Volcanic eruptions

Red lava rock is available in nature and is formed from volcanic eruptions. Volcanic rocks are composed of oxides of diverse metals and have considerable porosity. In this study, lava rock powder was ground to a specific size and dried to test its ability to adsorb heavy metals in water. The morphology of the stone powder was observed to show crystals of 100–300 nm in size clumping into particles of a few μm.

Volcanic eruptions are among the Earth's most powerful and destructive forces. Imagine hearing a volcano erupt thousands of miles away. Imagine looking through binoculars and seeing the top of a mountain collapse. Imagine discovering an ancient Roman city that had been buried in volcanic ash. Volcanoes are also creative forces. The Earth's first oceans and atmosphere formed from the gases given off by volcanoes. In turn, oceans and an atmosphere created the environment that made life possible on our planet. Volcanoes have also shaped the Earth's landscape.
