Below are detailed answers to all questions and activities from the chapter "Climatic Regions and Climate Change" from the Kerala 10th std Social Science 2 Textbook. The responses address each question and activity comprehensively, tailored for student understanding and exam preparation.
It includes:
Why does this difference in diurnal range of temperature occur in the Monsoon climatic region?
Answer: In the Monsoon climatic region, the diurnal range of temperature (difference between day and night temperatures) is low in coastal areas and high in interior areas due to geographical factors. Coastal areas, like Kerala, are close to the sea, which has a high specific heat capacity, meaning it absorbs and releases heat slowly. This moderates temperatures, keeping day and night temperatures relatively stable. In contrast, interior areas, far from the sea, lack this moderating effect. Land heats up quickly during the day and cools rapidly at night, leading to a higher diurnal range. Additionally, high humidity in coastal areas traps heat, further reducing temperature fluctuations.
Does convectional rainfall occur in the Monsoon climatic region?
Answer: Yes, convectional rainfall occurs in the Monsoon climatic region, though it is less dominant than monsoon rainfall. Convectional rainfall happens when high temperatures heat the ground, causing air to rise, cool, and condense into rain, typically in the afternoon. In the Monsoon region, especially during summer, high temperatures and humidity can trigger convectional rainfall, particularly in interior areas. However, the primary rainfall in this region comes from monsoon winds, which bring heavy, seasonal rains from June to September.
