What is Gases In The Atmosphere?

Gases in the atmosphere are made up of nitrogen, oxygen, water vapor and trace gases. These different components make up air pollution, which can have a negative effect on both human health and the environment. Nitrogen is an essential element for all living things on earth as it makes up 78 percent of the Earth’s atmosphere. It plays a vital role in photosynthesis and helps to regulate temperatures by absorbing radiation from the sun. Oxygen accounts for 21 percent of our atmosphere and is responsible for sustaining life on Earth by providing us with necessary oxygen to breathe. Water vapor exists in variable amounts depending on local environmental conditions including temperature and moisture levels; however, it generally ranges between 0-4 percent of the atmosphere’s composition. Trace gases such as carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) make up less than 1 percent of our atmosphere but still play important roles such as regulating global climate systems, influencing weather patterns and contributing to ozone depletion when found at higher concentrations due to human activities like burning fossil fuels or deforestation. The presence of these different atmospheric gases can have significant consequences for human health if their concentrations become too high or too low relative to normal levels. For example, elevated CO2 levels can lead to increased respiratory issues due to inhalation of pollutants while decreases in oxygens concentration leads to hypoxia which may cause dizziness or other problems related insufficient oxygen supply being delivered throughout your body. In addition, changes in atmospheric gas compositions can also adversely affect crops leading them more susceptible pests or diseases as well as negatively impacting soil health over time if not properly monitored or managed according oxidative capacity tests conducted regularly within agricultural communities around world today.
