Power resources are of two types: Conventional Resources: are those that have been in common use for a long time. Firewood and fossil fuels are two main conventional energy sources. Non-conventional Resources: of energy are renewable. Solar energy, wind energy, tidal energy, etc. are non-conventional sources of energy. Conventional power resources includes fossil fuels like […]
Minerals are basically non-renewable resources. They take thousands of years for the formation and concentration of minerals. Some important minerals, like coal, were formed millions of years ago. Most of the oil found in the crust of the Earth were also formed millions of years ago, but some very small amount were formed only a
Different regions have access to different renewable or nonrenewable natural resources such as freshwater, fossil fuels, fertile soil, or timber based on their geographic location and past geologic processes. Access, or the lack thereof, contributes to a place’s economic development, political relationships, and culture. For example, the Great Plains region of the United States is
Mineral resources can be divided into two major categories – Metallic and Nonmetallic. Metallic resources are things like Gold, Silver, Tin, Copper, Lead, Zinc, Iron, Nickel, Chromium, and Aluminum. Nonmetallic resources are things like sand, gravel, gypsum, halite, Uranium, dimension stone. (i) Metallic resources are things like Gold, Silver, Tin, Copper, Lead, Zinc, Iron, Nickel,
Minerals are naturally occurring substances that have a definite chemical composition. Minerals are distinct from rocks, which are too complex to characterize with a simple composition. More or less, a rock is a collection or cluster of many minerals. Minerals are formed in different types of geological environments, under varying conditions. Minerals vary from element
Forests are the most vital yet fragile part of our planet. They not only provide food and shelter to us but also help maintain a healthy ecosystem of plants and animals. The maintenance or loss of forest land is very critical in understanding climate changes. Forests help in maintaining the normal levels of oxygen, water
Vegetation is the foremost important component of the ecosystem. The growth of vegetation depends on temperature and moisture. These are major necessities for the development of plants. Any deviation from this will be harmful to the growth of plants. Vegetation holds a significant position in ecological succession. If vegetation is destroyed, it can’t be reproduced
Natural vegetation and wildlife of the earth exist only in the biosphere. The plants of this vegetation are of two types: forest plants, trees of which shelter living creatures and also divide the earth into separate habitats; and grass plants such as meadow grasses, of which many kinds of herbivorous animals live. The types of
Water is a fascinating compound. It drives life on our planet and helps make it unique from other planets in the solar system. Without water, life wouldn’t be possible. Simple organisms, such as bacteria and even slime molds, need only a small number of water molecules to survive. On the other hand, large organisms such
It is difficult to determine whether water is scarce or not. Fresh water is found in lakes, rivers, underground reservoirs and the ocean. It is used for drinking, agriculture irrigation and many other purposes. Water shortage occurs due to overuse of fresh water sources. However, this shortage is not uniform throughout our environment. The shortage
