What happens to old oceanic crust as new oceanic crust forms?

Answer 1

the twinkies make their seves a mansion with it. Without their old oceanic crust they would be dead like a drug addict without drugs, a cat without a heart, a Baseball without a bat, a bus without fat kids, a fat kid without food, a granny without her gun, a twinkie without its angelic cream, in other words DEAD, USELESS. Oh how they love their old oceanic crust just like i SIMPLY ADORE MY TWINKIES without them i would be hopelessly lost in this cruel world with out my amazing twinkies which help keep me alive.

Answer 2

Since this is a two part question, I'll answer each part separately.

*How is new ocean crust formed?
New ocean crust is formed by divergent plate boundaries, at which two lithospheric plates move apart in opposite directions. As the plates separate, material from the mantle (magma) is forced upward. As it approaches and reaches the surface, it cools to create new seafloor.

*How is old oceanic crust destroyed?
Oceanic crust is destroyed at convergent boundaries, where oceanic and continental plates collide. The oceanic plates are forced under the continental plates, where the eventually reach the sweltering heat of the Earth's interior and melt. The material is then recycled back into the magma of the asthenosphere, and is eventually resurfaced at divergent plate boundaries.

Mid Atlantic Rift

Answer 3

New crust is formed by the spreading along a divergent boundary between plates. Old crust can be destroyed by subduction, or the pushing down of an oceanic plate below an overriding plate at a convergent boundary. The initial phase of a divergent boundary is a rift valley, which progresses to form an oceanic basin with a mid-oceanic ridge.

Answer 5

Old oceanic crust is usually pushed away from the mid-ocean ridge by the formation of new oceanic crust through seafloor spreading. As it moves away, it cools, contracts, and becomes denser, eventually sinking beneath the overriding tectonic plate in a process known as subduction. This recycling of oceanic crust is part of the continuous process of plate tectonics.

Answer 6

Ocean crust formed, called constructive margins and destroyed, called destructive margins are most offen happening in the ocean.
