Water vapour evaporates from the surface of seas, lakes, and other bodies of water to form freshwater. When this vapour rises, salts and other impurities are left behind, and it becomes “fresh.” Water vapour condenses into drifting clouds, which eventually release the water back to Earth as rain or snow. When fresh water falls onto […]

Clearing huge regions of forest for mining operations, as well as for the mine itself and to accommodate infrastructure associated with mining operations, is a common requirement. Because of the cleaning of riparian vegetation, which is particularly prevalent around stream margins, when forests are cut down, habitat is lost to wildlife. These conditions can result

A fossil fuel is any of a class of hydrocarbon-containing compounds that are derived from biological sources and are found in the Earth’s crust and can be utilised as a source of electricity. Coal, petroleum, natural gas, oil shale, bitumen, tar sands, and heavy oils are examples of fossil fuels, as are coal-fired power plants.

Ecosystems can be extremely huge or extremely small. Tide pools, which are ponds left by the ocean as the tide recedes, are entire, miniature ecosystems. Tide pools contain seaweed, a type of algae that produces food through photosynthesis. Seaweed is eaten by herbivores such as abalone. Carnivores like sea stars devour other species in the

Forests are essential to our survival. We are all reliant on woods in some way for our survival. Forests offer us with clean air, food, medicines, and other resources such as timber, fodder, and other industrial raw materials. Forests help to keep the earth stable by preventing soil erosion.  Definition of a forest A forest

Forests cover a whopping 31% of the planet’s land area. It is estimated that 23% of India’s land area is covered by forest. An important part of the forest ecosystem is the presence of trees and plants. Clean air and shelter are essential for life on the planet. Forests also aid in the preservation of

Ecosystems are groups of living creatures and the physical environment in which they reside that collaborate to solve problems and communicate with one another and with the rest of the world. Environmentalists consider the entire globe to be a single ecosystem in which to live. Because the forest ecosystem is also a component of the

Weathering and erosion are processes that cause rocks to break down and migrate away from their original site. The distinction between weathering and erosion is dependent on whether or not the position of rock has changed: Weathering damages rocks without moving them, whereas erosion transports rocks and soil away from their original sites. Weathering frequently

There are numerous elements that contribute to or are influenced by our environment, which is the location where we humans, as well as other creatures, reside. These elements have combined to make the earth a safe haven for all of us. The two main elements, namely the abiotic factor and the biotic factor, work together

In the microbial world (and the non-microbial world, too!) competition is strong, and resources are limited. It can undoubtedly mean reduced competition for those microorganisms willing and able to adapt the tough environment. So, what factors influence microbial proliferation in the environment? The key ones include temperature, pH, oxygen, water activity, radiation, pressure, and nutrient deficiency. We’ll go over
