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 else can I help you with?
How Convection currents in the Earth and mantle are responsible for the movement of tectonic plates. As shown in the diagram heat from the Earth and core is the driving force that moves magma in a?
Convection currents in the Earth's mantle are driven by the heat from the Earth's core, causing magma to rise and cool, then sink as it loses heat. This continuous cycle creates a flow that exerts force on the tectonic plates above. As the magma moves, it drags the plates along with it, leading to their movement. This process is fundamental to the dynamics of plate tectonics, resulting in phenomena such as earthquakes and volcanic activity.
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.
What caused the eyjallajokull eruption?
Volcanoes erupt because of the flow of magma in the mantle, which reaches the surface.
What can flow if the upper mantle?
Magma can flow if the upper mantle, leading to volcanic activity on the Earth's surface.
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 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?
Lava is the mantle is called magma. Lava, referring to magma that is flowed out onto Earth's surface, only hardens when the temperature around it drops. This is because lava is very hot, and when the temperature drops, it cools and solidifies due to its thixotropic and shear thinning properties, just like clay. Magma is actually kept in its liquid state because of the temperature of the mantle, which ranges from 500°C to 4,000°C. The magma itself in the mantle is approximately 700°C to 1300°C, which means that the temperature is not low enough for magma to harden. Magma is part of the convection process occurring inside the mantle. Since the mantle closer to the core is of higher temperature than when closer to the crust, there is a convection process where magma heats up from the hotter core side and rises to the cooler crust side and vice-versa. Thus, just like when you keep mixing clay, the moving magma in the mantle will not harden.
What process causes liquid rock to move?
Vulcanism is the process that forces liquid rock (magma) from deep within the Earth, up to the surface. Once the rock is expelled from a Volcano, the force of Gravity makes it flow down the sloped 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.
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.
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.
