A carbon-rich solid material derived primarily from coal.
Coke, in the context of fuel and metallurgy, is a carbon-rich solid material derived primarily from coal and used chiefly in iron and steel production. It is created by heating bituminous coal to high temperatures in the absence of air, a process known as destructive distillation or carbonization. This heating drives off volatile substances such as gases, tars, and oils, leaving behind a porous, nearly pure form of carbon. The resulting product is hard, gray, and lightweight relative to its
Mystery at Blind Frog Ranch (Discovery Channel) visited the Serpent Mound in Ohio and were shown shatter cones from the meteorite impact that happened there.
Shatter cones are distinctive geological features that serve as compelling evidence of hypervelocity impact events, such as those caused by meteorites. They are cone-shaped, striated rock structures formed under extremely high pressures, typically exceeding 2 GPa (gigapascals), in the moments following an impact.
