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.
Layers of thin runny lava that flow over a wide area before they cool and harden can build up lava plateaus or volcanic fields.
lava in the mantle
It has to harden
cause it will keep going until the lava stop erupting will make the mantle stop
Both pillow lava and pahoehoe lava are types of basaltic lava that form during submarine volcanic eruptions. They both have smooth, ropy surfaces, caused by the flow of lava, and are relatively low in viscosity.
Actually, it does not. It is soft.
Lava
lava
the earth's mantle is full of lava so the lava is what makes it so hot
the mantle is made of hot lava with rocks and pee
they dont; the lava comes from the mantle in the earth
it is kaka shamucky
it turs to rock
It is called Lava
volcanoes will erupt and let out lava then the lava will harden and that will be new land.
Because it cools down and changes its state of mater.
lava helps harden with stone and minerals grow it
