FAQs on Important Points - Weather, Climate and Adaptations of Animals to Climate - Class 7

1. How does weather differ from climate?
Ans. Weather refers to the short-term conditions of the atmosphere, such as temperature, humidity, precipitation, and wind, that occur in a specific area over a short period of time. On the other hand, climate refers to the long-term average weather conditions of a particular area, including temperature, rainfall patterns, and seasonal variations, typically measured over a period of 30 years or more.
2. What are the factors that determine climate?
Ans. Climate is determined by several factors, including latitude, altitude, distance from the sea, ocean currents, prevailing winds, topography, and the presence of natural features such as mountains or large bodies of water. These factors influence the amount of solar radiation received, the distribution of heat and moisture, and the overall weather patterns in a particular region.
3. How do animals adapt to different climates?
Ans. Animals adapt to different climates through various physiological, behavioral, and morphological adaptations. Physiological adaptations include changes in metabolism, body size, and insulation to regulate body temperature. Behavioral adaptations involve migration, hibernation, or changing activity patterns to cope with seasonal variations. Morphological adaptations include features like thick fur, long beaks, or large feet that help animals survive in specific climates.
4. What is the importance of climate for animals?
Ans. Climate plays a crucial role in shaping the habitats and ecosystems in which animals live. It determines the availability of food, water, and shelter, which are essential for their survival. Climate also influences the breeding patterns, migration routes, and overall distribution of animal species. Any significant changes in climate can have a profound impact on the survival and reproductive success of animals.
5. How do animals adapt to extreme weather conditions?
Ans. Animals adapt to extreme weather conditions by employing various strategies. Some animals have physical adaptations, such as thick fur or blubber, to withstand cold temperatures. Others have specialized body parts, like long legs or webbed feet, to navigate flooded areas during heavy rain. Some animals can enter a state of dormancy or hibernation to conserve energy during extreme heat or cold. Additionally, many animals seek shelter in burrows, caves, or other protected habitats to avoid harsh weather conditions.
