(b) Why do places near the ocean have milder temperatures than places far away from it? Class 7
Answer:
Places close to the ocean have milder temperatures because the sea moderates the temperature. It absorbs heat slowly and loses heat slowly. Land absorbs heat quickly and loses rapidly. This keep places near the ocean keeping summers cooler and winters warmer compared to inland areas.
(c) What role do monsoon winds play in affecting India's climate? Class 7
Answer:
Summer monsoon winds are important for India's climate as they bring heavy rainfall during the summer months. This rain soaked the soil with water essential for agriculture, replenishing water sources and life thrives.
Winter monsoon are dry winds that bring cold weather to South India, but a part of them, passing over the Bay of Bengal, collect some moisture and bring rainfall to parts of east and south India.
(d) Why is Chennai warm or hot throughout the year, while Leh is cold? Class 7
Answer:
Chennai is warm throughout the year due to its low latitude (near the equator) and proximity to the sea, which keeps temperatures stable. In contrast, Leh is located in the mountains at a high altitude. At high altitude, the air is thinner and cannot hold much heat. This lowers the temperature, keeps the Leh cold.
