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.

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.
During seafloor spreading most volcanic magma is produced at?
During seafloor spreading, most volcanic magma is produced at mid-ocean ridges, where tectonic plates are diverging. As the plates separate, magma from the mantle rises to fill the gap, creating new oceanic crust. This process results in volcanic activity, forming underwater volcanoes and contributing to the growth of the ocean floor. The continuous cycle of magma generation and solidification at these ridges is a key mechanism in plate tectonics.
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.
How does magma help seafloor spreading?
Magma plays a crucial role in seafloor spreading as it rises from the mantle at mid-ocean ridges, where tectonic plates are diverging. When magma reaches the ocean floor, it cools and solidifies, forming new oceanic crust. This process not only creates new seafloor but also pushes older crust away from the ridge, facilitating the movement of tectonic plates. As a result, seafloor spreading continuously reshapes the ocean floor and contributes to geological activity.
What Magma is released creating new seafloor at boundaries?
At mid-ocean ridges, magma is released from the mantle as tectonic plates diverge, creating new seafloor through a process known as seafloor spreading. This magma, primarily basaltic in composition, rises to fill the gap between the diverging plates, solidifying to form new oceanic crust. As the magma cools and solidifies, it contributes to the formation of new seafloor, which is continually created and pushed away from the ridge by the movement of tectonic plates.
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.
