Question

1. what is pressure? 2. how wind is formed?

Explanation:

Wind is formed due to differences in air pressure. The sun heats the Earth's surface unevenly, causing air to warm and rise in some areas and cool and sink in others. This creates pressure differences, and air moves from high - pressure areas to low - pressure areas, resulting in wind.

Answer:

Wind is formed from differences in air pressure caused by uneven heating of the Earth's surface by the sun.
