Once a meteorite has been analyzed and classified by academia, surplus specimens find their way onto the commercial market. The process of acceptance into the official scientific literature actually adds commercial value to a meteorite. Meteorite prices vary from one source to another but the numbers...
Volcanoes are classified as dormant, active, and extinct. One of the most active volcanoes today is in Mauna Loa, Hawaii. Is it magma or lava? Well, it’s both! Magma is the liquid rock inside the volcano, and once it spills out of it, it is called lava. Lava will burn everything...
Magma is classified based on its silica content, which influences its viscosity, temperature, and eruptive behavior. The four primary types of magma are: Types of magma: mafic, intermediate, and felsic, showcasing their composition, silica content, viscosity, and associated volcanic activity. ...
Yet as destructive as volcanoes can be, they pale in comparison to supervolcanoes — colossal geothermal formations capable of ejecting over 240 cubic miles of material in a single eruption. To be classified as a supervolcano, an eruption must register at level 8 on the Volcanic Explosivity Inde...
