Web22 de jul. de 2024 · How can the ocean floor be created and/or destroyed? New crust is created due to seafloor spreading. When the plates spread magma is forced through the cracks and cools forming new land. At subduction zones where plates meet some crust can be forced underneath other crust causing the destruction of ocean floor.
WebResearchers think that the oceans formed as a result of a process known as “degassing.”. When the earth was first formed, its temperature was well above the boiling point for water. Because of this, there was no liquid water on earth. Instead, all water was in the form of a gas. A side note: this water was believed to be squeezed out of the ...

WebWell, new sea floor is constantly being created too. This happens when two tectonic plates move away from each other at a divergent boundary. When two plates diverge in the middle of an ocean, it creates a kind of underwater mountain range called a mid-ocean ridge.
