Does thunder mean lightning hit the ground?
Thunder is caused by the rapid expansion of the air surrounding the path of a lightning bolt. As lightning connects to the ground from the clouds, a second stroke of lightning will return from the ground to the clouds, following the same channel as the first strike.
Why does lightning strike the ground?
Since similar-charged objects repel each other and opposite-charged objects attract each other, negative charges begin to spread out near the base of the cloud. A cloud-to-ground lightning strike starts as a channel of negative charges called a stepped leader makes its path towards the ground.
What strikes the ground lightning or thunder?
Does lightning strike from the sky down, or the ground up? The answer is both. Cloud-to-ground (CG) lightning comes from the sky down, but the part you see comes from the ground up. A typical cloud-to-ground flash lowers a path of negative electricity (that we cannot see) towards the ground in a series of spurts.
Can lightning travel through the ground?
An indirect lightning strike can happen two different ways. The first way is through a ground current. These occur when lightning strikes an object or the ground and the electricity travels through the ground until it encounters another object. The second way is through a side flash.
Does lightning make noise when it hits the ground?
This rapid expansion and contraction creates the sound wave that we hear as thunder. Although a lightning discharge usually strikes just one spot on the ground, it travels many miles through the air. The loud boom that you sometimes hear is created by the main lightning channel as it reaches the ground.
How often does lightning strike the ground?
How many times per day does lightning strike the Earth? About 100 lightning bolts strike the Earth’s surface every second That’s about 8 million per day and 3 billion each year.
Why is there lightning but no rain?
Dry thunderstorm refers to thunder and lightning that occur without bringing rain to the ground. In fact, the thunder-bearing clouds do produce rain but the rain droplets have evaporated in the air before reaching the ground. The anvil cloud is so high that rain coming from it evaporates before reaching the ground.

What happens when lightning strikes ice?
In a thundercloud, millions of chunks of ice pushed by updrafts with speeds ranging from 10mph to 100mph, continually bump together, causing small ice crystals. These become positively electrically charged and float to the top of the cloud.
How often does lightning touch the ground?
About 100 lightning bolts strike the Earth’s surface every second That’s about 8 million per day and 3 billion each year.
What are facts about thunderstorms?
Thunderstorm Facts. A thunderstorm is basically a raging weather condition, which is accompanied by lightning and is characterized by an acoustic effect on the Earth’s atmosphere.

What are the effects of thunderstorms?
Effects of Thunderstorms. Thunderstorms have wide-ranging effects on human life, including electrocution, shock, and even worse, deaths. They normally have a significant effect on the weather over an expansive area, with energy generated at the rate of at least 10,000,000 kilowatt-hours on an average.
What are some interesting facts about lightning?
Interesting facts about lightning. Lightning is an amazing and breathtaking sight to witness. At the same time it is one of the most dangerous and unpredictable of all natural phenomena. Lightning is a powerful burst of electricity that happens very quickly during a thunderstorm. A bolt of lightning is 5 times hotter than the surface of the sun.
What are the safety precautions for a thunderstorm?
Safety precautions indoors Avoid water during a thunderstorm. Lightning can travel through plumbing. Avoid electronic equipment of all types. Lightning can travel through electrical systems and radio and television reception systems. Avoid corded phones. However, cordless or cellular phones are safe to use during a storm.
