The continents assumed their current positions during the Cenozoic Era, particularly in the latter part known as the Neogene and Quaternary periods. This movement of the continents is part of the ongoing process of plate tectonics, where the Earth's lithospheric plates shift and collide over millions of years, leading to the arrangement of the continents as we see them today.

What era did continents assume their current positions?
Mesozoic Era
How long did it take for Pangaea to separate?
Pangaea began to break apart around 200 million years ago during the Mesozoic Era. The separation process is estimated to have taken about 50-60 million years before the continents assumed their current positions.
During the Tertiary period Earth's continents were?
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.
How did the continents connect?
The continents were once part of a supercontinent called Pangaea, which began to break apart around 200 million years ago during the process of plate tectonics. Over time, the shifting of tectonic plates caused the continents to drift to their current positions, creating the continents as we know them today.
How long ago did modern continents begin to take shape?
Modern continents began to take shape around 200 million years ago during the breakup of the supercontinent Pangaea. This process resulted in the formation of the continents we see today, as they drifted into their current positions.

Over time, the shifting of tectonic plates caused the continents to drift to their current positions, creating the continents as we know them today.
How did the continents move during each of the eras?
During the Paleozoic Era, the continents were mostly joined together as a supercontinent called Pangaea. In the Mesozoic Era, Pangaea began to break apart, leading to the formation of the modern continents. Throughout the Cenozoic Era, the continents continued to move to their current positions due to the process of plate tectonics.
At the end of mesozoic era did the continents took on their modern shape?
No, at the end of the Mesozoic era, about 66 million years ago, the continents were still in the process of drifting to their current positions. It was during the Cenozoic era that the continents took on their modern shapes due to the continued movement of tectonic plates.
What is unique about the Cenozoic era?
Cenozoic Era,third of the major eras of the Earth's history, beginning about 65.5 million years ago and extending to the present. It was the interval of time during which the continents assumed their modern configuration and geographic positions and during which the Earth's flora and fauna evolved toward those of the present.
How long ago did modern continents begin to take shape?
Modern continents began to take shape around 200 million years ago during the breakup of the supercontinent Pangaea. This process resulted in the formation of the continents we see today, as they drifted into their current positions.
When did the break up at Pangaea occur?
The breakup of Pangaea began around 175 million years ago during the early Jurassic period. This gradual process resulted in the formation of separate continents that eventually drifted into their current positions.
How long ago did Pangaea split into continents?
The original super-continent of Pangaea broke up about 200 million years ago during the Paleozoic era forming the continents of Gondwanaland and Laurasia. Gondwanaland later fragmented into Antarctica, Africa, Australia, India and South America. Similarly, Laurasia broke up into Asia, Europe and North America. The current 7 continents have been more or less in their current positions for the past few million years.
When did pangaea happen?
Pangaea existed approximately 335-175 million years ago during the late Paleozoic and early Mesozoic eras. It was a supercontinent that existed before the current continents drifted apart to their present positions.
What is Pangea definition?
Pangaea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras, approximately 335 million years ago. It was a single landmass comprising most of today's continents before they drifted apart to their current positions. The theory of Pangaea provides evidence for the concept of continental drift.
