Question

what is wind ? what is wind ?​

Answer 1

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.

Answer 2

$\red{\bold{\underline{\underline{Answer}}}}$

Wind is the horizontal motion of the air past a given point.

Winds begin with differences in air pressures. When air pressure is higher at one place than another, it sets up a force. This force pushes from the high pressure towards the lower pressure. The greater the difference in pressures, the stronger the force. It’s important to note that there’s no set number that divides high and low pressure.

Wind speed is determined by air pressure. Besides force, the distance between the area of high pressure and the area of low pressure also determines how fast the moving air accelerates.

Meteorologists refer to the force that starts the wind flowing as the “pressure gradient force.” The higher the pressure gradient force, the faster the wind speed.
