Diffusion and Osmosis

Diffusion and Osmosis are the two activities that preforms the role of transporting materials to or from the cell. Both are the passive transportation, that means such spontaneous process that does not needs any energy. The first one (diffusion) is the movements of molecules from the region of higher concentration ot the lower concentration trough […]


What are Particulates? Particulates, commonly known as Particulate Matter are basically small-sized particles that are present in the air. These particles can be present naturally in air or sometimes these are the result of man-made or anthropogenic activities. The particulates can either exist in the form of small solid particles or liquid droplets. There is […]


What is Leaching? The word ‘leaching’ in reference to the chemical industry corresponds to the removal of chemicals. It is quite a traditional method that involves solid-liquid operation. Traditionally it was regarded as percolation. Leaching is a process where a mixture is diffused or dissolved in liquid in order to separate the solute. More simply, […]

Radioactive Waste

What is Radioactive Waste? Radioactive waste, also regarded as nuclear waste is basically such unwanted material or substance that has a high concentration of radionuclides. The nuclear substances over here can occur either naturally or can be the outcome of various man-made activities. The term radionuclide corresponds to the nuclide that has a large amount […]

Oxygen Cycle

­­What is Oxygen Cycle? The oxygen cycle tells us about the way the exchange of oxygen takes place in between various environmental segments such as the atmosphere, lithosphere, hydrosphere, and biosphere. Oxygen is a well-known byproduct of the process of photosynthesis. It is one of the elements that exist in ample amounts on the Earth. […]


What is Eutrophication? A process or technique that helps to enhance the constituent amount of nutrients in water bodies is known as Eutrophication. The word ‘eutrophication’ is arrived from the Greek word ‘eutrophos’ that means nourished or enriched. The enrichment in water bodies somewhat increases the rate of production of phytoplankton and microphytes within the […]

Environmental Chemistry

What is Environmental Chemistry? The field that deals with the study of various chemical processes occurring in the different elements of the environment such as water, air, land, and the effects of numerous human activities on these parameters. It is basically associated with the various chemicals such as organic, biochemical, etc. existing in the environment. […]


What is an Ecosystem? The word ecosystem is defined as a unit of nature that includes living organisms along with the physical environment interacting with each other. An ecosystem can be as small as a small pond or as large as a sea. The whole ecosystem is mainly classified into two categories namely, terrestrial and […]


What are Aerosols? Aerosols sometimes referred to as atmospheric aerosols are the tiny particles existing in either solid, liquid, or both forms that are suspended in the air. The diameter of these particulate matter ranges between 0.002 µm and 100 µm. The major natural sources of aerosols are dust, sea spray, etc. whereas anthropogenic sources […]

Layers of Atmosphere

Layers of Earth’s Atmosphere There are various properly marked horizontal layers of the atmosphere that are divided according to the temperature at different parts of the earth’s atmosphere. Mainly, there are five layers of atmosphere namely: Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere Before discussing each individual layer of the atmosphere. Let us see What is […]
