Lightning and thunder occurs at almost the same time because lightning is produced by cold and warm masses of air that clashes against each other. This causes friction resulting in sparks of electrical energy that is famous as lightning shooting right down to the floor. Besides lightning, the clash of cold and warm fronts of air produces a loud booming sound which is famous as thunder.
Lightning and thunder take place at the same time however lightning is seen first before hearing the thunder. The scientific reason is the mild travels quicker than the speed of sound through the atmosphere. The longer gap between lightning and thunder means that the thunderstorm is additional away.

The 2nd factor behind the rumble of thunder is the presence of mountains and clouds around the area. The sound waves start off from the clouds, floor and other nearby items which are much equivalent to the way a human voice echoes in an oversized auditorium. This is the reason the sound of thunder might become louder than getting reduce a bit.
Lightning can take place without thunder however thunder cannot take place without lightning. The reason is likewise that a person is awfully far away to pay attention the thunder. The sound waves scatter however the lightning continues to be visible in the sky.
When the air explodes as a result whenever lightning heats the air, each part of the lightning bolt creates compression waves so one can reach at different times. The sound wave that travels a longer distance is softer and arrives later than a sound wave that was created by a part of lightning bolt that was closer.
When air explodes interior a thunder cloud when lightning heats it up, a thunder is produced. A lightning strike can rapidly heat up the air between the temperatures of 15000 to 60000 Fahrenheit; here is hotter than the surface of the sun. Air expands violently and contracts when heated rapidly, this causes the air to explode with a booming sound. The air which rushes out sets up a sound wave of vibrating air which is famous as thunder.
