What is an underground molten mixture of rock-forming substances gases and water from the mantle?

Mantle rock, usually fed by subducting crusts at destructive plate boundaries, melt under the heat, creating magma (or igneous melt). This magma is usually less dense than the surrounding (country) rock and so rises to or near the surface, forming igneous rocks in two ways:
1) The rock does not reach the surface, but cools and crystallises inside the Earth, creating INTRUSIVE igneous rocks. These usually have large crystals as they cool more slowly due to the hot surrounding temperatures.
2) The rock reaches the surface via volcanic or fissure eruptions as lava, and cools and crystallises very quickly on the earth's surface forming EXTRUSIVE igneous rocks. These have fine crystals due to the quick cooling time and colder surrounding temperatures.

∙ 9y agoIgneous rocks are formed from molten rock in the mantle. Molten rock, called magma, crystallizes as it cools forming different types of igneous rocks, depending on the rate of cooling.

What is molten mixture of rock forming substances gases and water from the mantle?
Magma
Magma forms when rocks begin to melt?
Yes. Magma is underground molten rock.
Where does heat that changing rocks into metamorphic rock come from?
The heat from the mantle and core.
What is the mantle mostly made up of?
The earth's mantle is not made of metal but is a mixture of many somewhat molten rocks, most as oxides, meaning the mantle may be more oxygen than metal. The metals it has the most of are magnesium, iron, and aluminum. There's also lots of silicon, which is not really a metal.
What are the 3 names of Mars' layers?
Mars's 3 layers are the crust, mantle, and core. Mars's crust is red and dust. Mars's mantle is made up of helium and rock substances. Mars's core is very hot. It is made up of iron.

Magma forms when rocks begin to melt?
Yes. Magma is underground molten rock.
What is an underground geothermal reservoir?
Over thousands of years rain water seeps through cracks in the Earth's crust and collects in underground reservoirs between the crust and the mantle. The mantle heats the water into a super-heated liquid and, voila!, you have a geothermal reservoir!
Do diamonds come from the earth's inner core?
Diamonds form under great pressure and heat in the mantle. The mantle surrounds the core. Diamonds are found in intrusive lava, (underground deposits)
Is most of the water on Earth underground?
If you count the water that is mixed in with the rock of the mantle, yes. Otherwise, no. Most of the water is in the ocean.
Where does heat that changing rocks into metamorphic rock come from?
The heat from the mantle and core.
What forms earth crust?
thickness 1/8( a mixture of lighter and heavier rocks which were forced out from the mantle by volcanic activity)
