First and foremost, the Earth’s atmosphere comprises a layer of gases (also referred to as air) which forms an envelope around Earth. The atmosphere is stratified into five (5) layers which are as follows: The exosphere, the thermosphere, the mesosphere, troposphere and the stratosphere. This envelope of gases is retained around Earth by the influence…
The Ozone Layer is an important element in the history of life on earth. Without it, many living things probably would not exist and the earth would be extremely different. Millions of years ago, only single cell creatures existed on earth. At that time, the earth had no oxygen that would support life. But as…
Since childhood, we have been studying the solar system and making models of it. But there is still a lot of interesting facts about the solar system that we have never known. With new technologies springing up every minute we turn out heads, we get to study the solar system with more accuracy, clarity, and…
Mars is one of the most intriguing planets in the solar system. It’s filled with mysteries, including huge canyons approximately 3000 miles across and 6,000 miles deep, volcanoes about 75,000 feet tall, and other fascinating sceneries in our solar system. Water once rule this planet, then disappeared into thin air. With that in mind, let’s…
Life on Earth has been protected for thousands of years with a vital layer of poison in the atmosphere. This layer serves as a shield that protects the Earth from harmful ultraviolet radiation from the sun. As far as we know, it is unique to our planet. If it disappeared, ultraviolet sunlight would sterilize the…
The Ozone layer is a deep blanket in the stratosphere made up of comparatively high concentration of the ozone. As a result of its chemical composition, ozone is regarded as a special type of oxygen as it contains three oxygen molecules (O3) as opposed to the usual two oxygen molecules (O2). The ozone layer encircles…
The atmosphere is the mass of air surrounding the earth. It’s constitutes a mixture of nitrogen (about 78%), oxygen (about 21%), and other gasses (about 1%) such as carbon dioxide (0.039%), argon (0.93%) and the rest are trace gases (krypton, neon, helium , and xenon). The mass of the atmosphere totals to about 5.15×1018 kg. Higher…
Air pollutants can potentially harm human and animal health, damage or hinder vegetation growth, and can make the living conditions in the environment unbearable. In most regions of the world, air pollution has adversely affected people and the environment in various aspects. The short-term and long-term effects of air pollution as experienced across the world…
Pollution is the contamination of the environment by introduction of contaminants that can cause damage to environment and harm or discomfort to humans or other living species. It is the addition of another form of any substance or form of energy to the environment at a rate faster than the environment can accommodate it by…
Climate change and global warming are hot topics these days. Studies conducted by various scientists suggest that climate change is happening and it could have devastating and damaging effects on human life. So, what is climate change? Due to burning of fossil fuels, the atmospheric concentrations of carbon dioxide have increased significantly. Though presence of…
