What are global winds responsible for?

Global winds play a crucial role in transferring heat between the tropics and polar regions. This process helps to regulate the Earth's climate by distributing thermal energy, which ultimately influences weather patterns and temperatures across different regions. The movement of air masses driven by global winds facilitates this heat exchange, resulting in a moderating effect on both tropical and polar climates.

The other options do not accurately represent the role of global winds. Creating lightning storms is primarily associated with convective processes in localized weather systems rather than the broad patterns of global winds. While global winds can influence ocean currents, they do not sustain them directly; ocean currents are driven by a combination of wind, Earth's rotation, and differences in water density. Lastly, initiating seismic activity is related to geological processes and tectonic plate movements rather than atmospheric phenomena like global winds.
