What causes of lightning?
Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. This heat causes surrounding air to rapidly expand and vibrate, which creates the pealing thunder we hear a short time after seeing a lightning flash.
What causes lightning and thunder quizlet?
AIR is NOT a good conductor of electricity (electricity does not flow easily through it). Thunder is created when the lightning bolt HEATS the air to 54,000F. Such intense heats VIOLENTLY EXPANDS the air and creates a SOUND WAVE that we hear as thunder.
What causes lightning short answer?
Lightning happens when the negative charges (electrons) in the bottom of the cloud are attracted to the positive charges (protons) in the ground.
What causes lightning and thunder Newsela?
The negative charges in the cloud then reach out toward the positive charges on the ground. This creates a burst of electricity, or a lightning bolt. Lightning makes the air very hot for a moment, and this quick change causes the air molecules to vibrate, creating the sound of thunder.
What is the main cause of thunder?
Thunder is caused by the rapid expansion of the air surrounding the path of a lightning bolt. From the clouds to a nearby tree or roof, a lightning bolt takes only a few thousandths of a second to split through the air. The loud thunder that follows the lightning bolt is commonly said to come from the bolt itself.
What is the relationship between thunder and lightning quizlet?
What is the relationship between lightning and thunder? Lightning is an electric discharge that forms between clouds or between a cloud and the ground. The air around the lightning bolt expands rapidly to produce sound waves that we call thunder.
What is called lightning?
A discharge between cloud and ground initiated by an upward-moving leader originating from an object on the ground. Ground-to-Cloud lightning strikes – sometimes called upward-moving lightning – are common on tall towers and skyscrapers. GC lightning can also be either positive or negative in polarity.
What causes lightning and thunder answer key?
When the lightning flashes, the air around it becomes unbelievably hot—five times hotter than the surface of the sun! The heated air expands into the cooler air around it, causing the shockwave that we call thunder. In addition, both light and sound travel through the air in waves.
What causes lightning to happen in a cloud?
This is like a static electricity sparks you see, but much bigger. Most lightning happens inside a cloud, but sometimes it happens between the cloud and the ground. A build up of positive charge builds up on the ground beneath the cloud, attracted to the negative charge in the bottom of the cloud.
Why does lightning strike when the ground is hot?
Lightning strikes! When the ground is hot, it heats the air above it. This warm air rises. As the air rises, water vapour cools and forms a cloud. When air continues to rise, the cloud gets bigger and bigger. In the tops of the clouds, temperature is below freezing and the water vapour turns into ice. Now, the cloud becomes a thundercloud.
Where does most of the Lightning in the world occur?
Lightning strikes! When the positive and negative charges grow large enough, a giant spark – lightning – occurs between the two charges within the cloud. This is like a static electricity sparks you see, but much bigger. Most lightning happens inside a cloud, but sometimes it happens between the cloud and the ground. A build up…
When is Lightning is made the same thing happens?
When lightning is made the same thing happens, but on a much bigger scale. Below, we have listed points sequentially on how or why lightning occurs. Lightning can be explained in terms of charges produced due to rubbing. During a thunderstorm, the air currents move upwards and the water droplets move downwards.
