Parts of Florida received more than 12 lightning strikes per square kilometer per year, the most lightning activity in the United States . While most of lightning's energy produces thunder, hot air, light and radio waves, the small fraction remaining when the bolt strikes the ground is still five times hotter than the surface of the sun, many times the melting temperature of quartz.
