Below are the detailed answers to all questions and activities provided in the chapter "Weather and Climate" from the Kerala Social Science 2 Textbook. The responses are structured to address each question and activity comprehensively, ensuring clarity and relevance for exam preparation.
Some examples:
1. What are Green Houses? Inquire.
Answer: Greenhouses are structures made of glass or plastic designed to trap heat and create a controlled environment for growing plants. They allow sunlight to enter, warming the interior, while
preventing heat from escaping, mimicking the atmospheric greenhouse effect. In the atmosphere, gases like carbon dioxide trap terrestrial radiation, maintaining Earth’s temperature. Similarly,
greenhouses maintain warm conditions, enabling year-round cultivation of crops, even in cold climates. They are used in agriculture to grow vegetables, flowers, and fruits, protecting plants from
adverse weather and pests while optimizing growth conditions.
2. Is the distribution pattern of isotherms shown in the map uniform? You might have noticed that the temperature gradually decreases while moving away from the equator.
Answer: The distribution pattern of isotherms is not uniform. Isotherms, which connect places with equal temperatures, show a general trend of decreasing temperature from the equator to the poles
due to the angle of solar rays. Near the equator, vertical rays cause higher temperatures, while oblique rays at higher latitudes result in lower temperatures. However, the pattern is disrupted by
factors like land-sea distribution, ocean currents, and relief. For example, isotherms bend at land-sea interfaces because land heats and cools faster than water, creating temperature contrasts. In the
Southern Hemisphere, isotherms are more parallel to latitudes due to extensive ocean coverage, which moderates temperature variations. These non-uniform patterns reflect the complex interplay
of factors influencing global temperature distribution.
