«LIGHTNINGS AND ALL ABOUT THEM»
Слайд 3INTRODUCTION
Since childhood, I have loved rainy weather, especially thunderstorms. It's nice to
sit on the balcony with a cup of hot tea and listen to the thunder and rain. This led me to become interested in the subject of lightning. What is it? How does this happen? How dangerous is it? How do I calculate where lightning struck?
So I want to tell you this. Enjoy your viewing!
Слайд 4WHAT IS LIGHTNING?
Lightning is an electrical discharge of 10-20 thousand Amperes with
a potential difference of up to a billion Volts that occurs between the earth's surface and rain clouds or only between clouds during a thunderstorm.
Слайд 5Lightning occurs in a highly electrified rain cloud, between a cloud and
the ground or between neighboring clouds. The cause of electrification is the force of attraction, which occurs due to the friction of condensed droplets or ice, from which a thundercloud is formed.
Слайд 6The lightning voltage is very huge and this energy is enough to
make a 100-watt bulb Shine continuously for 90 days. On average, one thunderstorm discharge carries up to 20,000 megawatts, while the temperature reaches 10,000 Kelvin, which is 5 times more than on the surface of the Sun.
Слайд 7TYPES OF LIGHTNING
linear (cloud-to-ground, ground-to-cloud, cloud-to-cloud)
horizontal or flat
ribbon
bead
stormy
volumetric
ball
volcanic
Слайд 8THE CALCULATION OF THE DISTANCE FROM THE LIGHT
By counting the number of
seconds after a lightning flash and multiplying it by 340, we can calculate the distance from lightning to the thunder
Слайд 9CONCLUSION
Now you know how and why lightning appears. I want to say
that this phenomenon is dangerous for all living things around us, including ourselves. During a thunderstorm, you can not be in the water, stand in the middle of a field and hide under a single tree.
