Ep. 113: The 7 Continents in Order of Size — The Mnemonic Tree Podcast (2024)

Intro

Hello and Welcome to this episode of the podcast, "The Mnemonic Tree", where we add a single mnemonic leaf to our Tree of Knowledge.

I’m Jans you Mnemonic Man and today's episode is on seven continents of planet Earth. Essentially evolving from the one giant land mass called Pangaea about 299 million years ago, the seven continents have been millions and millions of years in the making and continue to create a different picture moving at an average of 1.5 centimetres per year.

Each continent is rich with history, culture, flora, fauna, and magnificent landscapes but only one continent can claim both continent and country status and that is the land down under.

Today’s mnemonic is on the seven continents in order of size from largest to smallest.

So, with that being said, we will begin with a summary from Wikipedia.

Wikipedia Summary

Acontinentis any of several largegeographical regions. Continents are generally identified byconventionrather than any strict criteria. A continent could be a singlelandmassor a part of a very large landmass, as in the case of Asia or Europe. Due to this, the number of continents varies; up to seven or as few as four geographical regions are commonly regarded as continents. MostEnglish-speaking countriesrecognize seven regions as continents. In order from largest to smallest in area, these seven regions areAsia,Africa,North America,South America,Antarctica,Europe, andAustralia.[1]Different variations with fewer continents merge some of these regions; examples of this are merging North America and South America intoAmerica, Asia and Europe intoEurasia, and Africa, Asia, and Europe intoAfro-Eurasia.

Oceanic islandsare frequently grouped with a nearby continent to divide all the world's land into geographical regions. Under this scheme, most of the island countries and territories in thePacific Oceanare grouped together with the continent of Australia to form the geographical regionOceania.[2]

Ingeology, a continent is defined as "one ofEarth's major landmasses, including both drylandandcontinental shelves".[3]Thegeological continentscorrespond to seven large areas of continental crust that are found on thetectonic plates, but exclude smallcontinental fragmentssuch asMadagascarthat are generally referred to as microcontinents. Continental crust is only known to exist on Earth.[4]

The idea ofcontinental driftgained recognition in the 20th century. It postulates that the current continents formed from the breaking up of a supercontinent (Pangaea) that formed hundreds of millions of years ago.

The 7 Continents in Order of Size Mnemonic – Asia & Africa are North & South And Europe Alone

(Picture Asia above Africa as most of it is and Europe out there all alone)

1. Asia

2. Africa

3. North America

4. South America

5. Antarctica

6. Europe

7. Australia

Five Fun Facts

1. As many would know back in the old days (about 299 million years ago) there used to be only one continent. That continent or large mass of land was called Pangaea.

2. About 200 million ago this continent began to move apart and very slowly form the continents as we know them today.

During that process of moving apart about 200 million years ago, the continent of Pangaea separated into two new continents called Laurasia and Gondwanaland.

Laurasia was made up of the present-day continents of North America, Europe, and Asia and Gondwanaland was made up of Antarctica, Australia, and South America.

3. The largest continent Asia also contains the highest population with 4.1 billion people. This is approximately 60% of the world’s population and 3.1 billion more than the second most populated continent.

4. It is generally agreed there are seven continents however, it is often argued that Europe and Asia should be one continent called Eurasia. North and South America should also form one continent called the Americas and Africa, Asia, and Europe could possibly be linked to formAfro-Eurasia.

5. The idea of continental drift was put forward by Alfred Wegener in a meeting of the Geological Society in 1912 in Frankfurt, Germany. He then published this theory in his 1915 book “The Origin of Continents and Oceans”. Unfortunately, the idea was ridiculed and forgotten and it wasn’t until the 1960’s when it was revisited with the help of more advanced equipment that his theory was then validated.
