List Any Three Human Activities That You Think Would Lead to Air Pollution.Īns: Three human activities that would lead to air pollution are deforestation, automobile emissions, and industrialisation all contribute to the combustion of fossil fuels.Īns: Organisms need water as all the cellular processes need water as a medium. Clouds arise as a result of the production of water droplets.ĥ.
Water droplets develop as a result of the condensation of water vapour.
When water vapour-carrying air rises, it expands and cools. The air in the atmosphere heats up as a result of this. The air then travels from a high-pressure area to a low-pressure area, creating wind.Īns: Due to the heat of the sun, a huge volume of water evaporates from various water bodies during the day and rises into the air. As a consequence, a low-pressure area is formed. When air is heated, it becomes lighter and rises in the atmosphere. It blocks or slows down the escape of heat from the Earth into outer space during the night- time.Īns: The uneven heating of the Earth's surface causes winds. It avoids a sudden increase in the temperature during the daytime due to the sun. How Does the Atmosphere Act as a Blanket?Īns: The atmosphere keeps the temperature of the Earth constant. However, carbon dioxide makes up the majority of the atmosphere on Venus and Mars, which could range between 95 to 97 per cent.Ģ. This allows for the existence of life on Earth. The atmosphere of the Earth is composed of nitrogen, oxygen, a trace of carbon dioxide, water vapour, and other gases. How is Our Atmosphere Different from the Atmospheres on Venus and Mars?Īns: The composition of Earth's atmosphere differs from that of Venus and Mars.
