S2. Ans.(d)
Sol. India is the seventh largest country on the basis of land area of 32,87,263

S3. Ans.(a)
Sol. India is the fifth largest exporter of iron ore in the world. We export about 50 to 60 per cent of our total iron ore production to countries like Japan, Korea, European countries and lately to Gulf countries. Japan is the biggest buyer of Indian iron ore accounting for about three-fourths of our total exports.

S4. Ans.(a)
Sol. During the day, the land surface heats up faster than the water surface. The air above the land is warmer than the air above the ocean. As the warm air over the land is rising, the cooler air over the ocean is flowing over the land surface to replace the rising warm air. This is the sea breeze.

S5. Ans.(c)
Sol. The Ring of Fire is a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur. It is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements.

Sol. Taiga also known as boreal forest or snow forest is a biome characterized by coniferous forests consisting mostly of pines, spruces and larches.

Sol. One of the most important natural causes of air pollution is volcanic eruption. Volcanic eruptions can generate so much polluting gases and ash into the air that the sun’s rays could be blocked, and land temperature in the affected area lowered. The ash can cause respiratory problems for young children, the elderly or those already with respiratory ailments.

S9. Ans.(a)
