What does ocean crust mean in science?
The oceanic crust is the part of the earth's crust that is below the ocean. The rock that makes up the oceanic crust is about 200 million years old.
How is new crust formed?
New crust is formed along boundaries between tectonic plates which are moving apart. Most crust creation takes place on the ocean floor at the mid-ocean ridges. As the plates move apart, solidifying magma rises, filling fractures and openings created by the divergence. Some lava also spills out into the seawater, creating pillow basalts on the seafloor. The entirety of the oceanic crust has, and is, being created in this manner.
Where is the new ocean crust formed?
mid-ocean ridge
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.
Does theory continental drift state that new ocean crust is formed at ocean ridges and destroyed at deep sea trenches?
No, the theory is that Seafloor spreading state that the new ocean crust is formed at ocean ridges and is destroyed at deep sea trenches.
Is ocean crust formed at a mid ocean ridge?
Yes, the process that creates oceanic crust on a mid-ocean ridge is called "seafloor spreading". seafloor spreading creates a new oceanic crust that forms on the mid-ocean ridge.
Is new oceanic crust formed at mid-ocean ridges?
Yes, the process that creates oceanic crust on a mid-ocean ridge is called "seafloor spreading". seafloor spreading creates a new oceanic crust that forms on the mid-ocean ridge.
What term describes the process that creates new oceanic crust at mid ocean ridges?
Sea Floor Spreading
If molten magma oozes out of the ocean floor and creates additional crustal material what will happen if there comes a time when there is too much crust?
New crust sometimes rides over existing crust, burying it, and sometimes it folds up, creating mountains.
What is a good sentence for sea floor spreading?
Sea floor spreading mean the process by which molten material adds new oceanic crust to the ocean floor
Is a new ocean crust formed at a divergent boundary?
because the molten rock cools in the water and forms a oceanic crust
The process that permits new ocean crust to form as molten rock from the mantle wells up between two oceanic plates that have moved away from each other?
Plate
What is part of molten rock at mid-ocean ridges?
Molten rock at mid-ocean ridges is the result of sea-floor spreading. WRONG

What process did harry hess discover to make alferd wegners theory more accepted?
He discovered that the ocean floor moves like a conveyor belt, carrying the continents with them. This process begins at the mid-ocean ridge. Old oceanic crust go back to the mantle through trenches and molten material comes out of the mid-ocean ridge, making new crust. Harry Hess called this constant process sea-floor spreading.
Describe how molten rock can form new oceanic crust?
Some of the molten rock overflows onto the ocean floor in tremendous eruptions. material from the mantle canwell up, forming a ridge and new oceanic crust.
WHAT is the the composition of earth's crust?
Many different minerals are found in oceanic crust. Feldspar, basalt, pyroxene, and other molten rock materials make up the composition of the ocean's crust.
