Magma in the mantle moves in a current called a convection current. A convection current is a circular flow of a substance in which a hot substance rises, cools, sinks, gets hot again, and repeats. In this way, magma in the mantle flows in currents of more hot or more cool magma.

Does the increase in silica increase the viscosity of a magma?
it is normally intermediate flow because of the silica content.
What happens when rising magma breaks through the earth's crust?
When magma comes in contact with water first the water will stem because the magma is so hot the water is at or past its boiling point them the magma will harden fast because instead of its slow cooling prossess it is spead up from the waters temperature it is a big mess :) luvhh jasmine chanda
Why does a non explosive eruption occur when basaltic magma is present?
The explosive potential of a volcano is determined by two primary factors:Gas within the magmaViscosity of the magmaThe combination of the gas and the viscosity determine the explosive potential of the magma as a result of the ability for the magma to flow as well as if it can release the dissolved gasses in a passive manner.Volcanoes that have a high concentration of Silica in their magma traditionally have a tendency to erupt more explosively. In the case of basalt, although there is traditionally a high level of dissolved gasses within the magma, basalt can easily flow. The ability for basalt to easily flow allows for the passive release of the gasses that are dissolved in the magma resulting in a non-explosive eruption as the gasses are released over time as the magma reaches the surface and not catastrophically as the magma escapes.
Why are volcanoes are commonly found at the edges of earth moving plates?
I don't know :( this is my assignment :P
Why does granitic magma cause explosive eruptions?
Granitic magma is highly viscous (resists flow). This high viscosity results in the entrapment and buildup of gases which create explosive eruptions.
What rock can flow like a liquid?
the rock that can flow like a liquid is a mantle because the mantle has two parts. The upper part is the solid rock. The solid rock of the mantle is part is the lithosphere. Below the solid rock, the mantle rock has the ability to flow like a liquid. Most of the mantle is made up of rock that can flow. Sanjida Ahmed 752/753
What caused the eyjallajokull eruption?
Volcanoes erupt because of the flow of magma in the mantle, which reaches the surface.
What part of the mantle can flow like thick liquid?
The outer core of the mantle can be liquid.
What is the plasticity of the mantle?
It is the ability of the mantle (solid) to flow like liquid.
Which part of the earth's mantle can flow like a thick liquid?
no part
What part of the mantle can flow like a liquid?
None! Unless you mean the core. The outer core is liquid.
What part of mantle can flow like a thick liquid?
None! Unless you mean the core. The outer core is liquid.
What part of the mantle can flow like a thick liquid?
None! Unless you mean the core. The outer core is liquid.
What is the state of matter in the upper mantle?
solid
How does heat flow in the mantle?
My guess: its almost like boiled water. you know how the steam rises? same with the heat from the magma in the mantle. The magma itself is around 500-900 degrees celcius, so the heat is much less by the time it makes it to the surface of the earth. that is my guess
What is the Solid layer of earth that can flow because of great heat and pressure?
The mantle is the solid layer of earth that can flow because of great heat and pressure
What areas seem to have many volcanoes?
Areas where continents are either moving apart or together causing magma from the mantle to flow to the surface
