WebThe wind is the result of uneven heating of the Earth's surface. But how do air masses cause both light and strong breezes? It is quite easy to understand how the wind is created. The atmosphere is comprised of four layers: troposphere, stratosphere, mesosphere, and thermosphere. They hover more than 100 kilometers above the crust of the Earth. WebThunderstorms form when warm, moist air rises into cold air. The warm air becomes cooler, which causes moisture, called water vapor, to form small water droplets — a process called condensation. The cooled air drops lower in the atmosphere, warms, and rises again. This circuit of rising and falling air is called a convection cell. how to shower for menWeb12 mrt. 2024 · Wind is air in motion. Wind forms when the sun heats one part of the atmosphere differently than another part. This causes expansion of warmer air, making less pressure where it is warm than where it is cooler.
