What is a
Continent?
Though there are many definitions of
the term “continent,” it is generally used to identify large distinct land
masses that make up planet Earth’s surface. What we know as land are actually
the areas which happen to be at a high enough elevation to not be flooded by
the lakes, rivers, and oceans of the world which surround them. The continents
shapes and boundaries are ever-changing as the water surrounding them defines
the land that makes up the continent. It is important to remember the five oceans of the world, as the continents make up just 1/3rd
of Earth’s surface.
What are the 7 Continents of the World?
Today, we have
seven continents on planet Earth surrounded by five oceans. Each of the seven continental land
masses is diverse and distinctly unique with their own plants, animals, deserts, mountains, rivers, lakes, cultures, and weather. A continent is
larger than an island and is usually made up of multiple countries and span
millions of square miles. The 7 continents of the
world are North America, South America, Antarctica, Europe, Asia, Africa and
Australia.
How Many
Continents Are There?
Some consider
the North and South American continent to be just one landmass referred to as
the “American Continent.” Europe and Asia continent are also combined at times
and referred to as “Eurasia.” The continent of Australia is often
confused with the country of Australia. The Australian Continent includes
Australia (country), Tasmania, New Guinea and others. This region is also
referred to as “Oceania,” which includes the previously listed countries as
well as New Zealand, Micronesian, and Polynesian islands. Oceania is generally
not considered a continent as it does not make up “a single continuous
landmass.”

5 Continents: Depending on when you went
through school and the country you were educated, you may have learned that
there were just 5 continents. Africa, America, Asia, Australia, and Europe.
Interestingly, this is why we have five rings to symbolize the Olympic
Games
·
6 Continents: In certain countries it is
common for students to learn about just 6 continents. America, Antarctica,
Asia, Africa, Australia (Oceania), and Europe. There are some geography experts
that acknowledge just 6 continents where the continent of Asia and Europe are
combined into a new continent called “Eurasia” as these two continents are one
single land mass.
·
7 Continents: The most commonly accepted number
of continents is 7. North America, South America, Africa, Antarctica, Australia
(Oceania), Europe, and Asia.
Below you will find a comprehensive 7
continents list exploring each of the continents with a summary. Under each
continent you can follow the link below it to learn more!
7 Continents List
Africa
Land Area of Africa: 11,670,000 (mi²) / 28,489,869 (km²)
Population of Africa: 1,119,307,147 (2016)
Largest City in Africa: Lagos, Nigeria (15,118,780 (2014))

While Africa is first alphabetically, it is
second in both population and size among the Earth’s seven continents. Over 1
billion people can call Africa home. The people of Africa are spread across 54
different countries in Africa. This continent is home to 15% of the world’s
population and the continent makes up 20% of the total land area on planet
earth. The equator passes through the center of the continent which provides
for largely warm and/or tropical climates. The northern and the southern
portion of Africa have more temperate conditions. Of the continents of the
world, Africa is unique in that it stretches between the northern and southern
temperate zones. Africa is also attributed with being the birthplace of
mankind. The oldest fossil evidence of Homo sapiens was found in the eastern
part of the continent.
Africa’s large size and varying climates
make it host to many of the most interesting species of plants and animals on
Earth. There are currently more than 7,000 different species of mammals, fish,
and birds in Africa. There are more than 100,000 species of insects as well.
Here you can find both the largest ( African Elephant) and tallest (Giraffe)
animal.
There are several bodies of water
surrounding the continent of Africa. You can find the Indian Ocean to
the southeast, the Atlantic Ocean to the west, the Mediterranean Sea to the
north and the Red Sea to the northeast. The continent of Europe and Africa are
very close together. They are only 8.9 miles(14.3 km) apart on the northwest
corner of Africa. At 4,352 miles long, the Nile River is
the longest river in the world and runs along the northeast side of the
continent.
Antarctica
Land Area of Antarctica: 5,405,000 (mi²) / 12,949,940 (km²)
Population of Antarctica: 4,912 (2015)
Largest City in Antarctica: McMurdo Station (1,258 (2013))

The continent of Antarctica is positioned
as the southernmost land mass on Earth. The South Pole can be found here among its
large permanent glaciers and frigid weather. Even though Antarctica has one of
the harshest climates and most unwelcoming terrains on planet Earth, there are
still nearly five thousand people that temporarily call this continent home
every year. This makes Antarctica the least populated continent on Earth.
