Question and Answers
1. What are the four spheres of the earth?
Answer: The four spheres of the earth are lithosphere (land), hydrosphere (water), atmosphere (air), and biosphere (living world).
2. Name the seven continents.
Answer: The seven continents are Asia, Europe, Africa, North America, South America, Antarctica, and Australia.
3. What is the difference between ocean water and river water?
Answer: Ocean water is salty whilst river water is fresh and not salty.
4. What is groundwater?
Answer: Groundwater is the water stored in the underground layers of rock. We reach it through dug wells and bore wells.
5. What are the five oceans?
Answer: The five oceans are Atlantic, Pacific, Arctic, Southern Ocean, and Indian Ocean.
6. What is a glacier?
Answer: A glacier is a huge mass of ice that forms when layers of snow pile up in low-lying areas and slip down a slope at very slow speed.
7. What is the water cycle?
Answer: The water cycle is the continuous process of evaporation, condensation, and rainfall that goes on in nature.
8. What are tributaries?
Answer: Tributaries are rivers which join to make a bigger river.
9. What is the troposphere?
Answer: The troposphere is the layer of atmosphere that extends from the earth’s surface to a height of about 13 km.
10. Why is the ozone layer important?
Answer: The ozone layer is important because it absorbs harmful ultraviolet rays coming from the sun and protects living things from them.
11. What is the biosphere?
Answer: The biosphere is the living world that includes all plants, animals, and micro-organisms found on land, in water, and in the air.
12. What are landforms?
Answer: Landforms are different shapes given to the land due to its unevenness in different places, such as plains, hills, mountains, valleys, etc.
13. How are clouds formed?
Answer: Clouds are formed when water vapour rises high in the atmosphere, cools down, and condenses into very fine droplets of water that float in the air.
14. What is condensation?
Answer: Condensation is the process of vapour turning into water on cooling.
15. Why do mountaineers carry oxygen cylinders?
Answer: Mountaineers carry oxygen cylinders because the air becomes rarer at high altitudes, making it difficult to breathe normally.
