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.

What is liquid rock?
Ah, liquid rock is a fascinating thing, my friend. It's just like when you're painting with warm, flowing colors on your canvas. When rock deep beneath the Earth's surface gets so hot that it melts, it turns into liquid rock, also known as magma. This magma can eventually make its way to the surface and flow out as lava, creating beautiful landscapes and new land for all of us to enjoy.
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
What can flow if the upper mantle?
Magma can flow if the upper mantle, leading to volcanic activity on the Earth's surface.
What caused the eyjallajokull eruption?
Volcanoes erupt because of the flow of magma in the mantle, which reaches the surface.
What rock can flow like a liquid?
A rock that can flow like a liquid is called a type of rock called "viscous rock," such as granite or basalt. These rocks exhibit a plastic-like behavior at high temperatures and pressures, allowing them to flow over long periods of time. This flow is known as creep.
What part of the mantle can flow like thick liquid?
The outer core of the mantle can be liquid.
Why doesn't the lava in the mantle harden?
The lava in the mantle does not harden because it is under high pressure from the overlying rock layers and is constantly being heated by the Earth's core. This keeps the mantle rocks in a semi-solid state known as magma, which can flow slowly over long periods of time.
What process causes liquid rock to move?
Liquid rock, or magma, moves through the process of convection within the Earth's mantle. Heat from the Earth's core causes magma to become less dense and rise towards the surface, while cooler, denser material sinks back down. This circular movement of hot magma is what propels the flow and movement of liquid rock beneath the Earth's surface.
What part of the mantle can flow like a liquid?
None! Unless you mean the core. The outer core is liquid.
Why is the mantle not a runny liquid but a thick paste?
The mantle is a semi-solid layer made up of hot, flowing rock known as magma that circulates slowly over geologic time scales. While it appears solid, the mantle can still flow and deform over long periods due to high temperatures and pressures. This behavior gives it a paste-like consistency rather than a runny liquid.
What part of mantle can flow like a thick liquid?
None! Unless you mean the core. The outer core is liquid.
Why do scientists think that the mantle is semi soild and acts like a liquid?
Scientists think that the mantle is semi-solid and acts like a liquid because of its ability to flow slowly over long periods of time. This behavior is called plastic deformation, which allows the mantle to flow in response to stress and heat. The mantle's semi-solid nature is also supported by seismic data and laboratory experiments on rock samples.
Is the mantle a soild or liquid?
The mantle is mostly solid, but it can flow slowly over long periods of time, behaving like a very viscous liquid. This movement is what drives plate tectonics on Earth.
Why isn't the Earth's entire mantle liquid?
The Earth's mantle is not entirely liquid because the temperature and pressure conditions vary throughout the mantle. While the high temperatures in the lower mantle can cause some rock to partially melt and flow, the majority of the mantle remains solid due to the higher pressure that prevents complete melting.
