Well there are Different levels of viscosity of magma in the earth's crust, you just got to know where the magma is according to the tectonic plates.

We know what the magma is like under the earth by studying Volcanoes and how they erupt and how the magma flows. The majority of Stratovolcano's or Composite Volcano's; (The tall explosive ones like MT. ST Helen's) usually explode and have dormant periods because of the plate boundary that they sit on.

On a Subduction zone the ocean plate is force under the lighter continental plate. But with it ocean water that has been trapped in the rocks alongside allot of Limestone melt in the mantel. Releasing allot of gases, which under the immense pressure of the earth dissolve in the semi molten rock, this makes it very thick and slow to move. Hence Stratovolcano, further up.

But you also get runny water like rock that isn't very viscous at all, in fact you can safely stand 100M away from it! or even out WALK it! You can find this at Hawaii out of Mt. Kilauea. The magma is like this because Hawaii sits on a Hot spot.

What is the change of state when magma crystallizes from igneous rock?

Your question as phrased is unclear. I will proceed to answer both interpretations I have of your question. Note: When magma crystallizes, it forms igneous rocks. 1) What is the change of state when magma forms from igneous rock? - Melting. Rocks are the solid state of matter and magma is the liquid state (although it can be a very viscous liquid). Changing something from solid to liquid is melting. 2) What is the change of state when magma crystallizes to form igneous rocks? - Solidification/Freezing. Magma becomes too cold to continue in a liquid state, it solidifies and crystallizes into solid igneous rocks: freezing.


What word describes rock in its liquid state?

Magma.


What is the solvent in magma?

There is no solvent in magma. Rocks turn to a liquid state because of super-heating, not because the solids were dissolved in any solvent.


When the force of magma pushing upwards is equal to the force of the rock pushing downwards the system is said to be on a state of what?

When the force of magma pushing upwards equals the force of the rock pushing downwards, the system is said to be in a state of equilibrium. This balance prevents the magma from continuing to rise or the rock from collapsing further.


If Ice is to water than Rock is to?

Lava or Magma is rock in its molten state.


The liquid state of a rock whenheated to a high temperature?

Magma, if underground, and Lava, if above the ground


How are volcanoes and magma related?

Magma is the molten material beneath the surface (crust) of the earth. Magma is called lava when it emerges from the earth in its molten state. The volcano is the geologic structure at the end of a volcanic chimney, which is the duct that connects the magma pocket in the earth through the crust to the surface. The volcano is actually at the "output end" of that volcanic tube.


How does magma rock form?

When the magma cools it hardens, turning from sort of a liquid into a solid. Just like if you melted cheese it would eventually harden back to its regular solid state.


Is super cooled magma is a state of matter?

Supercooled magma is not a state of matter itself, but rather a term used to describe magma that has cooled below its usual crystallization temperature. It is still considered a liquid state of matter, but in a highly viscous and partially solidified form.


What magma is silica-rich thick magma?

An acid magma or a granitic magma.


What are the changes of the state that happens when metamorphic rock changes into magma?

Solids become liquids. A phase change.


What is the definition of magma in science?

Magma is molten rock beneath the Earth's surface that can sometimes rise to the surface through volcanic activity. It consists of a mixture of liquid rock, crystals, and dissolved gases. As magma cools and solidifies, it forms igneous rocks.
