What else can I help you with?
What kind of rock forms when hot molten rock cools deep under the surface of the earth?
These are igneous rocks.
Is molten rock only found close to the surface?
No, it is found near the surface and even far bellow the surface.
What is the complete predicate in volcanoes are places on the earths surface where molten rock gases and ash from deep inside the earth are ejected?
"are places on the earth's surface where molten rock, gases, and ash from deep inside the earth are ejected."
Magma is molten material that forms .?
Magma is molten material that when cooled forms a solid called igneous rock
The tectonic plates float on what layer of earth?
The earth's tectonic plates are said to "float" on layers of magma, which is molten, or very hot liquid rock deep under the surface of theearth.
In brief how does a volcano form?
A volcan form when molten magma, formed deep in the Earth, makes its way to the surface.
What are plumes of molten rock originating deep within the mantle known as?
Plumes of molten rock originating deep within the mantle are known as mantle plumes. These plumes are believed to be responsible for hotspots and volcanic activity at the Earth's surface.
What is the name of the rock that churns deep beneath the earths surface?
The rock that churns deep beneath the Earth's surface is called "magma." It is a molten rock material that is located beneath the Earth's crust and can eventually rise to the surface as lava through volcanic eruptions.
Why do metamorphic rocks often formed deep under the surface of the earth?
Metamorphic rocks are often found deep under the earth's surface because metamorphic rocks form from heat and pressure. Therefore, they form while they are under the earth's surface.
Why does magma deep underground stay liquid longer than lava on the surface?
Magma is heated to its molten state via heat from the Earth's core and that heat is held in by the earths crust. Once on the surface there is nothing to keep it molten and is it cooled by the outside air.
Where are magma chambers located?
A magma chamber is a large underground pool of molten rock found beneath the surface of the Earth. The molten rock in such a chamber is under great pressure, and given enough time, that pressure can gradually fracture the rock around it creating outlets for the magma. If it finds a way to the surface, then the result will be a volcanic eruption; consequently many volcanoes are situated over magma chambers. Magma chambers are hard to detect, and most of the known ones are therefore close to the surface of the Earth, commonly between 1 km and 10 km under the surface. In geological terms this is extremely close to the surface, although in human terms it is considerably deep underground.
Describe two igneous structures that form under earths surface?
Igneous rocks are formed from the molten liquid minerals that lie below the earth's crust. Intrusive igneous rocks forms in magma chambers that are deep underground it is molten by heat and pressure. Extrusive igneous rocks forms when magma makes its way to Earth's surface when the molten rock erupts.Jennifer
