What is the process that creates new ocean crust to form molten rock?
Sea Floor Spreading
Why is the earth 4.6 billion years old but the oldest sea floor is only 180 millions years old?
Just as new sea floor forms at mid-ocean ridges, new sea floor is forced back into the mantle at abduction zones. The oldest seafloor is at east and west the edges of the Atlantic Ocean, dating to the breakup of Pangaea.
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.
What is the primary site for sea floor spreading?
Sea floor spreading occurs at mid-ocean ridges
How does sea floor spreading make the continents move?
Under the oceanic crust is the layer of the earth called the mantle. This layer is moving rock that is very, very hot! As the hot material in the mantle pushes up through the crust in the sea floor, it cools and becomes new crust as it pushes out (spreads) the sea floor. This movement in the plates causes other plates (continental and oceanic) to move as well. This is how sea floor spreading causes continents to move.
How does new ocean floor form?
Sea Floor Spreading!
Where does the new rocks form on the sea floor?
Forms by lava from volcanoes on the sea floor
Where does new rock form on the floor?
Forms by lava from volcanoes on the sea floor
What happens in sea-floor spearding?
new rocks form
What pushes up through rifts in the ocean floor and cools to form new sea floor?
sea floor spreading, boo. it's molten rockk from earth's coree. hope it helpped!! :)
What is the process that creates new ocean crust to form molten rock?
Sea Floor Spreading
Process in which new sea floor forms as older sea floor is pulled apart?
sea-floor spreading
How is the sea floor able to spread?
the sea floor separates. magma comes up the crack forming new sea floor
What process in which new sea floor forms as older sea floor is pulled apart?
Seafloor spreading where new floor is formed. Subduction zone where older floor is pushed back into the mantle.
The process by which molten material adds new oceanic crust to the ocean floor?

What is a process in which new sea floor forms as older sea floor is pulled apart?
Plate tectonics.
Where is new sea floor created?
the ridges
