How do thunderstorms form short answer?
Thunderstorms form when warm, moist air rises into cold air. The warm air becomes cooler, which causes moisture, called water vapor, to form small water droplets – a process called condensation. The cooled air drops lower in the atmosphere, warms and rises again.
How are thunderstorms formed in steps?
Thunderstorms arise when layers of warm, moist air rise in a large, swift updraft to cooler regions of the atmosphere. There the moisture contained in the updraft condenses to form towering cumulonimbus clouds and, eventually, precipitation.
How do thunderstorm form for kids?
Thunderstorms happen when hot, moist air rises quickly to cooler parts of the atmosphere. There, the air cools, and clouds and rain form. Lightning, which is a form of electricity, develops inside the clouds. As the lightning heats the air, it causes it to expand.
How do you explain thunder to a child?
Because thunder is a sound, and sound is a slow poke. Lightning is so bright that you can see it for miles and miles, but thunder can’t always go that far. So, sometimes you see lightning and don’t even hear it, which means it’s pretty far away.
How does a thunderstorm develop Class 7?
Thunderstorms are due to the uneven heating of air around the earth. The earth’s surface is heated by the surface of the sun. Air above the earth’s surface is heated by conduction. As the temperature increases, strong and upward rising winds are produced.
What causes a thunderstorm?
The Short Answer: Unstable air forms when warm, moist air is near the ground and cold, dry air is above. Lift comes from differences in air density. It pushes unstable air upward, creating a tall thunderstorm cloud.
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.
Where do thunderstorms develop?
Thunderstorms can form and develop in any geographic location but most frequently within the mid-latitude, where warm, moist air from tropical latitudes collides with cooler air from polar latitudes. Thunderstorms are responsible for the development and formation of many severe weather phenomena.
What causes lightning Class 8?
Lightning is caused by the accumulation of charges in the cloy s. Some objects can be charged by rubbing with other objets. The electrical charge produced by rubbing is called static charge. There are two ]rinds of charges-positive charge and negative charge.
What causes lightning without thunder?
Thunder starts as a shockwave from the explosively expanding lightning channel when a large current causes rapid heating. However, it is possible that you might see lightning and not hear the thunder because it was too far away. Sometimes this is called “heat lightning” because it occurs most often in the summer.
How do you teach kids about thunder?
Have your child count the seconds between the flash of lightning and the sound of thunder during a thunderstorm. For every second, the storm is about one mile away. As the thunderstorm gets closer, the time between the flash and the sound gets closer together. As the storm moves away, the count will be higher.
Why is the 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.
What Colour is lightning kids?
The air around the lightning bolt determines the color of the lightning. Lightning over the water or during a rainstorm is generally red. Lightning occurring in low humidity is often white. Blue lightning typically occurs during some of the most powerful storms.
What are all of the requirements for a thunderstorm to form?
Moisture – torn form clouds and rain
What three conditions are required for a thunderstorm to form?
A significant increase of wind speed with height will tilt a storm’s updraft.
What conditions are needed to form a thunderstorm?
– Cold air. Below freezing temperatures in the clouds and near the ground are necessary to make snow and/or ice. – Lift. Something to raise the moist air to form the clouds and cause precipitation. – Moisture. To form clouds and precipitation. Air blowing across a body of water, such as a large lake or the ocean, is an excellent source of moisture.
How does a thunderstorm begin to form?
A combination of moisture,air,and lift is what causes a thunderstorm to happen.
