The movement of tectonic plates over millions of years is responsible for the current positions of continents. Plate tectonics, a theory that explains how Earth's outer shell is divided into several plates that move across the Earth's surface, has caused continents to drift and collide, leading to the formation of the current landmass configurations.

What era did continents assume their current positions?
Mesozoic Era
Have continents always been in their current positions?
No, continents have not always been in their current positions. The movement of tectonic plates has resulted in the shifting and rearranging of continents over millions of years through a process known as plate tectonics. This movement continues to occur at a slow rate today.
The continents assumed their current positions during the era?
Mesozoic
How do the positions or the continents today compare with their positions 220 million years ago?
220 million years ago, the Earth's landmasses were connected in a supercontinent called Pangaea. Over time, this supercontinent broke apart, leading to the formation of the continents we have today. The shifting and drifting of tectonic plates caused the continents to move to their current positions.
What processes have led to the current arrangement of the continents?
The current arrangement of continents is due to the process of plate tectonics. Continents sit on moving tectonic plates that have shifted over millions of years due to the movement of the Earth's outer shell. This process has caused continents to drift apart, collide, or slide against each other, leading to their current positions.

What did wegner hypothesize happened to the continents?
Wegner hypothesised that the continents 'drifted' into their current positions over time and originally formed one supercontinent.
The continents assumed their current positions during the era?
Mesozoic
As hypothesized by Alfred Wegener what is the history of Earth's continents?
They were joined together, then drifted apart to their current positions
What creates surface current?
Surface currents are created by air currents, earth's rotation, and positions of the continents.
What processes have led to the current arrangement of the continents?
The current arrangement of continents is due to the process of plate tectonics. Continents sit on moving tectonic plates that have shifted over millions of years due to the movement of the Earth's outer shell. This process has caused continents to drift apart, collide, or slide against each other, leading to their current positions.
Are the continents interconnected?
Yes, the continents are interconnected through plate tectonics. Over millions of years, the movement of tectonic plates has brought the continents to their current positions. This movement continues to shape the Earth's surface.
What do the glossopteris fossils tell us about early positions of the continents?
That they must have been joined up in the past because the same fossils could not exist on the continents given their current position.
What do the glossopteris fossils tell us about the early positions of the continents?
That they must have been joined up in the past because the same fossils could not exist on the continents given their current position.
What is the fit of the continents called?
The fit of the continents is called continental drift, which refers to the theory that Earth's continents were once all connected in a single supercontinent called Pangaea, before breaking apart and moving to their current positions.
How did the continents move from pangaea to their current location?
The movement of continents from Pangaea to their current locations was driven by the process of plate tectonics. This movement occurred due to the interactions of tectonic plates in the Earth's lithosphere. Over millions of years, the plates shifted and drifted, leading to the separation and rearrangement of the continents into their current positions.
