Which continents include locations that have “east longitude” in their address?

So the "east longitude" would correspond to the Eastern Hemisphere.

going from 0 Degrees Meridian at Greenwich eastwards, we have:

Europe,
Africa,
Asia
Australia

and parts of Oceania (more region than a continent)

Antarctica is also partially in the Wastern Hemisphere

America is almost entirely in the Western hemisphere with a small exception of some Islands in Alaska
