Lightning By Ashley Mildren

How Rain Formes Lightning comes from thunder clouds, known as cumulonimbus. These are created when hot moist air rises in to the atmosphere and condenses. Hot air rises when it is heated by the sun, carrying water vapour into the sky. As it rises, the hot air mixes with colder air, and the moisture condenses into water droplets. Clouds are created when these water droplets become visible. The droplets increase in size as the cloud grows and eventually becoming so heavy that they fall as rain. Thunder clouds are large, anvil-shaped masses that can stretch miles across at the base, and reach 40,000 feet or more in to the atmosphere.

Lightning happens when the negative charges (electrons) in the bottom of the cloud are attracted to the positive charges (protons) in the ground. Lightning happens when the negative charges (electrons) in the bottom of the cloud are attracted to the positive charges (protons) in the ground.

The accumulation of electric charges has to be great enough to overcome the insulating properties of air. When this happens, a stream of negative charges pours down towards a high point where positive charges have clustered due to the pull of the thunderhead.

The connection is made and the protons rush up to meet the electrons. It is at that point that we see lightning and hear thunder. A bolt of lightning heats the air along its path causing it to expand rapidly. Thunder is the sound caused by rapidly expanding air.
