How is call the Regions where the continents or the sea floor are pulling apart?

The sea floor is spreading because of two tectonic plates are moving apart. The technical name for this area is a divergent boundary. In this area rifts are created, and some may apply this term to what is the divergent boundary. A link is provided to the relevant Wikipedia article.

add. And this process is not confined to the sea. The Great African Rift Valley is one such and one day will become connected to the sea.

What is spreading in regards to geology?
Spreading is generally thought of when speaking of sea-floor spreading. Sea-floor spreading takes place at the mid-ocean ridge where two oceanic plates are spreading/pulling apart from one another.
The topography of the ocean floor?
Is a diverse as that of the continents
How did Pangaea break?
Pangea broke apart because the earths plates (crusts) began to shift under, over, together, and apart from other plates.The continents were moved as the rocks undearneath them moved as a result of earth's boundaries and the growing of the ocean's floor and its reduction.
What is the primary force that causes the sea floor to spread and continents to drift?
Radiologyinfotation
Why was wegeners theory ignored until the mid 1960s?
Alfred Wegener tried to explain how continental drift took place, but he had no concrete evidence about how the continents moved. He had to explain what force is pushing and pulling the continents. And mainly in the early 1900s, most geologists thought that mountains formed because Earth was slowly cooling and shrinking. So most geologists would have to change their ideas of how mountains formed. Then in 1960 Harry Hess, an American geologist, he thought about the ocean floor in relation to the problem of continental drift. He proposed a process called sea-floor spreading. In sea-floor spreading, the sea floor spreads apart along both sides of a mid-ocean ridge as new crust is added. The ocean floors move like conveyor belts, carrying the continents with them. Hess soon found evidence from molten material, magnetic stripes, and rock samples from the mid-ocean ridges. And he proved that Wegener's theory wasn't wrong.
What are regions where the continents or the sea floor are pulling apart called?
rift zones
How does the movement of tectonic plates and continents relate?
When the plates drift apart through sea floor spreading, so do the continents
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.
How do plates play a role in Pangaea changing into 7 continents?
Plates play a role in Pangaea changing into 7 continents because there are 7 major plates in the world. These plates are being moved by sea-floor spreading, pulling the continents along with them.
How sea floor spreading provides a mechanism by which continents move?
The fact that plates move apart means that the plates will carry anything.
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 is composed of the continents and the oceans floor?
Earth's crust is composed of the continents and the ocean floor.
Is the age of the sea floor the same age of the continents?
No. The sea floor is much younger than the continents. The oldest sea floor is about 200 million years old. The continents are billions of years old.
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.
Is the sea floor smooth and level?
Yes, in many places it is. But like the surface of the earth that you can see, the ocean floor has many different topographies. The ocean floor has mountains, volcanoes, deep valleys, and reefs. There vast areas of vegetation and areas that are devoid of vegetation, often due to how deep they are and how much sunlight penetrates. There are also arctic regions of ocean floor as well as tropical regions. The ocean floor is really as varied as the continents above the water.
What are the steps in the sea floor spreading?
In sea-floor spreading,the sea floor spreads apart along both sides of the mid-ocean ridge as a new crust is added.As a result,the ocean floors move like conveyor belts,carrying the continents along with them.
What is the cycle of the mid ocean ridge?
When gravity pushes down on the floor it causes ridge pressing. Ridge pressing pries the the sea floor apart causing the magma to come up out of the mantle to cool and create a new crust. Not only does it create a new crust but it pushes the continents father apart. That is why over time they grow father and farther apart.
