In sea-floor spreading, molten material rises from the mantle and erupts at mid-ocean ridges. This process creates new oceanic crust as the magma cools and solidifies upon reaching the ocean floor. As tectonic plates move apart, the continuous addition of new material pushes older crust away from the ridge, contributing to the expansion of the ocean basin.

In seafloor spreading molten material rises from the mantle and erupts?
When spreading molten material rises from the mantle in the sea-floor and erupts, it can create sea mounts, which are underwater mountains. If enough material is ejected, the mounts will break through the surface of the water to create islands.
Where does molten material that rises from the mantle erupt?
it erupts from the mantle witch is part of the structure of the earth.
Does seafloor displaces more of the mantle that the same thickness of the continental crust?
Yes, the denser oceanic crust of the seafloor will displace more mantle material compared to the same thickness of continental crust due to its higher density. This is because the thicker, less dense continental crust floats higher on the mantle compared to the thinner, denser oceanic crust.
Does every volcano form in the mantle?
No, the Earth's mantle is to deep and warm for this. Magmas are generated in the upper mantle by a process called partial melting and the melt collects in the crust (in magma chambers at varying depth).
In sea floor spreading molten material rises from the mantle and erupts along what?
In sea floor spreading, molten material rises from the mantle and erupts along mid-ocean ridges. These underwater mountain ranges serve as the sites where tectonic plates diverge, allowing magma to flow up and solidify, creating new oceanic crust. As this process continues, it pushes older crust away from the ridge, gradually expanding the ocean floor.

When solid mantle rock rises during seafloor spreading magma is produced as a result of decompression melting?
Yes, during seafloor spreading, when solid mantle rock rises due to plate tectonic forces, it experiences reduced pressure which leads to decompression melting. This process produces magma that eventually erupts onto the seafloor, creating new oceanic crust.
What is the process that makes old oceanic crust go into the mantle?
makes up the bottom of the world's oceans is Magma from the underlying mantle erupts at the edges, then cools and solidifies to form new ocean crust.plate a process called seafloor spreading and back into the.
What is a constructive force caused by the convection in the mantle?
A constructive force caused by convection in the mantle is seafloor spreading. As hot mantle material rises and spreads out at mid-ocean ridges, it creates new oceanic crust, which pushes the older crust aside. This process helps in the formation of new oceanic crust and contributes to the widening of the seafloor.
Does seafloor displaces more of the mantle that the same thickness of the continental crust?
Yes, the denser oceanic crust of the seafloor will displace more mantle material compared to the same thickness of continental crust due to its higher density. This is because the thicker, less dense continental crust floats higher on the mantle compared to the thinner, denser oceanic crust.

What is the place were the seafloor if forced down into the mantle?
mid ocean ridge
What is Place were the seafloor is force down into the mantle?
mid ocean ridge
When a valcno erupts what happens in the earths core?
During a volcanic eruption, the molten material from the earth's mantle rises through the crust and erupts onto the surface. This process does not directly impact the earth's core, which is located much deeper beneath the mantle. The core is a solid inner layer of iron and nickel, primarily responsible for generating the earth's magnetic field.
What is a constructive force caused by the convection currents in the earth's mantle?
A constructive force caused by convection currents in the Earth's mantle is seafloor spreading. As hot mantle material rises at mid-ocean ridges, it spreads the seafloor apart, creating new oceanic crust. This process contributes to the formation of new ocean basins and drives the movement of Earth's tectonic plates.
