2. Thunderstorm

As the warm air rises, it takes its moisture with it. As this air rises, it will eventually meet colder air higher up in the atmosphere. When this happens, the moisture in the air will condense and form water droplets, forming clouds. With more and more water being taken up into the clouds, the clouds become increasingly dense, blocking out the sun if it is daytime.

These droplets will also become frozen and will rub and bump into each other, causing friction. This friction generates an electrical charge and this charge will occasionally be released in what we know as lightning. When the lightning suddenly heats the air, it causes that air to expand, causing a shockwave that we hear as thunder.
