Granite could become extrusive by becoming molten and then erupted onto the surface. It will then become extrusive in that it formed at or near the surface from molten material.
Granite is already an igneous rock. If the granite simply melts and re-solidifies it will become granite again. If it melts and is erupted from a volcano, it will form rhyolite. If it melts and mixes with magma of a different composition, then it could form any number of igneous rocks.
The igneous rock most likely described is granite, which is composed predominantly of mica (specifically muscovite or biotite), feldspar, and quartz. This rock type forms from the cooling and crystallization of molten magma deep within the Earth's crust.
No, granite is a coarse-grained igneous rock that is made up of minerals like quartz, feldspar, and mica. Glassy igneous rocks, like obsidian, form when molten lava cools quickly on the surface, resulting in a smooth, glass-like texture.
No, but pumice can.
It could be Granite.
It could be Granite.
Could be basalt, an extrusive igneous rock.
Intrusive rock normally has visible crystals. Extrusive igneous rock has small crystals. A black extrusive igneous rock with small crystals could be basalt.
it is an extrusive rock
Granite is a form of 'igneous' rock... The name 'igneous' is taken from the Latin 'ignis', for 'fire', because igneous rock is formed from magma and volcanic activity.In short, while granite could be too hot for your cooking pots to handle, your cooking pots won't ever get too hot for granite to handle... They'd melt first! :-)
The igneous rocks formed when melted rock cools on the surface of the Earth are called volcanic or extrusive rocks. These rocks cool quickly, resulting in small mineral grains and a fine-grained texture. Common examples include basalt and rhyolite.
Granite is a type of igneous rock. At room temperature it would be a solid. The term igneous refers to rocks that have cooled and solidified from lava or magma. At one point the molecules that formed the granite were in a liquid state and given a hot enough temperature could form a gas.
