During the Tertiary period, the Earth's continents were continuing to drift apart due to plate tectonics. This movement led to the modern configuration of continents that we see today. The Tertiary period also saw dramatic shifts in climate and the diversification of mammals.
During the Tertiary period, Earth's continents were continuing to drift apart due to plate tectonics. This movement led to the formation of new mountain ranges and the reshaping of landmasses. The configuration of the continents during this time was closer to their current positions compared to earlier periods.
During the Tertiary period, which lasted from about 66 million to 2.6 million years ago, the continents were already in positions similar to today but with some differences. For example, North America and Eurasia were connected via the Bering land bridge, and South America was still drifting towards its collision with North America. Antarctica was largely ice-free, while Australia was closer to Antarctica.
Because of the lack of tectonic activity, compared to the rest of the continents. Which means features from early parts of Earths history have managed to survive, and have not been destroyed in late-Tertiary and Quaternary uplift and extensive glacial erosion that the other continents went through.
There are 7 continents: Africa, Antarctica, Asia, Europe, North America, Australia (Oceania), and South America.
The term "big continents" is not a specific geographical term. However, the biggest continents on Earth are Asia, Africa, and the Americas. These continents are large landmasses that are significant in terms of size and population.

Tertiary - Third So the tertiary comes third.
Earth's geography changed dramatically between the beginning and the end of the Tertiary. I could give you a long winded description, but I think you would prefer maps. Under "Related Links" there will be a map for the early Tertiary (called the Paleogene), and one for the later Tertiary (Neogene). P.S. The Tertiary began 65.5 million years ago and ended 2.6 million years ago.
