How the position of the continents has changed over time?
The position of continents has changed over time due to plate tectonics. Continents have moved through processes like seafloor spreading, where new crust forms at mid-ocean ridges, and subduction, where crust is pulled back into the Earth’s mantle. Over millions of years, these movements have created the current positions of the continents on Earth’s surface.
What are the present shapes of the continents?
The continents are currently in their present shapes due to the movement of tectonic plates over millions of years. The Earth's surface is divided into several major plates that are constantly shifting, causing the continents to move and change position. This movement, known as plate tectonics, is responsible for the current shapes and positions of the continents.
What did the continents get there current position?
Continents have moved and continue to move due to the process of plate tectonics. This is driven by the movement of Earth's outer shell, which is divided into several large and small plates that glide over the mantle beneath them. The movement of these plates causes the continents to gradually shift positions over millions of years.
What do the shape of the continents now tell us about their past?
The current shape and position of continents provide evidence for the theory of plate tectonics, which suggests that continents were once part of a supercontinent called Pangaea that has since drifted apart. This movement helps explain the similarities between the geology and fossils of now widely separated continents, as well as the presence of matching coastlines and mountain ranges.
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 other theories try to explain the current position of earths continents?
Magnetic orientaion
What do the glossopteris fossils tells us about the early position 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 scientists believe will happen with the current position of th continents during and at the end of another 50my?
They will still be together
What do scientists believe will happen with the current position of the continents during and at the end of another 50 million years?
they will all be together

What do the glossopteris fossils tell us about the early position of the continents?
shows that all three continents were once connected (joined) together. because the 'exact' same fossil types were found in all three different continents, which are now split from each other.

What is it deflects the ocean current?
Continents.
What force caused the movement of the continents from one super-continents to their present position?
Continental drift :)
