(a) Warm days and warm nights
(b) Warm days and cold nights
(c) Cool days and cold nights
(d) Cold days and warm nights
Ans. (b) Warm days and cold nights

Q2. Answer the following questions briefly.

(i) What are the controls affecting the climate of India?

Ans. The factors affecting the climate of India are temperature, atmospheric pressure, wind, humidity and precipitation.

(ii) Why does India have a monsoon type of climate?

Ans. India have a monsoon type of climate because  the country’s climate is influenced by the monsoon winds or the changing weather conditions.

(iii) Which part of India does experience the highest diurnal range of temperature and why?

Ans. In certain places there is a wide difference between day and night temperature.  In the Thar Desert the day temperature may rise to 50°C, and drop down to near 15°C the same night. This is because it is filled with sand which gets heat up quickly during day and cooled up quickly during nights.

(iv) Which winds account for rainfall along the Malabar coast?

Ans. Malabar Coast gets rain from South-West Monsoon Winds.

(v) Define monsoons. What do you understand by “break” in monsoon?

Ans. Monsoon refers to the seasonal reversal in the wind direction during a year. A Monsoon Break occurs when there are few or no rains for a few days during the rainy season.

(vi) Why is the monsoon considered a unifying bond?

Ans. The word unifying bond is used in reference for monsoon because it binds the entire country together as it provides the much needed water to the agricultural activities. Every year farmers all around the country wait for the monsoon season so that their crops can get water.

Q3. Why does the rainfall decrease from the east to the west in Northern India.

Ans. Rainfall decreases from the east to the west in the Northern India because there is a decrease in the moisture content of the winds. As the moisture bearing winds of the Bay of Bengal Branch of the south west monsoon move further and further inland, the moisture gradually decreases and results in low rainfall when moving towards westwards.

Q4. Give reasons as to why.

(i) Seasonal reversal of wind direction takes place over the Indian subcontinent?

Ans. In winter, cold winds blow to south from the high-pressure area north of the Himalayas. In summer, the wind direction reverses as air moves from the southern Indian Ocean towards the low-pressure areas over the Indian subcontinent, bringing moisture and increased rainfall.

(ii) The bulk of rainfall in India is concentrated over a few months.

Ans. Monsoon are not steady winds but are pulsating in nature, affected by different atmospheric conditions. These winds are strong and blow at an average speed of 30 km/h. Barring the extreme northwest, they overrun from the country in a month’s time.

(iii) The Tamil Nadu coast receives winter rainfall.

Ans. Due to geographical location, the east coast receives rainfall as the north east trade winds blow from sea to land in this location. And all this happens in winter season.

(iv) The delta region of the eastern coast is frequently struck by cyclones.

Ans. Eastern coast gets its mostly rainfall from retreating monsoon. In November, the low-pressure conditions, over northwestern India, get transferred to Bay of Bengal produce cyclonic depression over the Andaman Sea. These cyclones generally cross the eastern coasts of India cause heavy and widespread rain.

(v) Parts of Rajasthan, Gujarat and the leeward side of the Western Ghats are drought-prone.

Ans. The regions of Rajasthan, Gujarat, and the leeward side of the Western Ghats are drought-prone due to factors such as rain shadows caused by mountain ranges, hindrance of south-westerly winds, and the topography of the Western Ghats. These areas receive less rainfall as moist air is intercepted or blocked, leading to water scarcity. The geological features, including basalt rocks and erosion, further contribute to their vulnerability to drought.

Q5. Describe the regional variations in the climatic conditions of India with the help of suitable examples.

Ans. India showcases significant regional variations in climatic conditions. During summer, temperatures can soar above 50°C in Rajasthan’s desert, while Pahalgam in Jammu and Kashmir may enjoy around 20°C. Winter nights in Dassin, Jammu and Kashmir, can plummet to -45°C, whereas Thiruvananthapuram may maintain a mild +20°C. Certain areas experience drastic day-to-night temperature differences, like the Thar Desert with scorching days and near-freezing nights. Conversely, the Andaman and Nicobar Islands and Kerala witness minimal temperature fluctuations. Precipitation predominantly takes the form of snowfall in the upper Himalayas, while the rest of the country receives rainfall. Annual rainfall ranges from 400 cm in Meghalaya to under 10 cm in Ladakh and Western Rajasthan. Additionally, while most regions receive rainfall from June to September, the Tamil Nadu coast experiences it during autumn and early winter. These climatic variations contribute to India’s diverse weather patterns.

Q6. Give an account of weather conditions and characteristics of the cold season.

Ans. Weather conditions in winter are :

During the winter season in India, the northeast trade winds prevail. The coldest months in North India are January and December. The cold weather season starts in mid-November and lasts until February in Northern India, accompanied by snowfall in the higher slopes of the Himalayas. The temperature gradually decreases as one moves from Southern to Northern India. It is a dry season in most parts of the country, with variable and feeble winds, low temperatures, and clear skies. The Peninsular region experiences a milder winter due to the moderating influence of the sea.

Characteristics : –

As Western disturbances move into India, cause winter rains over plains and snowfall in the mountains. They are of much importance for the cultivation of rabi crops.

Q7. Give the characteristics and effects of the monsoon rainfall in India.

Ans. Characteristics of monsoon rainfall in India are as follow –

Indian climate is a monsoon type climate. The characteristics feature of the monsoon rainfall is characterised by weather condition that change from season to season.  Monsoon rainfall duration varies from 100 to 120 days. Monsoon has characteristic wet and dry spells or “breaks in rainfall”.

Effects of monsoon rainfall in India:

(a) Indian agriculture is largely dependent upon the water from the monsoon rains. Late, low or excessive rains have a negative impact upon crops.

(b) Due to the uneven distribution of rainfall across the country, there are some regions that are drought prone and some that are flood afflicted.

(c) The monsoon provides India with a distinct climatic pattern. Hence, in spite of the presence of great regional variations, it has a unifying influence upon the country and its people.


On an outline map of India, show the following.

(i) Areas receiving rainfall over 400 cm.

(ii) Areas receiving less than 20 cm of rainfall.

(iii) The direction of the south-west monsoon over India.



(i) Find out which songs, dances, festivals and special food preparations are associated with certain seasons in your region. Do they have some commonality with other regions of India?

(ii) Collect photographs of typical rural houses, and clothing of people from different regions of India. Examine whether they reflect any relationship with the climatic condition and relief of the area.

Ans. Do it yourself.
