What is thunder class 8?

Thunder is the sound made by a flash of lightning. As lightning passes through the air it heats the air quickly. This causes the air to expand rapidly and creates the sound wave we hear as thunder.

What is thunder short answer?

Thunder is the sound caused by lightning. Depending upon the distance from and nature of the lightning, it can range from a long, low rumble to a sudden, loud crack. The sudden increase in temperature and hence pressure caused by the lightning produces rapid expansion of the air in the path of a lightning bolt.

What is lightning class 8 science?

Lightning is a sudden electrostatic discharge that occurs typically during a thunderstorm. This discharge occurs between electrically charged regions of a cloud (called intra-cloud lightning or IC), between two clouds, or between a cloud and the ground.

What causes lightning Class 8?

Cause of lightning

During thunderstorm, when a charged cloud passes over an uncharged cloud, uncharged cloud acquires opposite charge by induction and the two clouds attract. When they combine with each other, they produce a large amount of heat, light and sound also known as lightning.

How are lightning and thunder caused Class 8?

Water droplets in the air act as a conductor of this charge. These charges flow to meet, thus producing strikes of lightning and thunder. For this phenomenon to occur, a sufficiently high electric potential between two regions and a high resistance medium must be present.

Lightning and thunder

How can you save yourself from lightning Class 8?

What are charges Class 8?

Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. Positive and negative electric charges are the two types of charges commonly carried by charge carriers, protons and electrons. Energy is created by the movement of charges.

What are the dangers of lightning Class 8?

What are the 3 types of lightning?

There are three common types of lightning: cloud to ground, cloud to cloud and cloud to air. Cloud to ground lightning is the most dangerous. The ground is mainly consisted of positively charged particles while the bottom of violent storm clouds have negative charged particles.

What you will do on being struck by lightning Class 8?

A person struck by lightning should be made to lie in a place where there is good air circulation. In order to prevent blood clotting keep the body warm by massaging. Give artificial respiration and press strongly on the chest to maintain heartbeat and the person must be taken to a hospital immediately.

What causes thunder?

Thunder is caused by the rapid expansion of the air surrounding the path of a lightning bolt.

What is thunderstorm class 7?

The rising temperatures produce strong upward rising winds. These winds carry water droplets upwards, where they freeze, and fall down again. The swift movement of the falling water droplets along with the rising air create lightning and sound. It is this event that we call a thunderstorm.

What is a thunder in science?

Thunder is the sound made by a flash of lightning. As lightning passes through the air it heats the air quickly. This causes the air to expand rapidly and creates the sound wave we hear as thunder. Normally, you can hear thunder about 10 miles from a lightning strike.

Why is thunder so loud?

Why is thunder so loud? It's because the amount of electrical energy that flows from the cloud to the ground is so enormous: it's like a very big waterfall of electricity. The louder the sound that you hear, the closer you are to the lightning. Light travels through air much faster than sound.

Is thunder a fear?

Astraphobia is the fear of thunder and lightning. It typically affects children, but many adults still deal with a fear of thunderstorms. Astraphobia is one of the most common specific phobias. Treatment such as talk therapy or medication can help you manage anxiety symptoms and live a higher quality of life.

How do you explain thunder to a 5 year old?

The lightning flash heats the air around it so quickly that the air expands very fast. When you heat something, it gets bigger – it expands. The air around the lightning flash expands so fast that it makes a shock wave in the air. That shock wave is the thunder that you hear.

What is the rarest lightning?

ball lightning, also called globe lightning, a rare aerial phenomenon in the form of a luminous sphere that is generally several centimetres in diameter.

What is the strongest lightning called?

Positive lightning is what you need to watch out for. Not only does it tend to come after the storm seems to have passed, but it also produces much more energy. Whereas negative lightning produces 300 million volts and 30,000 amps, positive lightning can produce nearly a billion volts and 300,000 amps.

What are the 7 types of lightning?

Is the car safe during thunderstorm Class 8?

A car or a bus is safe during lightning because the lightning will travel around the surface of the vehicle and then go to ground. The metallic frame of the car, being a good conductor, would direct the current around the objects and discharge it safely to the ground while shielding the objects inside the car.

What is the safest place during lightning Class 8?

A house or a building or a car with closed windows and doors is a safe place to hide during a lightning.

Which places are not safe during a thunderstorm Class 8?

Stay away from open spaces such as golf courses, parks, playgrounds, ponds, lakes, swimming pools, and beaches. Seek shelter immediately. Don't stay near tall structures. Stay away from tall structures, such as telephone poles and trees; lightning tends to strike the tallest object around.

What is electricity class 10?

The flow of charges in a conductor is defined as electricity. Charges are transferred from one end of the terminal to the other. It usually progresses from a positive to a negative terminal. The electrons travel freely within the body since the nucleus holds them loosely.

What is electric force class 8?

The force exerted by a charged body on another charged or uncharged body by virtue of its charge is known as electrostatic force.

What is electric current class 8?

Electric Current is the rate of flow of electrons in a conductor. The SI Unit of electric current is the Ampere. Electrons are minute particles that exist within the molecular structure of a substance.
