Combustion and Incineration: A Comprehensive Overview Combustion and incineration are two closely related processes that involve the rapid chemical reaction between a substance and an oxidant, typically oxygen, producing heat and light. While both processes involve burning, they differ in their applications, objectives, and environmental implications. This article delves into the intricacies of combustion and … Read more
Concept Definition Carbon Sequestration Carbon sequestration is the process of removing carbon from the Atmosphere and storing it in a fixed molecule in Soil, Oceans or Plants. Carbon Sink An organism or landscape that stores carbon is called a carbon sink. Carbon source An organism or landscape that emits carbon is called a carbon source. Climate change adaptation … Read more
What is Geothermal Energy? Geothermal energy is heat from the Earth’s interior that can be used to generate electricity, heat homes and businesses, and provide hot water. The Earth’s core is very hot, about 6,000 degrees Fahrenheit (3,300 degrees Celsius). This heat comes from the decay of radioactive elements in the core. The heat travels … Read more
