Air, which all animals and plants need to survive, is made up of a mixture of gases. When air theoretically moves it  presses against everything in its path such as rustling leaves and lifting kites high above into the atmosphere. Around the earth there is a blanket of air that is roughly around 640KM deep . Air is light but this blanket of air around the earth presses down on everything, including you and I,  with a force equal to 10.4 M of water, This is the equivalent of begin down at 34Ft under the sea. We don’t usually notice the weight of air pressing down on us as it presses equally from all sides as our body. Liquid presses out equally on all sides against the pressure of the air. The pressure around the earth is lower at high altitudes. For example, an airplane at the height of 16,000 M [ 52,000 FT ] above the Earth’s crust the air pressure is 1 10th that of pressure on the earth’s surface.

We can use air to our advantage in life For example, a parachute increases air resistance by collecting air to put  under in its canopy. This is so that the parachutist falls slowly to the ground ;they do not end up hurting themselves as they fall from the Sky at a high altitude.

 

Another use os to use an Air Conditioning Gloucester like ACCEC to come and fit a system in your home that provides cooling air to reduce the effects of a heatwave.
