Europe, Antarctica and Africa: both Western and Eastern.
South America, Asia and Africa: both Southern and Northern.
Only includes contrasting hemispheres.
Valley glaciers typically flow down valleys and do not spread out over large islands or continents. They are confined to the topography of the land and move under the influence of gravity. Ice sheets, on the other hand, can cover large landmasses like islands and continents.
The earliest humans are believed to have migrated out of Africa. It is thought that modern humans originated in Africa and then spread to other continents over time.
The two processes that contribute to the growth of continents over time are accretion, where new landmasses are added to existing continents through tectonic activity, and magmatism, where volcanic activity generates new crust that can add to the size of continents. These processes can lead to the gradual expansion of continents over geological timescales.
The position of continents has changed over time due to plate tectonics. Continents have moved through processes like seafloor spreading, where new crust forms at mid-ocean ridges, and subduction, where crust is pulled back into the Earthโs mantle. Over millions of years, these movements have created the current positions of the continents on Earthโs surface.
Continents are constantly moving due to tectonic plate activity, a process that happens over millions of years. It is difficult to predict when or if continents will unite again in the future.
-- Australia is completely in the eastern and southern Hemispheres. -- Asia includes territory in the eastern, northern, and southern Hemispheres. -- Antarctica lies in the eastern, western, and southern Hemispheres. -- Africa includes territory in all of them: Eastern, western, northern, and southern. -- North America is in the western and northern Hemispheres, plus ... don't make me have to prove this ... North America also lops over into the eastern Hemisphere, and here I'm not talking about politically.
They were spread apart over a period of time when the earth's crust was moving.
it is very complicated..
Which country? Buddhism is over 2,500 years old and has spread to all continents over that time.
Antarctica is in both the eastern AND western hemispheres, and in the southern, of course.Another AnswerAs to 'why', the answer is simply that the lines drawn by humans over the earth separating hemispheres happen to bisect this continent.
Since the Earth rotates all the way around every 24 hours, the moon is over both the eastern and western hemispheres for roughly 1/2 of every day. It's also over both the northern and southern hemispheres for roughly 1/2 of every four weeks.
The Pangea puzzle is the theory of the beginning of the continents. It's how the Earth started out. Well it is the theory of how the continents came to be. The legend has it that way back in time, there weren't any continents. There was just one large landmass. Until it started to spread apart. That is when it was no longer just one piece. But there were 7 different landmasses. Over hundreds of thousands of years, those landmasses spread apart into what we know now as our 7 continents.
The are all over in all continents but Antarctica
There have been many forms of humans on the planet over the last at least 400,000 years. The human race that now lives on the earth (homo sapiens) developed some 200,000 years ago.It took quite a while before they had spread over all the continents on the planet. They started spreading over the continents some 70,000 years ago and they finished spreading to all the continents some 15,000 years ago.
The Islamic Empire is in three continents Asia, Africa, and Europe. Islam is spread all over the world (as Christianity) but with different percentage of Muslims to each country total population.
Africa was formed when the supercontinent Pangia started to spread apart over the course of millions of years, thus creating all the continents including Africa
Africa is one continent. It has over 50 countries. See the related question below. Africa has two neighbouring continents, Europe and Asia, both very close by.
