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?
This process is called seafloor spreading. It occurs at mid-ocean ridges, where two oceanic plates diverge, allowing molten rock from the mantle to rise and solidify as new crust. As the plates move apart, the newly formed crust pushes older crust away from the ridge, leading to the formation of a continuous oceanic crust.
What happens when continental collides with continental crust?
The oceanic crust is force down into the mantle in a process called subduction. The subducting oceanic plate will introduce water into the hot mantle, causing some of the rock to melt. The molten rock will rise through the overriding continental crust to form volcanoes.
How does a deep-ocean trench form?
They form when the oceanic crust goes under the Continental crust. The oceanic crust then forms the trenches through a process called subduction.
Is the following sentence true or false Hot spots form only under oceanic crust?
false there is a famous hotspot in Yellow stone, CA
What happens when oceanic crust and continental crust collide?
Subduction occurs on continental boundaries because oceanic sub floor is denser and heavier than the lighter more buoyant crust. The oceanic crust slides under the continental crust areas usually on a plate boundary. This is in a recycle style mode that constantly is remaking the ocean floor. The oldest rocks on the ocean bottom are a drop in the geologic time bucket, compared to the rock ages on land.
How does trench formed?
They form when the oceanic crust goes under the Continental crust. The oceanic crust then forms the trenches through a process called subduction.
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 happens to two oceanic crust when they collide?
the older crust is subducted and later pushed up to form oceanic arcs
Where does the oceanic crust begin?
The oceanic crust begins at the Mid-Ocean Ridge, where tectonic plates are moving apart, allowing magma to rise and solidify, forming new crust. This process of seafloor spreading creates the youngest oceanic crust at the ridge and older crust farther away from it.
Where did the crust on the Earth come from?
The Earth some times oceanic crust is formed by the process of mid oceanic ridges. this process occurs when magma comes from the mantle and cool below oceanic body & form new crust.
Is crust created or destroyed at the oceanic ridge?
Crust is created at oceanic ridges through volcanic activity where magma rises from the mantle and solidifies to form new oceanic crust. This process is known as seafloor spreading.
Where did the crust from the earth come from?
The Earth some times oceanic crust is formed by the process of mid oceanic ridges. this process occurs when magma comes from the mantle and cool below oceanic body & form new crust.
