Wind is the movement of air caused by the uneven heating of the Earth by the sun . ... Warm equatorial air rises higher into the atmosphere and migrates toward the poles. This is a low-pressure system. At the same time, cooler, denser air moves over Earth’s surface toward the Equator to replace the heated air.
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.
What is wind Short answer?
Wind refers to the air movement from high pressure to low-pressure areas. It can be broadly divided into Permanent, periodic and local winds. Complete answer: In simple terms, the wind is nothing but moving air . The air movement is always from high pressure to low-pressure areas.
How do you explain wind?
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. The greater the difference in pressure, the faster the air flows.
What is wind give an example?
A local wind is a flow of air that tends to happen in a predictable way in a particular, local area. ... Examples of local winds include sea breezes , which blow from the sea to the land and keep coastal temperatures more mild, and land breezes, which blow from the land toward the sea, usually at night.
What are the 4 types of local winds?
The main types of local winds are sea breezes and land breezes, Anabatic and katabatic winds, and Foehn winds .
What are the 4 types of winds?
The four major wind systems are the Polar and Tropical Easterlies, the Prevailing Westerlies and the Intertropical Convergence Zone . These are also wind belts. There are three other types of wind belts, also. They are called Trade Winds, Doldrums, and Horse Latitudes.
What is wind answer in one word?
noun. a current of air , sometimes of considerable force, moving generally horizontally from areas of high pressure to areas of low pressureSee also Beaufort scale Related adjective: aeolian. mainly poetic the direction from which a wind blows, usually a cardinal point of the compass.
What is called the wind class 7?
Wind. Wind. Moving air is called Wind. Since air is a mixture of gases, wind is the flow of gases on a large scale.
What is wind and its types?
Wind can be described as the movement of air from the high-pressure area to the low-pressure area. There are many types of wind such as permanent, seasonal and local winds . A wind is named after the direction from which it blows, e.g. the wind blowing from the west is called westerly.
What is the importance of wind?
Wind is an important element when it comes to current weather and predicting future forecasts . Wind transports moisture and temperature from one area to another, therefore weather conditions change with the shift of wind direction.
What causes wind to happen?
Wind is the movement of air caused by the uneven heating of the Earth by the sun . ... Warm equatorial air rises higher into the atmosphere and migrates toward the poles. This is a low-pressure system. At the same time, cooler, denser air moves over Earth’s surface toward the Equator to replace the heated air.
How is wind used today?
