MCQ Wind

The document contains multiple choice questions about wind energy. It asks about the definition of wind, how wind energy can be harnessed and measured, factors that influence wind patterns like uneven heating of the Earth's surface, and favorable locations for wind energy generation such as deserts and offshore sites. The main source of wind is the uneven heating of the Earth's surface by the sun, which causes convection currents in the atmosphere. Wind energy can be captured as kinetic or mechanical energy using wind turbines.
