Why is it important to have knowledge of all seven continents?
Oceans & Continents of the World Geographical location provides us with context. It’s important to know where the seven continents are located and what their characteristics are. It’s also important to know where the world’s five oceans are.
Why are the shapes of the continents important?
The idea that the continents move about the surface of the planet is an old one. It was formulated initially to explain the striking parallels of the shape of the Atlantic coast of Africa with that of South America. The shape of these continents suggests that they would fit together well.
How do you identify the ocean?
Historically, there are four named oceans: the Atlantic, Pacific, Indian, and Arctic. However, most countries – including the United States – now recognize the Southern (Antarctic) as the fifth ocean. The Pacific, Atlantic, and Indian are the most commonly known. The Southern Ocean is the ‘newest’ named ocean.
How do you identify a continent?
Generally identified by convention rather than any strict criteria, up to seven geographical regions are commonly regarded as continents. Ordered from largest in area to smallest, these seven regions are: Asia, Africa, North America, South America, Antarctica, Europe, and Australia.
What do you know about ocean?
The ocean covers 70 percent of the Earth’s surface. It contains about 1.35 billion cubic kilometers (324 million cubic miles) of water, which is about 97 percent of all the water on Earth. The ocean makes all life on Earth possible, and makes the planet appear blue when viewed from space.
What do you observe about the shape of the continents?
What do you observe about the shape of the continents? Some of the continents look as if they fit together like the pieces of a puzzle. It split apart millions of years ago and the continents moved to their present position.
What do the shapes of the continents?
The distribution of the seven continents. More than two-thirds of the Earth’s land surface lies north of the Equator, and all the continents except Antarctica are wedge shaped, wider in the north than they are in the south.
Why are oceans important?
The air we breathe: The ocean produces over half of the world’s oxygen and absorbs 50 times more carbon dioxide than our atmosphere. Climate regulation: Covering 70 percent of the Earth’s surface, the ocean transports heat from the equator to the poles, regulating our climate and weather patterns.
What is a continent and an ocean?
A continent is one of Earth’s seven main divisions of land. The continents are, from largest to smallest: Asia, Africa, North America, South America, Antarctica, Europe, and Australia. The ocean covers almost three-fourths of Earth. The area of the ocean is more than double the area of all the continents combined.
What are the seven continents of the world?
These continents are made up of many countries and they include Antarctica, Africa, Asia, Europe, Australia, South America, and North America. Below are the details of the 7 continents of the world.
What is the relationship between the continents and the oceans?
The oceans are far thinner than the continents and fill the surface gaps between the continents. Both, as part of the crust (there is continental crust and oceanic crust), are a part of the lithosphere, which in turn, floats on the asthenosphere, which is a ”liquid” layer at the top of the Earth’s mantle.
What is the importance of the ocean to our planet?
Holding 97\% of the water of our planet, almost all rain that drops on land comes from the sea. The ocean absorbs CO2, to keep the carbon cycle, and accordingly temperatures on earth, in balance. It is like our global climate control system. 3. It is an important source of food.
Which continent is also known as the island continent?
It is also known as the island continent owing to its isolated location and small size. Australia is situated in the Indo-Australian plate and it is encircled by the Pacific Ocean and the Indian Ocean.
