Magma can form at varying depths in the Earth, typically from about 30 kilometers to over 150 kilometers beneath the surface. The exact depth at which magma forms depends on several factors, including the composition of the mantle rocks and the presence of fluids or volatiles that can lower the melting point of rocks.

What is the molten material deep inside Earth which forms igneous rock?
The molten material deep inside Earth is called magma. When magma cools and solidifies, it forms igneous rock.
What type of crystals form when magma cools very slowly deep beneath the Earth's surface?
Intrusive igneous rocks like granite form when magma cools slowly deep beneath the Earth's surface. This slow cooling allows large mineral crystals to grow, resulting in a coarse-grained texture.
Which type of rock can form deep below Earth's surface or above Earth's surface?
Igneous rock can form deep below the surface as intrusive igneous rock, or on or near the surface as extrusive igneous rock. X Answer is: Igneous
Does granite form from magma?
Yes, granite forms from the slow cooling and solidification of magma deep within the Earth's crust. As the magma cools, minerals such as quartz, feldspar, and mica crystallize and combine to form granite. This process typically occurs over millions of years.
Granite is an example It forms deep underground It needs heat to form What is it?
Granite is an igneous rock that forms deep underground from the cooling of molten magma. It requires heat and pressure to form, typically found in the Earth's crust.
