Physical Characteristics of Planet Earth Wiki This wiki stands to serve the purpose of informing you about the Physical Characteristics of Planet Earth.
Land masses and water bodies Edit
Continents are very large land masses. There are seven continents on the earth namely:
Asia Africa, North America, South America, Antarctica, Europe and Australia.
Size in square
|South America||17 767 331|
|Asia||48 393 963|
|Africa||30 300 293|
|North America||24 436 555|
|Antarctica||13 726 947|
|Europe||13 986 280|
|Australia||7 768 000|
Islands are small land masses completely surrounded by water. It may be very large as Greenland or as small as the Caribbean islands. A string of islands is called an archipelago. The Caribbean archipelago is one example.
Oceans, Seas and Rivers
Oceans are large sheets of salt water which border the continents. There are five oceans: Atlantic Ocean, Indian Ocean, Pacific Ocean, Arctic, and Southern Ocean. The Pacific Ocean covers approximately one half of the earth’s surface.
Size in Square Kilometre
|Atlantic Ocean||82 217 000|
|Indian Ocean||73 481 000|
|Pacific Ocean||165 384 000|
|Arctic||14 o56 000|
|Southern Ocean||20 300 000|
A sea is a sheet of salt water usually connected to an ocean. Example the caribbean sea is connected to the Atlantic Ocean.
Rivers are bodies of fresh water flowing through a channel from a source to a mouth.The source of the river is usually located in a highland area or a mountain and the mouth is usually found at the coast. Some rivers on the continents are so long and so wide that large ships sail on them. Rivers like the mississippi in North America and the Rhine in Europe are used heavily as a transport routes. Rivers are valuable to humans in other ways because they provide water that satisfies a number of our needs, and they contain a varity of fishes that supply us with foods.
|River||Continent||length in kilometres (km)|
|Mississippi||North America||6 020|
|Amazon||South America||6 516|
