The Seasons

Correct answer: A. Because monsoon rainfall is available at this time

Kharif crops need monsoon rain for sowing and growth. Exam tip: connect kharif with the rainy season.

Correct answer: A. Eastern coast

Bay of Bengal cyclones during retreating monsoon can affect the eastern coast. Exam tip: remember eastern coast and cyclones.

Correct answer: A. Because both temperature and humidity can be high

Humidity and heat together create sultriness during retreating monsoon. Exam tip: connect October heat with retreating monsoon.

Correct answer: A. Local low pressure can form

Strong heating can create local low pressure and strong winds. Exam tip: understand the relation between heat and pressure.

Correct answer: A. Because they occur before the South-West Monsoon

The direct answer is option A: they occur before the South-West Monsoon. Mango showers are local pre-monsoon rain, especially associated with parts of southern India, including Kerala and Karnataka. They occur toward the end of the hot season, before the regular South-West Monsoon becomes established. The name is connected with the fact that these showers help mangoes to ripen in some areas. The reasoning is based on timing: summer heat continues; short rain showers occur; the main South-West Monsoon has not yet arrived; therefore these showers are called pre-monsoon rainfall. Option A is correct because before means prior to the arrival or regular onset of the South-West Monsoon. Option B is wrong because mango showers are not a winter phenomenon; they occur in the hot season. Option C is wrong because retreating monsoon comes after the main monsoon season, whereas mango showers come before it. Option D is wrong because they are not limited to the Himalayas and are strongly associated with southern India. Memory cue: mango showers come before the monsoon and help mangoes mature.

Correct answer: A. Strong storm and rain

The direct answer is option A: a strong storm and rain. A Norwester is a violent pre-monsoon thunderstorm, especially common in eastern and northeastern parts of India. In Bengal it is popularly called Kal Baisakhi. It can produce strong winds, thunder, lightning and heavy showers, and it may damage crops, houses and trees even though the rain can be useful. The reasoning is: Norwesters form during the hot pre-monsoon period; intense heating and unstable air help thunderstorms develop; the result is a sudden storm with rain. Option A is correct because stormy wind and rain are the characteristic weather of a Norwester. Option B is wrong because permanent snowfall is not a normal result of this hot-season thunderstorm. Option C is wrong because a Norwester is a short storm event, not a long spell of hot, dry Loo. Option D is wrong because the defining feature is rainfall and storm activity, not complete dryness. The term does not mean a dry northwesterly wind here; it refers to a local thunderstorm. Memory cue: Norwester or Kal Baisakhi means thunder, strong wind and rain before the monsoon.

Correct answer: A. It helps block cold Central Asian winds

The Himalaya helps reduce the direct effect of cold winds. Exam tip: connect Himalaya with climate control.

Correct answer: A. Covered with clouds

During the rainy season, the sky often appears covered with clouds because moist air rises, cools, and condenses into water droplets. These droplets gather to form clouds, and when they become sufficiently large, rain may fall. Monsoon weather is therefore commonly linked with cloudiness, high moisture, and rainfall. The sky may sometimes clear temporarily, but “often” does not mean that every hour or every day must be cloudy.

Option A is correct because a cloud-covered sky is a normal and visible feature of rainy-season conditions. Option B is wrong because the rainy season is not always completely clear. Option C describes dust rather than the main effect of moist monsoon air, and option D is more closely associated with clear night skies, not daytime rainy weather. The important connection is rainy season—moisture—clouds—rain.

Correct answer: A. Because temperature is high and sweating increases

In summer both people and crops may need more water. Exam tip: understand the link between summer and water demand.

Correct answer: A. Crops

Direct answer: Option A, crops. Frost means a thin layer of ice formed when the temperature near the ground falls to or below freezing. Step by step: winter brings very low temperatures; water in or on plant tissues may freeze; freezing can injure leaves, flowers and young plants; therefore some crops suffer damage. Option A is correct because crops are living plants that can be harmed by frost. Option B, the sea, is a large water body and is not the usual agricultural object meant by this question. Option C, loo, is a hot, dry summer wind, not something frost damages. Option D, a cyclone, is a weather system, not a crop or object normally described as being damaged by frost. The exact damage depends on the crop and its stage of growth. Memory cue: frost is cold danger for fields; loo is hot danger in summer.

Correct answer: A. Drought and crop stress

Low monsoon rainfall can affect both water and crops. Exam tip: connect weak monsoon with farming problems.

Correct answer: A. Flood

Excess monsoon rain can raise river water levels and cause floods. Exam tip: remember risks of excess rainfall.

Correct answer: A. From north-west India

Monsoon withdrawal generally starts from north-west India. Exam tip: remember onset and withdrawal sequence separately.

Correct answer: A. From the south-west direction

The South-West Monsoon enters India from the Kerala coast. Exam tip: connect onset with south-west direction and Kerala.

Correct answer: A. Cold and foggy

Winter mornings in North India can be cold and foggy. Exam tip: remember local features of winter.

Correct answer: A. Because of intense heat and Loo

Summer afternoon heat and Loo can harm health. Exam tip: understand the relation between weather and health.

Correct answer: A. When heavy rain and poor drainage occur

Heavy rain and poor drainage cause waterlogging. Exam tip: remember the relation between rainy season and drainage.

Correct answer: A. It can become a source of cyclones

Cyclones can form in the Bay of Bengal during retreating monsoon. Exam tip: connect it with eastern coast risk.

Correct answer: A. Sowing harvesting and irrigation timing depend on seasons

Farm work is linked with seasonal changes in temperature and rainfall. Exam tip: remember seasons and farm planning.

Correct answer: A. Help in ripening mangoes

Mango showers are pre-monsoon rains that occur in parts of southern India during the hot weather season. They are called mango showers because their timing and moisture are considered helpful for the development and ripening of mangoes. These rains may also provide some relief from intense heat and support certain local crops, although their amount can vary.

Option A is correct because it identifies the traditional agricultural benefit associated with these showers. They do not increase the loo, dry crops, or freeze the sea. The term should be remembered with its seasonal setting and crop connection: hot-season pre-monsoon rain can help mango production. This is a local weather event, so it should not be confused with the main southwest monsoon rainfall that supports broad kharif cultivation.

Correct answer: A. Jute

Rain from Kal Baisakhi can help crops like jute in eastern India. Exam tip: connect it with local rain of Bengal.

Correct answer: A. From the west

Western disturbances come from the west and bring rain to north-west India. Exam tip: remember the direction from the name.

Correct answer: A. They may fill less

Low monsoon rainfall can reduce water stored in reservoirs. Exam tip: connect rainfall with water storage.

Correct answer: A. Cold hot rainy and retreating monsoon are the main seasons

India's main seasons are identified by changes in temperature wind and rainfall. Exam tip: remember features of all four seasons.

Correct answer: C. 50% (50 प्रतिशत)

The correct answer is C: 50%. Relative humidity tells us how much water vapour is actually present in the air compared with the greatest amount the air could hold at the same temperature. The formula is: relative humidity = (actual vapour pressure ÷ saturation vapour pressure) × 100. Here the actual vapour pressure is 15 and the saturation vapour pressure is 30. Therefore, relative humidity = (15 ÷ 30) × 100 = 1/2 × 100 = 50%. This means the actual vapour pressure is half the saturation vapour pressure. Option A, 30%, would require the ratio to be 0.30. Option B, 40%, would require an actual pressure of 12 out of 30. Option D, 60%, would require an actual pressure of 18 out of 30. A useful memory cue is “actual over saturation, then multiply by 100.” Do not reverse the two pressures, because that would give an incorrect value.
