Hint: A storm is a distubred state in the environment that involves strong winds or heavy precipitation or both. Storms are capable of causing a lot of damage and are formed due to pressure differences in the environment.
Complete answer:
Storms happen when low pressure is developed in a surrounding of high pressure. As land gets heated, the air above it rises and it creates a low pressure area. This low pressure area attracts air from surrounding areas. This leads to storms like thunderstorms and cyclones.
In hot, humid tropical areas, rising temperatures lead to strong upwards winds. These upwards winds carry water droplets with them which freeze and fall down again on earth. The upward movement of air as well and falling down of rain create lightning and sound.
When water vapour changes intro raindrops, heat is released in the atmosphere which warms the air. This leads to rising of air again and creating a drop in pressure. More air is pulled to the low pressure zone and this leads to a chain of events that lead to the formation of a very low pressure system with high speed winds revolving around it. This situation is called a cyclone.
Note: Sometimes, small localized areas of low pressure are formed due to hot air rising off. This localised area of low pressure leads to small disturbances like dust devils and whirlwinds.
