North America, Europe, South America, and Africa.
Northern, Southern, Eastern and Western.
Some countries that are both in the eastern and western hemispheres include Russia, United States, Brazil, and Australia.
The Equator is the most important imaginary line that divides the Earth into the Eastern and Western Hemispheres.
Nothing, no half of the world includes both Asia and Antartica. Antartica is located exclusively in the Southern Hemisphere as well as partially in the Eastern and Western Hemisphere. Asia which is the largest and most populated continent on Earth is primarily located in the Northern and Eastern Hemispheres but also extends into the Western and Southern Hemispheres. It’s the only continent located in all 4 hemispheres of the Earth.
Beringia or the Bering Land Bridge
There are seven continents and four hemispheres. Here are the locations (this may all make more sense if you see it on a map): Africa stretches through both the Northern and Southern hemispheres, as well as the Eastern and Western hemispheres. Antarctica is in the South Pole, and within the Southern Hemisphere. It extends through the Eastern and Western hemispheres. Asia, like Africa, extends through all hemispheres. It is mostly within the Northern and Eastern hemispheres, but part of it (Indonesia, which is considered a part of the Asian continent) goes into the Southern hemisphere, while another part, Russia, extends through the Eastern hemisphere, and onward to the Western hemisphere. Australia is within the Southern and Eastern hemispheres only. Europe is mostly situated within the Eastern hemisphere, but entirely within the Northern hemisphere: the United Kingdom, France and Spain stretch into both the Eastern and Western hemispheres, while Portugal and Ireland are completely within the Western hemisphere. North America is situated entirely within the Northern hemisphere, and it also within the Western hemisphere. South America-- the equator crosses through it, so it is in both the Northern and Southern hemispheres, and entirely within the Western hemisphere. I enclose a link to some maps of the continents and their locations.
Greece is in the northern and eastern hemispheres
I live in the US, and the majority lives in the Northern and Western Hemispheres, which would be the the majority of the continental US as well as the Hawaiian Islands, Puerto Rico, and the US Virgin Islands. But the Aleutian Islands (of Alaska) cross the International Dateline making them part of the Eastern Hemisphere, in which case you would live in the Northern and Eastern Hemispheres. Other US territories are in the Pacific, and of which, American Samoa is in the Southern and Western Hemispheres. (Other inhabited territories include the Northern Mariana Islands and Guam, which are in the Northern and Eastern Hemispheres, like part of the Aleutian Islands) If you lived in the UK, you would most likely be in the Northern and Western Hemispheres, unless you lived on the east of the prime meridian, in which case you would be in the Northern and Eastern Hemispheres. If you lived in Canada, you would be in the Northern and Western Hemispheres. If you lived in Australia, you would be in the Southern and Eastern Hemispheres. If you lived in New Zealand, you would be in the Southern and Eastern Hemispheres, or the Southern and Western Hemispheres (Cook Islands, Niue, etc.)
the equator, the imaginary line that divides the western and eastern hemispheres is called the prime meridian
Northern Hemisphere, Southern Hemisphere, Western Hemisphere, and the Eastern Hemisphere.
the eastern highlands are located in brazil because as the name suggests it is found in the western part of the continent and so it is found in brazil.