Antarctica is known as the coldest landmass and has few native plants or
animals because most of the continent is covered in sheets of ice that can be
more than a mile thick which forms permanent glaciers. You can find penguins,
seals, plants, and fungi in Antarctica. Interestingly, this continent is the
only one which has no reptiles on its land mass.
Antarctica is the 5th in terms of size
compared to the other 7 continents. Both Australia and Europe could fit in the
same area that Antarctica covers. The continent is known for being extremely
dry which qualifies it as the largest desert region in the world. Antarctica has one of
the windiest and coldest climates of the world’s continents. Temperatures can
reach −90°C (−130 °F) in some regions of the continent.
Asia
Land Area of Asia: 17,210,000
(mi²) / 44,029,797 (km²)
Population of Asia: 4,494,302,221 (2016)
Population of Asia: 4,494,302,221 (2016)
Largest City in Asia: Tokyo, Japan
(37,126,000 (2012))
Asia covers nearly 9 percent of the earth’s
surface making it the largest of the continents. It is also the home to
the most people with an estimated population of 4.3 billion as of 2015 which
represents nearly 60% of the world’s population. With this many people, Asia is
attributed with being a vital part of the world’s economy. Asia covers nearly
10% of the planet’s surface area and is loosely defined as the eastern portion
of the Eurasia continent with the border following a line north from the Aegean
Sea to the Black Sea to the NW corner of the Caspian Sea to the Ural River into
the Arctic Ocean. The continent is primarily positioned within the northern
hemisphere along the eastern portion. On the eastern border, you will find the
Pacific Ocean, along the southern border you will find the Indian Ocean, and you
can find the Arctic Ocean along the northernmost border.
Australia:
Land Area of Australia: 2,970,000 (mi²) / 5,179,976 (km²)
Population of Australia: 39,901,000
(2016)
Largest City in Australia: Sydney, Australia (4,921,000 (2015))
The continent of Australia includes the
mainland of the country Australia and the island regions of New Guinea,
Tasmania, and Seram. During ice ages, when much of the world’s water was frozen
in glaciers, the Australian mainland was connected by land bridges to these
islands. Australia is the smallest of the 7 continents but is home to the sixth
largest country which is known by the same name, Australia. The continent gets
its name from the latin word ‘australis’ which translates to mean southern. As
a result of the continent’s geography and size, it is often referred to as an
“island” continent. Australia is surrounded by two oceans. The Indian ocean is
found on the western side and the pacific
ocean is found on the eastern side.
Australia is the most isolated and remote
continent of the 7 continents and has been least influenced by migrations of
people, plants, and animals. This had led to Australia having a wide variety of
animals and plants which are unique in the world such as the kangaroo, koala,
dingo, wallaby, and wombat. Of the 5,700 hundred species of animals on the
continent of Australia, more than 80% are unique and cannot be found anywhere
else in the world. The continent is also home to the world’s largest reef and
one of the greatest natural wonders, The Great
Barrier Reef.
The continent first was inhabited by man
nearly 45,000 years ago. European inhabitants came onto the Australian landmass
in the 1700’s. Australia is one of the least populated continents yet the
country of Australia is the 12th largest economy in the world.
Europe:
Land Area of Europe: 3,931,000 (mi²) / 7,769,964 (km²)
Population of Europe: 738,849,000 (2016)
Largest City in Europe: Istanbul, Turkey (14,657,434 (2016))

The western portion of the Eurasian landmass
is known as Europe. It is noted as one of the smallest of the 7 continents
after Australia, with 7 percent of the world’s landmass. However, Europe is
home to about 11% of Earth’s population and is the second most densely
populated continent, with 134 people per square mile, behind Asia’s 203 people
per square mile.
