Obsidian Little Common Sense
The formation of obsidian was about 34 million years ago. At that time, huge meteorites hit the earth. During the meteorite impact on the earth, most of the meteorites entered the earth at a speed of 11-74 km per second through the atmosphere. During this process, friction with the Earth's atmosphere caused the surface to melt due to the heat. After the unburned residue has fallen to the ground, it is obsidian.
