Short/Long Answer Type Questions(3/5 marks)

Q1. What are the reasons behind the variety in lives of people – in terms of the food, clothes and houses?

Ans.

• variation in temperature
• variation in atmospheric pressure
• variation in wind
• variation in humidity
• variation in precipitation

Q2. Describe the major controls of the climate?

Ans. There are six major controls of the climate of any place. They are:

• Latitude,
• Altitude,
• Pressure and wind system,d. Distance from the sea
• Ocean currents
• Relief features

Q3. Discuss the role of earth’s curvature in influencing climatic condition of a place.

Ans.

• The amount of solar energy received varies according to latitude.
• Air temperature generally decreases from the equator towards the poles
• Atmosphere becomes less dense and temperature decreases.

Q4. What are the factors affecting climate of the india?

Ans.

• Latitude
• Altitude
• Pressure and Winds

Q5. “The pressure and wind conditions over India are unique.” Elaborate.

Ans.

• During winter: High-pressure area north of the Himalayas, Cold dry winds blow from this region to the low-pressure areas over the oceans to the south.
• In summer: A low-pressure area develops over interior Asia as well as over northwestern India. This causes a complete reversal of the direction of winds during summer.

Q6. How many seasons are experienced in the India?

Ans. Four main seasons can be identified in India –

Q7. Analyse the role of Himalayas in influencing the climate of India.

Ans.

• Himalayas effectively intercept the summer monsoons coming from the Bay of Bengal and Arabian sea and cause precipitation in form of rain or snow
• Himalayas prevent the cold continental air masses of central asia form entering to india
• Himalayas are responsible for splitting the jet stream in to two branches.

Q8. Discuss the conditions of retreating monsoon.

Ans.

• Retreating monsoon is the period of transition
• during transition low pressure of the north-west shifts to the Bay of Bengal
• formation of cyclones over the Bay of Bengal

Q9. ‘In spite of abundant rainfall, India is a water thirsty land’. Why is it so?

Ans.

• occurrence of rainfall in a few months
• rapid run off and the quick evaporation of rainwater
• long breaks and delays in the monsoon

Ans.

• during monsoon pass, thar desert become warmer and increase their capacity to hold moisture instead of shedding moisture.
• Aravalli hills fall parallel to the Arabian sea and they do not act as barrier.

Q11. Why are the great variations in the climate of the India?

Ans. The Indian climate is controlled by the following factors:

• Situation
• Relief
• Surface winds
• Upper current

Q12. Describe the three main characteristics of the monsoon.
