Obsidian is formed from very rapidly cooling lava.
Obsidian is formed and cooled so rapidly from lava that it is a glass, not crystalline in structure. The cooling is obviously very rapid and solidification could probably measured in minutes.

Slowly
if a fast and expecive car yes.But a slow and ugly car no.

Granite does not directly transform into obsidian. Obsidian is formed when lava cools very quickly, without giving crystals a chance to form. Granite, on the other hand, forms deep beneath the Earth's surface through the slow cooling and solidification of magma. So, while both are igneous rocks, they form under different conditions.

Cool water moves slow because the molecules are moving slow. In hot water, molecules are moving fast, thus, hot water seems to move faster than cold water at times.
Obsidian are volcanic Glasses that cool very rapidly. The crystals are not allow to arrange them self's that is why Obsidian has not 3d internal structure. The are Igneous Glasses
Obsidian cools relatively quickly compared to other types of volcanic glass due to its composition and the rapid cooling process during its formation. The rate of cooling affects the crystal structure and appearance of the obsidian, leading to its characteristic smooth and glassy texture.
not a fast but slow
cool rapidly
