which current travels all the way around the world?

The Southern Ocean current around Antarctica goes all the way around.

why isnt there a similar current in the northern polar region?

There is no land mass under the Arctic ocean for it to circle around but Europe and Asia and North America stick way up there in the way.

thank u Damon

The current that travels all the way around the world is known as the Global Conveyor Belt, also called the Thermohaline Circulation. It is a system of deep ocean currents driven by temperature and salinity differences. While the term "current" is often used to refer to surface currents that move in specific directions, the Global Conveyor Belt is different because it primarily operates in the deep ocean and is driven by density.

To find more information about the Global Conveyor Belt, you can follow these steps:

1. Use a search engine: Open a web browser and go to your preferred search engine like Google, Bing, or Yahoo.

2. Enter the relevant keywords: Type in "Global Conveyor Belt" or "Thermohaline Circulation" in the search bar.

3. Review the search results: Look for reputable sources such as scientific publications, educational institutions, or government websites. These sources usually provide reliable and accurate information.

4. Click on relevant links: Explore the search results and click on links that seem credible and informative. Government websites like NOAA (National Oceanic and Atmospheric Administration) or educational institutions like universities often have reliable information about such topics.

5. Read and cross-reference information: Once you find a trustworthy source, read through the article or web page to gather information about the Global Conveyor Belt. Be sure to cross-reference multiple sources to ensure accuracy.

By following these steps, you should be able to find in-depth information about the Global Conveyor Belt and its role in circulating water around the world's oceans.
