Process in which new sea floor forms as older sea floor is pulled apart?
sea-floor spreading
What is the Process that forms new ocean floor?
Extrusive igneous rock- Sometimes lava erupts and flows from long cracks in the earths crust called fissures. Lava flows from fissures on the ocean floor at places where tension is causing the ocean to be pulled apart. This lava cools to form new ocean floor. Hope it helps.
What is the process in which new sea floor forms as other older sea floor is pulled apart?
Seafloor Spreading created by harry hess
What forms the elevated part of the earths crust?
continental crust
Earth does not get bigger as new oceanic crust forms?
Just as new oceanic crust forms at mid-ocean ridges, old oceanic crust is destroyed at subduction zones.
New crust forms on the ocean floor due to what process?
Plate tectonics.
Which geologic feature forms when central crack forms where a thin section of earth's crust breaks and molten rock seeps out?
a volcano
What is the surface of the planet that forms the continents and ocean floor?
The crust.
which layer of the earth forms ocean floor?
Ocean Crust.
How does a trench forms?
They form when the oceanic crust goes under the Continental crust. The oceanic crust then forms the trenches through a process called subduction.
What provides geologist with evidence of earths past including geologic events and life forms?
The rocks of Earth's crust, especially sedimentary rocks
How can the ocean crust be different ages?
On geologic time scales, new oceanic crust is constantly being formed ad mid-ocean ridges while older crust is destroyed at subduction zones. The crust forms at the ridge and is carried away by the movement of the plate as new crust forms to take its place. The oceanic crust is youngest new a mid ocean ridge and oldest far away from it.

What does it mean if crust forms around your piercing?
Crust forming around your piercing is part of the healing process. Do not pick the crust off as it will reopen the wound.
New crust forms?
New crust forms at spreading zones like the Mid-Atlantic ridge in the middle of the Atlantic Ocean. They occur because of ocean floor spreading.
What is called when new crust forms where magma rises at mid ocean ridges?
sea floor spreading
