Continental drift theory has been replaced by the science of plate tectonics, an all inclusive explanation of the process of continent movements, crust creation, lithologies, subduction, the rock cycle, and so on.

At colliding plate boundaries, the more dense oceanic plate is subducted underneath and in a downward motion from the less dense plate, and enters the mantle. As it subducts, it pulls the plate attached to it. On the opposite side of the plate, new crust is being created by rising solidifying magma to fill the void created by the diverging plate boundary. Thus the plates are in a constant state of motion relative to each other; colliding, separating, or sliding past each other.

The engine behind plate tectonics is heat from the interior of the Earth. This heat exists due to radioactive decay as well as remnant heat from Earth's formation processes.
The continental drift is basically caused by the convection in the mantle.

What two continents are drifting apart?

The continents of Africa and South America are drifting apart due to the movement of tectonic plates along the Mid-Atlantic Ridge. This process, known as continental drift, occurs at a rate of a few centimeters per year.


Which continent are still drifting?

All of the continents are still drifting. you see all the continents have been drifting since some planet struck Earth about 3.5 billion yrs ago and our planet was turned into a great ball of lava and magma then the top cooled and the continents and the crust were both formed. ever since the continents have been drifting around the globe. In fact, there was a super continent before Pangaea but before that scientists can't tell if there was another subcontinent, but super continents prove that every continent has drift.


When did the continents drift apart to their present positions?

The breakup of Pangea started roughly 200 million years ago.


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 are the stages in a continental drift?

Well, Continental Rifting is the process in which a continent is literally pulled apart. First, sediment collects on the floor of the rift valley. Oceanic crust made of gabbro and basalt is formed, which is dense and causes the valley to sink. Eventually, ocean water flows into the valley. There you have it. Hope this Helped.

Are the continents still drifting today or did that only happen a long time ago?

They are still moving

Is Africa drifting?

all the continents are drifting


What theory that continents move apart form each other?

The action of continents drifting apart from each other is called, "Continental Drift". It is no longer a theory, as it has been proven to be so. Of course, as certain continents move apart from each other, they also are moving closer to other continents.


Why do you think the continent stop drifting?

Continents never stopped drifting. Continents are alwaysin motion, even now.


Why is the Alantic Ocean expanding?

because the continents are drifting further apart due to th oceantal crust separating under water


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.


Have the continents on opposite sides of the Atlantic ocean generally been drifting apart?

Yes. The continents have been drifting around since Earth first got her oceans, or before. At one time, there were a group of continents clustered near what is now Antarctica . . . the entire remainder of Earth's surface was covered by oceans of water. They eventually drifted apart. The current arrangement of continents occurred fairly recently in Earth's 4.5 billion year age.


What is the supercontient that later broke apart into the seven continents found on Earth today?

The supercontinent that broke apart into the seven continents found on Earth today is called Pangaea. This breakup occurred over millions of years through the process of plate tectonics, resulting in the continents drifting apart to their current positions on the planet.

Does the result of the continents drifting apart have something to do with the theory of continental drift?

yes. because of the sea-floor spreading making Africa and South America drift apart even more


What happened when pangaea broke apart?

When Pangaea broke apart, the continents began drifting away from each other due to tectonic plate movements. This led to the formation of separate landmasses that eventually evolved into the continents we see today. The movement of the continents also had a significant impact on Earth's climate, ocean currents, and biodiversity.