Europe is comprised of approximately 50
countries and several other territories. The country of Russia is the largest
country and the area that is occupied by Vatican
City in Italy is the smallest. However,
Russia has portions of its territory in both the continent of Europe and Asia
with forty percent falling in the continent of Europe. Europe, by definition,
includes the continental mainland ending in the east at the Ural Mountains in
Russia. Europe also includes islands such as Iceland, Sicily, and the British
Isles. The British Isles consist of the large island that is home to England,
Scotland, and Wales, and is called Great Britain; the British Isles also
include the small island that contains Northern Ireland and the Republic of
Ireland, and several much smaller surrounding islands.
There are several bodies of water that
surround the continent of Europe. To the south, you will find the Mediterranean
Sea and the Black Sea, to the west is the Atlantic
Ocean, and to the north is the Arctic Ocean.
Europe has played host to many historic events
over the course of history that have left a lasting effect and shaped the
continent we know today. People have been living in Europe for about 100,000
years. Around 2000 B.C., Indo-European settlers came and brought the language
that most modern European languages are descended from. The ancient Greek and
Roman civilizations flourished there, from which we get much of our learning
and culture. In the 5th and 6th centuries, the Germanic tribes swept over most
of Europe, and their descendants shaped the modern countries of Scandinavia and
west and central Europe. By this time the Roman empire had become Christian,
and eventually, all of Europe became Christian, for reasons of both faith and
economics. The diversity and size of Europe led to the continent hosting much
of World War I and : War II.
North America:
Land Area of North America: 9,540,000 (mi²) /
23,309,892 (km²)
Population of North America: 579,024,000 (2016)
Largest City in North America: Mexico City, Mexico (19,411,000 (2012))
Population of North America: 579,024,000 (2016)
Largest City in North America: Mexico City, Mexico (19,411,000 (2012))
The North American continent is the 3rd
largest continent. It includes the countries of Canada, United States,
Greenland, Mexico and the Latin American regions that serve as a connection
between North and South America. North America makes up about 17 percent of the
world’s landmass and is home to about 8 percent of the people. The continent is
found entirely in the northern hemisphere and surrounded by the Arctic Ocean to
the north, the Pacific Ocean to the West, and the Atlantic Ocean to the east.
The population of about 565 million people are
situated in about 23 independent countries. The earliest human inhabitants in
North America were from Asia and crossed into Alaska over the Bering land
bridge during an ice age. The arrival of Europeans occurred in the mid-1600s.
This population is now dominant in North America.
North America has a very diverse climate,
wildlife, and geography. From extreme desert temperatures in Death Valley to the
snow-covered mountains of Mount
McKinley to the largest freshwater lake in
the U.S. (2nd largest in the world), Lake
Superior.
North America is responsible for nearly 50% of
the world’s corn production and 1/5th of the world’s wheat production. The
continent is also an economic juggernaut with the largest GDP per capita of the
7 continents. You can also find the busiest airport in all of the 7 continents
on the North American continent at Atlanta
International Airport, in Atlanta, Georgia,
United States.
South America:
Land Area of South America: 6,888,000 (mi²) /
15,539,928 (km²)
Population of South America: 414,332,000 (2015)
Largest City in South America: São Paulo, Brazil (21,090,791 (2014))
Population of South America: 414,332,000 (2015)
Largest City in South America: São Paulo, Brazil (21,090,791 (2014))
The South American continent is the southern
portion of the larger American continent and located in the southern
hemisphere. The equator passes through the continent offering a tropical
climate for much of the landmass with temperate conditions possible in the
south. South America is surrounded by the Pacific Ocean on the western border
and the Atlantic Ocean on its eastern border. This continent is the fourth
largest of the 7 continents and is made up of twelve countries with Brazil
being the largest in terms of both land mass and population.
South America is home to incredible
biodiversity. South America includes the Andes Mountains which comprise the
longest range of peaks in the world. It is home to the Amazon River, which
passes the largest volume of water of any river in the world. You can also find
the Amazon rainforest which is the world’s largest rainforest and is host to
some of the most unique plants and animals on Earth. The continent is home to
llamas and alpacas that originally were wild but became domesticated nearly
5,000 years ago.
The indigenous people of South America may
have migrated south from North America although the majority of its current 371
million residents are of European descent. The population is largely along the
Pacific and Atlantic coasts with large portions of the inland regions hosting
small and widely spread populations. Colonization efforts by Spanish and
Portuguese explorers ultimately lead to the prevalence of those languages on
the South American continent.
