Biogas- principle and process Principle of biogas production Biogas is generated when bacteria degrade biological material in the absence of Oxygen, in a process known as Anaerobic Digestion. Since biogas is a mixture of methane (also known as marsh gas or natural gas, CH4) and carbon dioxide it is a renewable fuel produced from waste … Read more
The Greenhouse Effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s Atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. It is the process by which radiation from a planet’s atmosphere warms the planet’s surface to a … Read more
Elements of Climate and weather Climate is decided by a region’s climate system. A climate system has few major components: the Atmosphere, the layer, the cryosphere, and the land surface. The atmosphere is that the most variable a part of the climate system. The composition and movement of gases encompassing the planet will change … Read more
The Invisible Shield: Composition of the Atmosphere and Its Vital Role The Earth’s atmosphere, a seemingly invisible blanket enveloping our planet, plays a crucial role in sustaining life. It acts as a protective shield, regulating temperature, filtering harmful radiation, and facilitating weather patterns. Understanding the composition of this vital layer is essential for comprehending its … Read more
Methane: A Potent Greenhouse Gas with a Complex Story Methane (CH4), a colorless, odorless gas, is a potent greenhouse gas (GHG) that plays a significant role in global climate change. While less abundant in the atmosphere than carbon dioxide (CO2), methane is far more effective at trapping heat, making it a critical factor in understanding … Read more
The subtopics of greenhouse gases are: Carbon dioxide Methane Nitrous oxide Ozone Water vapor Fluorinated gases Carbon dioxide is the most important greenhouse gas because it is the most abundant. It is released into the atmosphere when fossil fuels are burned, such as coal, oil, and natural gas. Methane is the second most important greenhouse … Read more
The Greenhouse Effect: A Vital Balance Tipping Towards Crisis The Earth’s climate is a delicate dance, a complex interplay of energy flows, atmospheric composition, and natural cycles. At the heart of this dance lies the greenhouse effect, a natural phenomenon that keeps our planet habitable. However, human activities are disrupting this delicate balance, amplifying the … Read more
