What is a wind how do the winds get their named NCERT class 7
Answers
Answer:
The pressure exerted by atmospheric gases on the surface of the earth is called air pressure. ... The low pressure zone created by ascending air is filled by cooler and heavier air, which flows in from the surroundings. This causes the wind to blow.
Answer:
Wind is moving air. ... Oxygen and nitrogen make up most of Earth's air molecules. As air heats up and cools down, it also exerts air pressure–which is like the weight of air–and a downward force.
A wind is often named in accordance to the direction from where it blows. As an example, wind processing from west to east may be an air current. The prime reason behind Earth's wind movement is alternative energy. Once daylight strikes Earth's surface, it heats the surface through heat induction.
How does wind get its name?
the wind is always named according to the direction from which it blows. ... This flow of air is wind. The difference in air pressure between two adjacent air masses over a horizontal distance is called the pressure gradient force. The greater the difference in pressure, the greater the force and the stronger the wind.
What are the 4 types of winds?
The Four Major Wind Systems and Wind Belts: 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.
