Igneous rocks with very small or no visible crystals are formed by rapid cooling. A good example would be obsidian (which is a volcanic glass) and BAsalt which may have an aphanitic texture (crystals to small to see with the naked eye).

What is rock formed from cooled magma or lava?
Is called igneous rock.
What is the structure of an igneous rock?
the structure of an igneous rock is metamorphic rock that has been heated rapidly and turned into magma then cooled to create igneous rock its gay
An igneous rock cooled very rapidly as it was formed because it was exposed to air What type of rock could it be?
it is an extrusive rock
What type of rock is formed when an igneous rock is cooled very rapidly?
When magma is cooled, it forms an igneous rock. When magma is cooled rapidly, that igneous rock is of the category called "extrusive" or "volcanic". When the magma is cooled very rapidly, the extrusive igneous rock formed will probably be holohyaline (glassy) in texture, or foamy like pumice.However if you take an igneous rock that is already rock and cool that very rapidly it will probably shatter owing to thermal stress. That might result in the formation of tuff.

How an igneous rock formed?
Igneous rock is formed from lava that has cooled and, of course, hardened.
