Did you know that there are seven continents and five oceans? Or that the number of continents has changed over time? In this blog post, we will explore the history of continents and oceans, as well as discuss the different geographical features found on each continent. We will also take a look at some interesting facts about each continent and ocean!
What Are Continents?
A continent is one of the several large landmasses on Earth. There are seven continents: Europe, Asia, Africa, Australia/Oceania, Antarctica, North America and South America. Each of these continents has a distinct boundary that surrounds it except for boundaries that meet at some point in the ocean.
What Are Oceans?
Oceans are a large body of saltwater, covering about 71% of the Earth’s surface. Ocean water is also known as seawater. Oceans contain 97% of all the planet’s water and account for 99 per cent of its living space. Seawater has many functions such as regulating global climate by transferring heat from the tropics to the poles and moderating Earth’s temperature. Oceans also help in the production of oxygen and are a food source for many marine species.

Conclusion
The vast world includes multiple varied geographical and natural wonders. It is not always easy to remember all the facts about the topography of Earth, but remembering the basics like the names of continents and oceans is practised from childhood so it is on everyone’s fingertips by the time they grow up.
