The process that causes liquid rock to move is called magma migration. This movement occurs due to changes in temperature and pressure within the Earth's crust, which can lead to the rise of molten rock towards the surface, eventually forming volcanoes when it erupts.
The movement of liquid rock in the asthenosphere is mainly driven by convection currents, a process where hot rock rises, cools, and then sinks back down. This flow is due to the heat generated by the Earth's core, causing the asthenosphere to slowly move and deform over time.
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.
The tectonic plates move because of the great amount of liquid rock, or magma that they 'float' on and get pushed by.
As liquid rock cools down, its particles lose energy and move closer together, forming solid crystals. This process is known as crystallization. The specific minerals that form depend on the composition of the original liquid rock and the cooling rate.
The rock formed by cooling a liquid rock after processing is called a crystal.
The process of melting transforms gneiss, a metamorphic rock, into magma by subjecting it to high temperatures and pressure deep within the Earth's crust. This causes the minerals in the gneiss to melt and form a molten liquid called magma.
Sediment and rock move to lower elevations primarily due to the force of gravity acting on them. This process, known as erosion, is facilitated by various agents such as water, wind, ice, and gravity itself. Over time, the movement of sediment and rock contributes to the formation of landforms and reshapes the Earth's surface.

The high temperature of liquid rock reduces its viscosity, allowing it to flow more easily. This low viscosity is due to the rock being in a molten state, which reduces the resistance to flow. Additionally, pressure from volcanic activity can also contribute to the movement of liquid rock.
This fits the description of a metamorphic rock.
The earth is made mostly of rock. Deep under the surface this rock is still hot after the creation of the planet. This heat causes the rock to be 'liquid' (although it's very very thick and flows very slowly) The heat also causes the rock to churn like hot water in a pan. (a process called 'mantle convection' Where the earth's crust is thin, the churning can force the rock through cracks in the crust, resulting in a volcano. When this happens, the drop in pressure can allow the hot rock to become truly liquid, this is the lava/molten rock we see flowing down the side of volcanoes.
