Are the continents moving?

Yes, the continents are constantly moving due to plate tectonics. The movement is very slow, usually a few centimeters per year, but over millions of years, it has resulted in the shifting positions of the continents on Earth's surface.


How did the seven continents break apart?

The breakup of the seven continents was primarily due to the process of plate tectonics. About 200 million years ago, a supercontinent called Pangaea began to break apart into smaller landmasses, eventually forming the continents as we know them today. This movement of the Earth's lithosphere plates continues to this day, with the continents shifting slowly over time.


How does sea-floor spreading provide a way for continents to move?

because if the sea-floor is moving it will probably will move a chunk of land that could be part of a continent the land at the bottom of the ocean is being spread across, and is taking space up. the continents are on tectonic plates, and need to go some where and move away.


How did pangaea spread?

Pangaea split apart due to the movement of tectonic plates over millions of years. This process, known as continental drift, caused the supercontinent to gradually break up into the continents we see today. The movement of the plates continues today, with some continents still drifting apart while others are converging.


When did Pangaea spread apart?

Pangaea refers to the super continent that existed before each of the pieces eventually drifted apart into the seven continents that exist today. Scientists believe Pangaea broke apart 200 million years ago.

What did Wegener think caused the Continents to spread apart?

An earthquake.


What happened to the joined continents?

They were spread apart over a period of time when the earth's crust was moving.


Why did dinosaurs travel to all continents?

Dinosaurs first evolved during the Triassic, when all the continents were joined together. Hence, the spread to all continents. When the continents split apart, dinosaurs still lived on all of them.


Why are dinosaur fossils in every country?

because in the time of the dinosaurs all of the continents were together in a super continent called Pangaea. Afterwards the continents spread apart taking the dinosaurs with them


How are the continental drift theory to the present positions of the continents related?

They are spread apart now because before the were one big landmass.

At what rate do continents move apart?

sea floor spreadingThe continents of South America and Africa started to spread apart when the mid-Atlantic ocean ridge started creating new oceanic crust which pushed the continents apart.


Is it true continents move?

yes, they do move, but very slowly, too slow for the naked eye can see. billions of years ago, all of the continents were squished together, but they gradually spread apart. I'm a fifth grader.


The primary source that causes the seafloor to spread and continents to drift?

In the middle of the ocean is a rift where the ocean floor squeezes out lava and pushes the ocean plates apart.

What is the Pangaea puzzle?

The Pangea puzzle is the theory of the beginning of the continents. It's how the Earth started out. Well it is the theory of how the continents came to be. The legend has it that way back in time, there weren't any continents. There was just one large landmass. Until it started to spread apart. That is when it was no longer just one piece. But there were 7 different landmasses. Over hundreds of thousands of years, those landmasses spread apart into what we know now as our 7 continents.
