WHAT CAUSES WIND?

Earth’s atmosphere is structured into five main layers. From the closest to farthest from Earth’s surface, these are the troposphere, stratosphere, mesosphere, thermosphere and exosphere. The air gets thinner as the distance from the planet’s surface increases, but each of these atmospheric layers displays turbulence. Air particles are constantly churned both vertically and horizontally; this turbulence is also known as wind. The wind we experience when we venture outside is in the troposphere, and it can vary extremely in temperature and strength. But what causes these tiny particles to move so ferociously, and in unison, that the feeling of wind hitting the skin can be as strong as a slap in the face?

Air changes position in the atmosphere as its pressure alters. When its particles
