Ozone (O3) is a molecule made up of three atoms of Oxygen (O), and is mostly found in the strato- sphere, where it protects us from the Sun’s harmful ultraviolet (UV) radiation. Although it represents only a tiny fraction of the Atmosphere, ozone is crucial for life on Earth. The stratospheric ozone layer forms a … 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
Chlorofluorocarbons (CFCs) are a group of man-made chemicals that were once widely used in refrigerators, air conditioners, and aerosol cans. CFCs are very stable and do not break down easily in the atmosphere. When CFCs reach the upper atmosphere, they are broken down by ultraviolet radiation and release chlorine atoms. Chlorine atoms react with ozone … Read more

Ozone Depleting Substances (ODS) are substances that can deplete the ozone layer in the Earth’s stratosphere. The ozone layer is a region of Earth’s stratosphere that absorbs most of the Sun’s ultraviolet radiation. It contains high concentrations of ozone (O3) relative to other parts of the atmosphere, although still small in relation to other gases … 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 is a natural process that warms the Earth’s surface. When sunlight hits the Earth’s atmosphere, some of the energy is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the Earth’s atmosphere and surface. The greenhouse effect is essential to life on Earth. … Read more
