one half of the Earth
One of the two big halves of the Earth, such as the Northern Hemisphere or the Southern Hemisphere.
Vzorec užití:
the [Northern/Southern/Eastern/Western] Hemisphere
Častá chyba:
Learners sometimes write 'northern hemisphere' without capital letters. In English, we usually capitalize official names like 'Northern Hemisphere' and 'Southern Hemisphere'. Some learners also confuse 'hemisphere' with 'continent'; a hemisphere is half of the Earth, while a continent is a large landmass.

half of the globe (Emphasizes the Earth as a round object; slightly more formal or visual.)
