FAQs on Major Water Bodies Video Lecture - Geography Class 6 ICSE

1. What are the major water bodies in the world?
Ans. The major water bodies in the world include oceans, seas, rivers, lakes, and glaciers. The five largest oceans are the Pacific, Atlantic, Indian, Southern, and Arctic Oceans. Important seas include the Mediterranean Sea and the Caribbean Sea. Major rivers such as the Nile, Amazon, and Yangtze play a crucial role in ecosystems and human civilization. Lakes like the Great Lakes in North America and the Caspian Sea are also significant water bodies.
2. How do water bodies affect climate?
Ans. Water bodies play a vital role in regulating the climate. They absorb heat from the sun, which helps moderate temperatures in nearby areas. Oceans and large lakes can influence weather patterns by providing moisture to the atmosphere, leading to precipitation. The presence of water bodies can also lead to milder winters and cooler summers in coastal areas.
3. Why are rivers important for human life?
Ans. Rivers are essential for human life as they provide fresh water for drinking, agriculture, and sanitation. They serve as transportation routes for trade and commerce, and many cities are located along riverbanks due to the resources they offer. Additionally, rivers support diverse ecosystems and provide habitats for various species.
4. What is the difference between a lake and a pond?
Ans. The main difference between a lake and a pond is their size. Lakes are generally larger and deeper than ponds. Lakes can support larger ecosystems and are often more stratified, meaning they have distinct layers of temperature and oxygen. Ponds are shallower and typically allow sunlight to penetrate to the bottom, supporting a different type of aquatic life.
5. How do glaciers contribute to water supply?
Ans. Glaciers are significant sources of fresh water, especially in regions where they melt during warmer months. As glaciers slowly melt, they release water that flows into rivers and lakes, providing essential water supplies for communities and ecosystems. Glaciers also act as natural reservoirs, storing water over long periods and releasing it gradually.
