It sounds like you're describing ocean currents! Specifically, this could refer to the warm and cold ocean currents that circulate in the Earth's oceans, playing a crucial role in regulating climate and weather patterns.
- Warm currents (like the Gulf Stream) typically travel from the equator towards the poles, redistributing heat.
- Cold currents (like the California Current) move from polar regions towards the equator, bringing cooler water.
These currents do indeed occur in different oceans and can start from various regions, including the equator and the poles. Would you like more information on specific ocean currents or their impacts on the climate?
