Important Questions (1 mark): Climate - Question 14

Which of the following prevents the southwest monsoon winds from escaping from India? 

Detailed Solution for Important Questions (1 mark): Climate - Question 14
The Himalayas
The Himalayas act as a physical barrier that prevents the southwest monsoon winds from escaping from India. Here is a detailed explanation:
- Southwest Monsoon Winds: The southwest monsoon winds are a seasonal wind pattern that brings heavy rainfall to India during the summer months. These winds originate over the Indian Ocean and move towards the Indian subcontinent.
- Barrier Effect of the Himalayas: The Himalayas, which are a mountain range in northern India, act as a barrier to the southwest monsoon winds. As the winds approach the Himalayas, they are forced to rise due to the high elevation of the mountains.
- Orographic Effect: The rising air encounters cooler temperatures at higher altitudes, causing it to condense and form clouds. This leads to the formation of heavy rainfall on the windward side of the mountains. As a result, most of the rainfall brought by the southwest monsoon winds is concentrated on the windward side of the Himalayas, while the leeward side experiences a rain shadow effect with less rainfall.
- Preventing Escape: The rising air and heavy rainfall on the windward side of the Himalayas create a low-pressure system over northern India. This low-pressure system acts as a barrier, preventing the southwest monsoon winds from escaping from India. The winds are trapped within the subcontinent, resulting in the widespread distribution of rainfall across the country.
In summary, the Himalayas act as a physical barrier that forces the southwest monsoon winds to rise, leading to heavy rainfall on the windward side and preventing their escape from India.
Important Questions (1 mark): Climate - Question 15

Detailed Solution for Important Questions (1 mark): Climate - Question 15
Reasons why southwest monsoons are rain-bearing winds:

  • They blow over warm Indian Ocean and gather moisture: The southwest monsoon winds originate over the Indian Ocean, where they pick up moisture due to the warm temperatures of the ocean. This moisture-laden air is then carried towards the Indian subcontinent, leading to rainfall.

Important Questions (1 mark): Climate - Question 16

From which of the following pressure belts do the north-easterly trade winds originate?

Detailed Solution for Important Questions (1 mark): Climate - Question 16
The Origin of North-Easterly Trade Winds
The north-easterly trade winds originate from the Subtropical high pressure belt of the Northern Hemisphere. Here is a detailed explanation of why this is the correct answer:
1. Trade Winds: Trade winds are the prevailing winds that blow from east to west between the equator and the subtropical high-pressure belts at about 30 degrees latitude.
2. Pressure Belts: Pressure belts are regions of the Earth's atmosphere where air pressure is relatively high or low. They are caused by the uneven heating of the Earth's surface.
3. Subtropical High Pressure Belt of the Northern Hemisphere: This pressure belt is located around 30 degrees latitude in the Northern Hemisphere. It is created by the sinking air from the Hadley Cell circulation, which is a global atmospheric circulation pattern.
4. Coriolis Effect: The Coriolis effect, caused by the Earth's rotation, deflects the trade winds to the right in the Northern Hemisphere. This deflection causes the north-easterly direction of the trade winds.
5. Origin of North-Easterly Trade Winds: The north-easterly trade winds originate from the subtropical high pressure belt of the Northern Hemisphere due to the combined effect of the pressure gradient and the Coriolis effect.
Therefore, the correct answer is B: Subtropical high pressure belt of the Northern Hemisphere.

Important Questions (1 mark): Climate - Question 18

Which of the following winds brings widespread rainfall over the mainland of India?

Detailed Solution for Important Questions (1 mark): Climate - Question 18
Explanation:

  • Southwest monsoon winds: The southwest monsoon winds are responsible for bringing widespread rainfall over the mainland of India. These winds originate over the Indian Ocean and bring moisture-laden air over the subcontinent, resulting in heavy rainfall during the monsoon season.

  • Northeasterly winds: These winds generally bring dry weather over most parts of India and are not associated with widespread rainfall.

  • Westerlies: The westerlies bring rainfall to the northern parts of India during the winter season but are not the primary source of widespread rainfall over the mainland.

  • Sea breeze: Sea breeze is a local wind phenomenon that occurs along coastal areas and does not bring widespread rainfall over the mainland of India.

Important Questions (1 mark): Climate - Question 19

Which of the following atmospheric conditions govern the climate and associated weather conditions in India?

Detailed Solution for Important Questions (1 mark): Climate - Question 19
Atmospheric Conditions Governing Climate and Weather in India:
India's climate and associated weather conditions are influenced by several atmospheric conditions. These include:
1. Pressure and Surface Winds:
- Pressure systems: The pressure systems in the atmosphere, such as the high-pressure area over the Indian Ocean and low-pressure area over the Indian subcontinent, determine the movement of air masses.
- Monsoonal winds: The seasonal reversal of winds, known as the monsoon winds, is a significant factor in Indian weather. The southwest monsoon brings heavy rainfall to most parts of India, while the northeast monsoon affects the southeastern coast.
2. Upper Air Circulation:
- Jet streams: The position and intensity of the jet streams, which are high-speed winds in the upper atmosphere, affect the movement of weather systems and the distribution of rainfall in different regions of India.
- Troughs and ridges: The presence of troughs (elongated areas of low pressure) and ridges (elongated areas of high pressure) in the upper-level atmospheric circulation influences the development of weather systems and precipitation patterns.
3. Western Cyclonic Disturbances and Tropical Cyclones:
- Western cyclonic disturbances: These are weather systems that originate in the Mediterranean region and move eastwards, affecting the weather in northern India during the winter months. They bring rainfall and snowfall to the Himalayan region.
- Tropical cyclones: These intense low-pressure systems form over warm ocean waters and can impact coastal regions of India. They bring heavy rainfall, strong winds, and storm surge.
Conclusion:
All of the above atmospheric conditions, namely pressure and surface winds, upper air circulation, and the influence of western cyclonic disturbances and tropical cyclones, play a vital role in governing the climate and associated weather conditions in India. These factors interact with each other to determine the temperature, rainfall, and wind patterns experienced in different parts of the country.

Important Questions (1 mark): Climate - Question 25

Latitude and altitude of a place determine which of the following climatic elements of a place?

Detailed Solution for Important Questions (1 mark): Climate - Question 25

Latitude and altitude can both influence the climate of a place. Latitude refers to the distance of a place north or south of the equator, while altitude refers to the height of a place above sea level.

Latitude can influence the climate of a place by determining the amount of sunlight that a place receives. Places closer to the equator receive more direct sunlight throughout the year and have warmer climates, while places farther from the equator receive less direct sunlight and have cooler climates.

Altitude can also influence the climate of a place by affecting the amount of sunlight and heat that a place receives. Places at higher altitudes receive less sunlight and heat because they are farther from the warming effects of the earth's surface. As a result, higher altitude places tend to have cooler climates.

Therefore, the correct answer is 2.
