Sub Topic: Wind, breeze and storm. Wind:Moving air is called wind. Breeze: Slow and gentle moving wind is called breeze. Storm : Fast and strong moving wind is called storm.
What is moving air called?
Wind is moving air and is caused by differences in air pressure within our atmosphere. ... Air under high pressure moves toward areas of low pressure.
What is very fast moving air called?
When the air moves fast, It is called wind . Sometimes, the wind moves very fast along with heavy rains. ... Such a strong wind is called a storm.
What is fast moving wind?
Short bursts of high speed wind are termed gusts . Strong winds of intermediate duration (around one minute) are termed squalls. Long-duration winds have various names associated with their average strength, such as breeze, gale, storm, and hurricane.
What are the 4 types of wind?
Ans. The different types of winds on earth are planetary winds, trade winds, periodic winds, local winds, and westerlies . 2.
What causes air to move?
Air in the atmosphere moves around the world in a pattern called global atmospheric circulation. ... This pattern, called atmospheric circulation, is caused because the Sun heats the Earth more at the equator than at the poles . It’s also affected by the spin of the Earth. In the tropics, near the equator, warm air rises.
What is moving air Class 1 called?
Air is moving which is now called wind .
The atmosphere is open system which meant things effect of it.
What happens when air moves too fast?
A wing is shaped and tilted so the air moving over it moves faster than the air moving under it. As air speeds up, its pressure goes down. So the faster-moving air above exerts less pressure on the wing than the slower-moving air below. The result is an upward push on the wing— lift !
What is the most important reason for air movement?
The movement of air through Earth’s — or any planet’s — atmosphere is called wind, and the main cause of Earth’s winds is uneven heating by the sun . This uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.
What is strong wind called?
A very strong wind is called storm .
What is a very strong wind?
A very strong wind is called as storm .
What is it called when wind blows softly?
A gentle wind or when the wind blows slowly, it is called a breeze .
What are the 7 winds?
| Beaufort number Description Wind speed | 6 Strong breeze 10.8–13.8 m/s | 7 High wind, moderate gale, near gale 28–33 knots | 32–38 mph | 50–61 km/h |

Which wind direction is the strongest?
They are fed by polar easterlies and winds from the high-pressure horse latitudes, which sandwich them on either side. Westerlies are strongest in the winter, when pressure over the pole is low, and weakest in summer, when the polar high creates stronger polar easterlies.
What are the 3 major wind systems?
There are three prevailing wind belts associated with these cells: the trade winds, the prevailing westerlies, and the polar easterlies (Fig.
Is air always moving?
Air is constantly moving around the earth . This moving air is called wind. Winds are created when there are differences in air pressure from one area to another. ... This is what makes air move, creating the wind.
