What continent lies completely north of the equator and east of the prime meridian

The correct answer is - Asia.

Asia is the continent that lies completely east f the prime meridian, and almost totally north of the equator. While it is not completely true that Asia is completely north of the equator, as very little portion of its southeasternmost part is south of the equator, still it is only about 1% of the continent, so we can say that Asia is a continent of the Northern Hemisphere.

Asia is the largest continent on the planet, even without Europe which is basically part of it, but it is a division between the two that happened on political, cultural, ethnic basis. It is a continent that also has the most population in the world. The climate and geography are changing from place to place and pretty much all types of them can be found on this continent. It is also the continent that has given birth to the earliest civilizations, as well as the religions with the most followers in the world.
