it cool quickly but i dont know know how. i have a science homework do tomarrow and i know it cools quickly, but another question is how do you know. i cant just right that i googled it!!!! HELP
Yes the Obsidian does cool quickly and the vesicular basalt
Obsidian cooled very quickly. It's a vulcanic glass, meaning that the crystals are so small, they had virtually no time to form an orderly crystalline texture, and are basically placed randomly. Smaller grain size is associated with faster cooling.

If you are asking about how they were formed magma from volcano that are shot in the air of quickly spewed out causing the magma to cool very quickly forming a very smooth surface on obsidian. Becuase the magma cooled so fast it couldn't slowly cool into a rough textured rock.
yes
The thermal conductivity and color of a surface determines how quickly or slowly it will heat and cool
They cool to quickly for crystals to form.
