) A population includes multiple species, while a community consists of individuals of a single species. b) A population consists of individuals of a single species, while a community includes multiple species interacting in a specific area. c) A population is larger than a community. d) A community is part of a population.

9. 9. Propose a scenario where changes in the hydrosphere could impact the biosphere. Which scenario fits this proposal? a ) A decrease in ocean salinity leading to the extinction of saltwater fish species b) An increase in freshwater availability leading to the expansion of desert ecosystems c) A decrease in global temperatures leading to increased evaporation from the oceans d) A reduction in greenhouse gases leading to more abundant plant life in aquatic biomes

10. 10. Evaluate the significance of the three domains of life (Archaea, Bacteria, and Eukarya) in the biosphere. Which domain plays the most critical role in maintaining ecological balance, and why? a) Archaea, because they are found in extreme environments and contribute to the recycling of nutrients. b) Bacteria, because they are involved in processes such as decomposition and nitrogen fixation. c) Eukarya, because they include plants, animals, and fungi, which are essential for food chains. d) All three domains are equally important, as they interact to support the biosphere.
