The Albedo of Earth: A Reflection on Our Planet’s Energy Balance The Earth, a vibrant and dynamic planet, is constantly bathed in energy from the sun. This solar radiation, the lifeblood of our planet, drives weather patterns, fuels ecosystems, and sustains life. However, not all of this incoming energy is absorbed. A significant portion is … Read more
The Equatorial Countercurrent: A Vital Force in the Ocean’s Circulation The Earth’s oceans are in constant motion, driven by a complex interplay of forces including wind, salinity, temperature, and the Earth’s rotation. This dynamic system creates a network of currents that transport heat, nutrients, and marine life across the globe. Among these currents, the Equatorial … Read more
Addition of certain substances to the water such as organic, inorganic, biological, radiological, heat, which degrades the quality of water so that it becomes unfit for use. Putrescibility is the process of decomposition of organic matter present in water by Microorganisms using Oxygen. Water having DO (dissolved oxygen) content below 8.0 mg/L may be … Read more
