What is the main source of energy that drives the global climate system?

  1. Wind

  2. Water

  3. Solar

  4. Tides

The correct answer is: Solar

The main source of energy that drives the global climate system is Solar. Solar energy from the sun is the primary driver of Earth's climate, as it heats the atmosphere and surface of the planet, leads to evaporation of water which forms clouds, and sets air and ocean currents in motion. Wind, water, and tides may contribute to small-scale weather patterns, but they do not have the same widespread impact on the global climate system like solar radiation does.
