Which process in the rock cycle causes magma to form?
Melting is the process in the rock cycle that causes magma to form.
What process causes rocks to crack?
heat and extreme pressure. also water freezing and melting.
What causes the asthenosphere to be molten?
radio active decay
Describe how the presence of ocean water in crustal rocks might affect the formation of magma?
Since "Wet" rock melts at a lower temperature than "dry" rock, this helps initiate partial melting in subduction zones. The subducting material is saturated with sea water which helps speed up the melting process. Steam rises into the overlying lithosphere and asthenosphere and causes the formation of vast quantities of magma
What role does asthenosphere play in generating magma at a convergent boundary?
At an oceanic subduction zone, the athenosphere is subducted under continental lithosphere, or under other oceanic lithosphere. Friction between these plates causes heat that creates magmas. At a divergent boundary upwelling mantle (athenosphere) decompresses due to reduced pressures, allowing magma to form. This magma is extruded onto the seafloor as pillow basalts, and beneath the seafloors as massive gabbros and sheeted (gabbro) dikes.
How does the process of convection affect the asthenosphere?
This such an easy question...It causes the asthenosphere to move and push against the pieces of the lithosphere... luv,,,Autumn m.
Which process in the rock cycle causes magma to form?
Melting is the process in the rock cycle that causes magma to form.
What are the sources of heating that are responsible for the generation of Earth's magma?
Much of the heat is generated by the intense gravitational pressures caused by the surface depth and the intense friction created in the subduction zone, but there also a great deal of secondary factors. With the introduction of water in the subduction zone due to the fact that "wet" rock melts at lower temperatures than "dry" rock and aids in the process of partial melting in the subduction zones. The subducting material that is saturated with sea water mixes with the material and speeds the melting process. Steam rises into the overlying lithosphere and asthenosphere and causes the formation of vast quantities of magma due to pressure relief melting.
What process causes rocks to crack?
heat and extreme pressure. also water freezing and melting.
What are the main causes of convection in the asthenosphere?
Density and tempurature.
What causes the asthenosphere to be molten?
radio active decay

What causes the convection currents in the asthenosphere?
The convection currents running through the asthenosphere are widely believed to be the source of movement of the tectonic plates.
What is generation gape in human being?
what is generation gape ,its causes and its solutions? what is generation gape ,its causes and its solutions?
Interaction between which two regions causes plate movement?
The lithosphere and the asthenosphere.
If the process of melting absorbs heat energy from the surroundings then what would the process of freezing do?
Melting is the result of enough heat energy being transferred INTO an object to turn it into a liquid. Freezing is the result of enough heat energy being transferred OUT of a liquid to turn it into a solid. Melting and freezing are not as much of a "process" as they are a result. For example: When you put water into the freezer, the heat energy in the warm water is transferred into the colder air, which causes the water to freeze. That process causes the air in the freezer to warm up slighltly. The process of refridgeration then transfers that heat out of the freezer, which makes the air in the freezer nice and cold again.
