Final answer:
The two continents that are located primarily in the northern and eastern hemispheres are Asia and Europe. Asia is the most extensive continent and primarily situated in the northern hemisphere. Europe is located north of the equator and largely in the eastern hemisphere.
Step-by-step explanation:
The two continents that are located mostly in the northern and eastern hemispheres are Asia and Europe.
The northern hemisphere refers to the half of the planet that is north of the equator, while the eastern hemisphere is the half of the earth located east of the prime meridian, which runs through Greenwich, London, and to the west of the antimeridian.
Asia is the largest continent and extends from the eastern hemisphere into a small part of the western hemisphere. It's mostly located in the northern hemisphere, with only some islands near the equator stretching into the southern hemisphere.
Europe is located entirely to the north of the equator and mostly in the eastern hemisphere, except for parts of Iceland and a few of its westernmost countries like Portugal and parts of the UK.
