Lava that cools quickly forms extrusive igneous rock.
If lava cools so quickly that ions don't have time to arrange themselves into crystals, the resulting igneous rocks will form glass.
Lava that cools quickly forms extrusive igneous rocks. They are characterised by microscopic rather than large mineral crystals and are therefore smooth in appearance.
When lava cools quickly the minerals within it form rocks and crystals. These are the types of rocks which are commonly referred to as igneous rocks.
Yes because the crystals do not have enough time to grow.
Extrusive igneous rock.
It forms into a rock.
As molten rock cools and solidifies the chemical components arrange into organized structures on the molecular level. These are crystals.
Since basalt is extrusive it cools quickly and forms small crystals.
No. Small crystals form.
its not really a question...
When the liquid evaporates quickly, the solid crystals formed don't have enough time to arrange themselves into large crystals. On the other hand, when it evaporates slowly, the solid has lots of time so large crystals form. This can be demonstrated by dripping melted was onto a cold slide and a warm slide and examining them under a microscope.
IF the magma cools slowly witin Earths eated interior the atoms have time 2 arrange themselves into large crystals!
In some cases the molten rock cools too quickly for the atoms to arrange themselves into a crystalline structure.
False: they do have time 2 for large crystals 2 be made
glassy texture
False they have all the time in the wrold to form

Mostly, it depends on cooling time. If a rock cools very rapidly, a smooth texture is formed as the atoms quickly arrange themselves into a fairly smooth crystalline pattern. Think of obsidian; it cools very fast and has such small crystals looks like black warped glass. However, if a rock was formed below the Earth's surface (intrusively) like in a pluton, it will cool more slowly and will be rougher and have larger crystals.
Andesite has small crystals because it cools quickly.
fast cooling lava -small crystals or no crystals
fast cooling lava -small crystals or no crystals
If lava cools quickly, the minerals don't have as much time to form crystals, so the crystals do not become very large. Igneous rocks that cooled quickly and have small crystals are described as "aphanitic" igneous rocks.
