The main mechanism for melting at spreading ridges is decompression melting. As tectonic plates diverge at these ridges, the mantle material rises to fill the gap. This rise reduces the pressure on the mantle rocks, causing them to melt and form magma. The resulting magma then contributes to the formation of new oceanic crust as it erupts and solidifies at the surface.

Is the main mechanism for melting decompression melting of ultramafic mantle rock?
Yes, the main mechanism for melting in decompression melting involves ultramafic mantle rock. As tectonic plates move apart, the pressure on the mantle rock decreases, allowing it to melt at higher temperatures. This process is primarily responsible for the generation of magma at mid-ocean ridges and other divergent boundaries. The resulting melt is typically basaltic in composition, originating from the ultramafic materials found in the upper mantle.
Which forms at mid-ocean ridges?
New oceanic crust is created along mid ocean ridges. These are areas of the earth where there is divergence or splitting of the ocean floor and basaltic magma oozes out from within the mantle to occupy the gaps and form new crusts.
What are the two main causes for Harry Hess' mid ocean ridge?
The two main causes for Harry Hess' mid-ocean ridge hypothesis are seafloor spreading and plate tectonics. Seafloor spreading is the process where new oceanic crust is formed at mid-ocean ridges, pushing older crust away. Plate tectonics is the theory that Earth's lithosphere is divided into large plates that move and interact with each other, resulting in geological phenomena like seafloor spreading.
What are the main features of a zone of Divergence?
well that's easy just look up on divergent boundaries and it states the main features,which are two tectonic plates,ocean plates and mid-oceanic ridges.
What models have been propose to explain the driving mechanism for plate motion?
Two main models have been proposed to explain the driving mechanism for plate motion: slab pull and ridge push. Slab pull suggests that the gravitational force acting on a denser oceanic plate sinking into the mantle pulls the rest of the plate along with it. Ridge push, on the other hand, suggests that the elevation difference between the elevated mid-ocean ridges and the lower trenches exerts a gravitational force that pushes the plates away from the ridges.

What was the problem with the theory of sea floor spreading?
The main problem with the theory of sea floor spreading was initially the lack of a known mechanism for how it could occur. Additionally, there was skepticism about the idea of continents moving because it challenged long-standing beliefs about the permanence of Earth's surface features. The theory faced criticism until the discovery of plate tectonics provided a mechanism to explain sea floor spreading and continental drift.
What are the main cells in the human kidney?
mechanism of main cells in a kidney?
What is the main mechanism for diluting blood?

What material is a natural Fire retardant ?
There are two main types of fire retardant material that are used in clothing. Those materials are nomex and cotton. These materials prevent the fire from spreading or melting, so once the material is burned up the fire dies.
What is the huge underwater mountain ranges that are presented in every ocean and circled earth?
The underwater mountain ranges that are present in every ocean and encircle the Earth are called mid-ocean ridges. These ridges are formed by tectonic plates spreading apart, creating new oceanic crust. They are home to unique ecosystems and diverse marine life.
What is the main concern of athletes competing at commonwealth games?
The two main concerns are Dengu fever spreading, and terrorism.
