I thought I'd better look on the Internet to see what else I'd forgotten.
This is from one website:

Today, we have seven continents on planet Earth surrounded by 5 oceans. Each of the seven continental land masses is diverse and distinctly unique with their own plants, animals, deserts, mountains, rivers, lakes, cultures, and weather. A continent is larger than an island and is usually made up of multiple countries and span millions of square miles. The 7 continents of the world are North America, South America, Antarctica, Europe, Asia, Africa and Australia. Some consider the North and South American continent to be just one landmass referred to as the “American Continent.” Europe and Asia continent are also combined at times and referred to as “Eurasia.”

It seems there is no assent on this subject!
