Where are wind turbines placed?

• On land, near villages and towns

• On land and off shore

• Only on plains

• In windy areas

Winds are generated by

• the movement of clouds

• air moving from low to high pressure areas

• heat absorbed and then released by the Earth

• air moving from high to low pressure areas
