FAQs on Unit Test: Climates of India - Social Science Class 7 - New NCERT

1. What are the major climatic regions of India?
Ans. India has diverse climatic regions that can be broadly categorized into four major types: tropical, arid, temperate, and alpine. The tropical climate is predominant in the southern part of the country and is characterized by high temperatures and heavy rainfall. The arid climate is found in the western regions, such as Rajasthan, where there is little rainfall and high temperatures. The temperate climate is present in the northern plains and hilly areas, with distinct seasons. Lastly, the alpine climate can be found in the Himalayan region, characterized by cold weather and snowfall.
2. How does the monsoon season affect the climate of India?
Ans. The monsoon season, which typically occurs from June to September, plays a crucial role in shaping the climate of India. It brings heavy rainfall, especially to the western coast and northeastern states, which is essential for agriculture. The arrival of monsoon winds leads to a drop in temperature and increases humidity. However, the distribution of rainfall can be uneven, leading to droughts in some regions and floods in others, significantly impacting the livelihood of farmers and the overall economy.
3. What are the main factors influencing the climate of India?
Ans. Several factors influence the climate of India, including latitude, altitude, distance from the sea, and the monsoon winds. Latitude affects the temperature, with regions closer to the equator being warmer. Altitude plays a role in temperature variations, with higher altitudes experiencing cooler climates. The proximity to the sea moderates temperatures, while the monsoon winds bring seasonal changes in weather patterns. Additionally, the Himalayas act as a barrier to cold winds from the north, influencing the climatic conditions in northern India.
4. What is the significance of the Western Ghats in India's climate?
Ans. The Western Ghats significantly affect India's climate by influencing the monsoon patterns. They act as a barrier to the southwest monsoon winds, causing heavy rainfall on the windward side, while the leeward side remains relatively dry. This results in a lush green landscape in the western coastal regions, while areas like the Deccan Plateau receive less rainfall. The Western Ghats also play a crucial role in maintaining biodiversity and regulating the local climate, making them an important ecological zone.
5. How do human activities impact the climate of India?
Ans. Human activities, such as deforestation, urbanization, and industrialization, have a significant impact on India's climate. Deforestation leads to a loss of vegetation, which can result in increased temperatures and decreased rainfall. Urbanization contributes to the urban heat island effect, raising temperatures in cities. Additionally, industrial emissions contribute to air pollution and climate change, exacerbating weather extremes like heatwaves and floods. Sustainable practices are essential to mitigate these effects and protect the climate.
