Sea floor spreading
What else can I help you with?
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.
How convergent continental crust can lead into oceanic plates?
Convergent continental crust can lead to the formation of oceanic plates through a process called subduction. When two tectonic plates collide, the denser oceanic plate is forced beneath the less dense continental plate, creating a subduction zone. As the oceanic plate descends into the mantle, it can partially melt and contribute to volcanic activity on the continental crust. Over time, this process can lead to the creation of new oceanic crust as the material is recycled and reformed.
What causes oceanic ridges?
Oceanic ridges are caused by the divergent movement of tectonic plates. As the plates move apart, magma rises from the Earth's mantle to fill the gap, creating new oceanic crust. This process is known as seafloor spreading.
Process that forms new seafloor?
The process that forms new seafloor is called seafloor spreading. It occurs at mid-ocean ridges where new oceanic crust is created through volcanic activity. As magma rises and solidifies, it adds to the seafloor, pushing older crust away from the ridge and creating a continuous process of crust formation.
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 are oceanic crust and lithosphere formed?
Oceanic crust and lithosphere are formed at mid-ocean ridges through the process of seafloor spreading. Magma rises from the mantle and solidifies to create new oceanic crust at these divergent plate boundaries. As the new crust forms, it pushes the older crust away from the ridge axis, creating a continuous process of crust formation and movement.
What happens at a mid-ocean ridge and how does it contribute to the formation of new oceanic crust?
At a mid-ocean ridge, tectonic plates move apart, allowing magma from the mantle to rise and solidify, creating new oceanic crust. This process, known as seafloor spreading, contributes to the continuous formation of new oceanic crust and the expansion of the ocean floor.
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.
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.
Where new crust is being formed?
New oceanic crust is continually being created at the Mid-Ocean ridges.

What causes oceanic ridges?
Oceanic ridges are caused by the divergent movement of tectonic plates. As the plates move apart, magma rises from the Earth's mantle to fill the gap, creating new oceanic crust. This process is known as seafloor spreading.
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 feature forms at diverging oceanic plates?
Mid-ocean ridges form at diverging oceanic plates. As the plates move apart, magma rises to fill the space, creating new oceanic crust. This process results in the formation of underwater mountain ranges along the divergent boundary.
Does seafloor spreading cause the earth's crust to expand?
Yes, seafloor spreading is a process where new oceanic crust is formed at mid-ocean ridges, causing the Earth's crust to expand. This occurs as magma rises to the surface, solidifies, and pushes older crust away from the ridge, creating new seafloor.
Process that forms new seafloor?
The process that forms new seafloor is called seafloor spreading. It occurs at mid-ocean ridges where new oceanic crust is created through volcanic activity. As magma rises and solidifies, it adds to the seafloor, pushing older crust away from the ridge and creating a continuous process of crust formation.
Is the sea floor spreading constructive or destructive?
Sea floor spreading is considered a constructive process because it involves the formation of new oceanic crust at mid-ocean ridges. As tectonic plates move apart, magma rises to the surface and solidifies, creating new crust. This process helps in the continuous renewal of the oceanic lithosphere.
