In what common hemisphere are asia, africa, australia, and antarctica located?

Eastern Hemisphere??

What sea can be found near the southern tip of Greenland?
Labrador Sea?

Both your answers are correct. :-)

Yes, Asia, Africa, Australia, and Antarctica are all located in the Eastern Hemisphere. To determine this, you can refer to a map or a globe. The Earth can be divided into two hemispheres, namely the Eastern Hemisphere and the Western Hemisphere, separated by the Prime Meridian. The Prime Meridian passes through Greenwich in London, England and serves as the reference point for measuring longitudes.

To find the sea near the southern tip of Greenland, you can consult a map or use an online mapping tool. The sea in question is actually the North Atlantic Ocean, not the Labrador Sea. The Labrador Sea is located further north, between Labrador (a region in eastern Canada) and Greenland. So, the correct answer is the North Atlantic Ocean.
