Continents are the large land masses that sit atop the Earth's crust, on tectonic plates having lighter material than the ocean plates.
There are seven continents. In order of decreasing size they are :
- North America
- South America
- Australia (sometimes erroneously referred to as Oceania)
The masses of Europe and Asia are linked, and still just barely separated from Africa. North and South America are joined by a narrow isthmus, Panama. The land areas of Earth might be considered large islands in the global ocean. The 7 continents are: North America, South America, Europe, Asia, Africa, Australia and Antarctica. [Sometimes Oceania]
The equator passes South America, Africa, AND Asia
Since the Earth is a sphere ... shaped like a ball ... you can start out from the Prime Meridian,
go either east or west, and arrive on any continent you want.
If it's North America or South America you're headed for, your trip is shorter if you go west.
If it's Asia or Australia you're headed for, the eastbound trip is the shorter one.
For the rest ... Europe, Africa, and Antarctica ... the Prime Meridian crosses them, so
you wouldn't say that either direction is closer.
