What is the mechanism responisble for producing the new oceanic crust between 2 diverging plates?
The mechanism responsible for producing new oceanic crust between two diverging plates is seafloor spreading. Magma rises up from the mantle at mid-ocean ridges, solidifies upon reaching the seafloor, and forms new crust. As the plates move apart, this process continuously adds new material to the ocean floor.
Which force is responsible for seafloor spreading?
Gravity in the oceanic crust is responsible for seafloor spreading.
What forms at diverging plate boundaries?
At diverging plate boundaries, new oceanic crust forms through seafloor spreading. Magma rises to the surface and solidifies, creating mid-ocean ridges. As the plates move apart, they create new oceanic crust, which can lead to the formation of rift valleys.
What seafloor is the process by which new crust is created when the seafloor moves apart and magma rises up?
This process is called seafloor spreading. It occurs at mid-ocean ridges where tectonic plates are diverging, allowing magma to rise from the mantle and solidify to create new oceanic crust. As the new crust forms, it pushes the older crust away from the ridge, leading to the continuous expansion of the seafloor.
What is divergent plates?
Divergent plates are tectonic plates that are moving away from each other. As they move apart, magma rises from the mantle and creates new crust at the mid-ocean ridges. This process is responsible for seafloor spreading and the formation of new oceanic crust.

Early in this century what was the prevailing view of how land animals migrated across vast expenses of ocean?
Opponents of continental drift claimed that due to transoceanic land bridges animals were able to make their way across the oceans. Seafloor spreading is the process of producing a new seafloor between two diverging planes.

What is a result in a diverging boundary?
At a diverging boundary, tectonic plates move away from each other. This results in the formation of new crust as magma rises to fill the gap created by the separating plates. As the magma cools and solidifies, it creates new oceanic crust on the seafloor or volcanic activity on land.
What effect does a diverging boundary have on the crust?
A diverging boundary results in the separation of tectonic plates, leading to the creation of new crust through seafloor spreading. Magma rises to fill the gap between the plates, solidifies, and becomes part of the oceanic crust. This process contributes to the continuous renewal and expansion of the Earth's lithosphere.
Does seafloor spreading hold the plates in place?
No, seafloor spreading does not hold the plates in place. Seafloor spreading is a process that occurs at mid-ocean ridges where new oceanic crust is formed and spreads apart. It is driven by the movement of tectonic plates, which are actually responsible for holding the seafloor in place.
Does new crust form at diverging tectonic plate?
Yes, new crust is formed at diverging tectonic plate boundaries through seafloor spreading. Here, magma rises to the surface, solidifies, and adds new crustal material to the plates. This process contributes to the continuous movement of tectonic plates and the Earth's geological activity.
How is seafloor spreading different than continental drift?
Seafloor spreading is the process where new oceanic crust is formed at mid-ocean ridges and then moves apart, while continental drift refers to the movement of continents on the Earth's surface. Seafloor spreading is one mechanism that helps drive the movement of continents as part of plate tectonics.
What states the youngest rocks of ocean floor are at a diverging boundaries moving outward?
The youngest rocks of ocean floor are found at mid-ocean ridges, which are diverging boundaries where tectonic plates move apart. As new oceanic crust is formed at these ridges through volcanic activity, it pushes the older rocks away from the boundary, making the ridge the youngest part of the ocean floor.
