Final answer:
The correct option is c) It transports warm and cold water across the globe. The global ocean conveyor belt, influenced by temperature and salinity, has a significant impact on world climate by affecting temperature and precipitation patterns, not solely dependent on wind patterns.
Step-by-step explanation:
The correct statement about the global ocean conveyor belt is: c) It transports warm and cold water across the globe.
The global ocean conveyor belt, also known as thermohaline circulation, is a continuous system of deep-ocean circulation driven by temperature and salinity. The movement of warm and cold water helps to distribute heat around the globe, which is essential for maintaining climate patterns. While wind patterns do influence surface currents, the conveyor belt is not driven solely by wind but also by water density differences created by varying temperatures and salinity levels. The conveyor belt has a significant impact on climate because it affects temperature and precipitation patterns worldwide. Although the water cycle is important for the Earth's overall climate system, the conveyor belt itself is not responsible for the water cycle. Instead, the Sun's energy drives the water cycle through processes like evaporation and precipitation.
