Why is Air Important For Us?
Air is crucial for life on Earth because it provides the oxygen essential for respiration, enabling humans, animals, and plants to survive. Additionally, air regulates the Earth’s temperature by distributing heat around the globe through wind currents and absorbing sunlight. It also plays a vital role in the water cycle, facilitating the movement of moisture and precipitation.
Moreover, air quality affects human health, with pollutants and contaminants in the air posing risks to respiratory systems and overall well-being. Overall, air is essential for sustaining life and maintaining ecological balance on our planet. The various important roles of air are:
- Air for Breathing
- Air for Photosynthesis
- Air for Combustion
- Air for weather and climate
- Air for Regulating Temperature
- Air for Sound Transmission
Without air, life as we know it would not be possible on Earth. It is a vital resource that sustains countless organisms, facilitates various natural and human-made processes, and helps maintain the delicate balance of our planet’s ecosystems.
Air for Breathing and Combustion
Air is one of the elements that sustains life on Earth. Air serves two crucial functions – sustaining life through respiration and fueling combustion processes. The air around us makes up the Earth’s atmosphere, which extends about 11 kilometres high. As we get closer to the ground, the air becomes thicker because of gravity.
This air has the right mix of gases and pressure to support life. High in the atmosphere, the ozone layer acts like a shield which protects us from harmful rays from space. In this article, we will read about how air is used in respiration and combustion.
