How has earths appearance changed since pangaea?
the continents have broken up from the continental drift
What was the process that broke up Pangaea called?
The process that broke up Pangaea is known as continental drift. This theory states that the Earth's continents were once joined together as one supercontinent and have since drifted apart to their current positions.
What did wegener name his supercontinent?
Wegener named his supercontinent "Pangaea," which means "all lands" in Greek. He proposed the theory of Pangaea to explain how the continents once fit together and have since drifted apart due to plate tectonics.
What split Pangea?
the plate tectonics. the plates were (and still are) moving which caused the supercontinent to split apart and come into the places where they are today. someday, since the plates are still moving, all the continents will come together again and form another supercontinent.
How has earths surface changed since the beginning of earths time?
The continents have moved, Volcanoes and mountains have made hige changes in the earths suface too.

What has happened since pangaea?
Since Pangaea, the supercontinent has broken apart into separate land masses, leading to the formation of the continents we recognize today. This process, known as continental drift, has shaped Earth's geography and influenced the evolution of life on the planet. Additionally, the movement of tectonic plates continues to reshape the Earth's surface through processes like subduction, seafloor spreading, and mountain-building.
Explain how the reversal of earths magnetic poles can be produce a calendar for part of earths history?
In rock formed when the sea floor is being built, such as at the mid-Atlantic ridge, the minerals preserve the magnetic polarity. Since the flipping of the poles is fairly regular, the count of the bands can give a time.
What does this suggest about when these particular continents broken up?
The presence of similar fossils and geological features across continents suggests that they were once connected and have since drifted apart due to plate tectonics. This likely occurred over millions of years, following the breakup of the supercontinent Pangaea around 175 million years ago.
