#ONE CLICK DISTANCE CRACK#

Remember, if you can hear thunder, chances are that you're within striking distance of the storm.

Keep in mind that you should be in a safe place while counting. Because distance measurements require two clicks, you can still identify atoms with one click while measuring distances. If you count the number of seconds between the flash of lightning and the sound of thunder, and then divide by 5, you'll get the distance in miles to the lightning: 5 seconds = 1 mile, 15 seconds = 3 miles, 0 seconds = very close. Since you see lightning immediately and it takes the sound of thunder about 5 seconds to travel a mile, you can calculate the distance between you and the lightning. The loud boom that you sometimes hear is created by the main lightning channel as it reaches the ground. If the thunder sounds more like a rumble, the lightning was at least several miles away.

Typically, a sharp crack or click will indicate that the lightning channel passed nearby. As you continue to listen, you'll hear the sound created from the portions of the channel farther and farther away. When you listen to thunder, you'll first hear the thunder created by that portion of the lightning channel that is nearest you. This rapid expansion and contraction creates the sound wave that we hear as thunder.ДЄlthough a lightning discharge usually strikes just one spot on the ground, it travels many miles through the air. Immediately after the flash, the air cools and contracts quickly. The temperature of the air in the lightning channel may reach as high as 50,000 degrees Fahrenheit, 5 times hotter than the surface of the sun. The lightning discharge heats the air rapidly and causes it to expand. Thunder is created when lightning passes through the air. The sound of thunder should serve as a warning to anyone outside that they are within striking distance of the storm and need to get to a safe place immediately! Thunder is the sound caused by a nearby flash of lightning and can be heard for a distance of only about 10 miles from the lightning strike.
