Topography and the Earth: the Land

The video explains that over 70% of the Earth is covered by water, with the rest being land. It describes how small land pieces are islands, while larger ones are continents. There are seven major continents: North America, South America, Asia, Europe, Africa, Australia, and Antarctica. Antarctica and Australia are isolated, while North and South America are connected by Central America. Europe and Asia form a single landmass called Eurasia.
