The continents and ocean floor are unstable because the plates of the lithosphere move. When the plate move, they cause the continents and ocean floor to move.
What else can I help you with?
Iron rich volcanic rock that makes up much of the ocean floor is?
Basalt is the iron-rich volcanic rock that makes up much of the ocean floor. It forms from the cooling and solidification of magma that erupts through underwater volcanic activity, such as mid-ocean ridges. Basalt is a key component of Earth's oceanic crust.
What type igneous rock makes up most of the ocean floor?
Basalt
Is the floor near the mid ocean old?
No. The newest ocean floor is at the mid-ocean ridge.
What is the floor of the ocean called?
The floor of the ocean is called the seabed or ocean floor. It is made up of different features such as abyssal plains, trenches, ridges, and volcanoes.
What is the underwater edge of a continent called?
You can't have a continent rise from land, but you can have land rise from the continental shelf, which may be under water, and that is called an island.
What is the part of the ocean floor nearest the continent?
Continental Shelf.
Which feature of the ocean floor is shallow and close to the edge of the continent?
pie
What feature is being created at the continent and the ocean floor?
Molten meaterial
Means the ocean floor is pulled under the continent?
This occurs in a subduction zone.
What happens to the old ocean floor as the sea floor spreads?
As the sea floor spreads, the old ocean floor gets pushed out, which makes the plates move.
The point at which the continent stops and the rock of the ocean floor begins is the called the continental?
Slope
The point at which the continent stops and the rock of the ocean floor begins is called the?
Continental Slope
What continent do the cayman islands belong?
Islands in an ocean don't belong to any continent. If they were part of a continent they wouldn't be islands would they? The African Continent is the continent nearest the Canary Islands, but the islands are the result of volcanic activity on the ocean floor.
A rock that makes up much of the ocean floor?
basalt
What is an ocean to continent boundary?
An ocean to continent boundary is where the oceanic crust meets the continental crust. This typically occurs at a continental shelf, which is the gently sloping transition between the continent and the ocean floor. This boundary is marked by significant differences in physical and geological characteristics between the two crust types.
A sharp drop from a continent to an ocean basin is called what?
A sharp drop from a continent to an ocean basin is called a continental slope. This feature marks the boundary between the continental shelf and the deep ocean floor.
What is a transition zone between a ocean basin floor and a continent?
The transition zone between an ocean basin floor and a continent is known as the continental shelf. It is the submerged part of a continent that extends from the shoreline to the continental slope. The continental shelf is characterized by relatively shallow waters and is an area of high biological productivity.
