What natural phenomenon initiates the global wind cycle?

• The gravitational pull of the moon

• The rotation of the Earth

• The melting of polar ice caps

• The rise of hot air at the Equator

How do wind turbines generate electricity?

• By using water currents to turn a generator

• By burning fossil fuels to create steam

• By converting the kinetic energy of wind into electrical energy

• By using solar panels to capture sunlight

What is a significant advantage of wind turbines despite their high installation cost?

• They require no maintenance

• They produce energy only during the day

• They are cheap to operate

• They can be installed anywhere

Why might some areas be unsuitable for wind turbines?

• The wind is too strong

• The wind is too unpredictable

• The wind does not blow consistently

• The wind is too cold

What is a common criticism of wind turbines regarding their impact on the environment?

• They increase air pollution

• They consume a lot of water

• They are considered noisy and unattractive

• They deplete natural resources
