Is magma a solid? How does magma become lava? What is the difference between magma and lava? Is magma a liquid? Does a composite volcano have mafic or felsic lava? Is magma a mineral? Is the mantle made of magma? How hot is the magma chamber in a volcano?
What is liquid magma that flows from a volcanic vent called? Volcanic Eruptions: Volcanic eruptions occur because of a buildup of pressure beneath the Earth's surface. While some eruptions are violent and potentially devastating other eruptions can occur over the course of many years or decades...

Is the inside of the Earth mostly solid or liquid? The Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball, about 1,500 miles (2,400 kilometers) in di...
The mantle is made up of solid rock that can flow very slowly over long periods of time.The core is the innermost layer of the Earth. It is divided into two parts: the outer core and the inner core. The outer core is liquid and mainly composed of iron and nickel. The inner core ...
Silicon is also used in liquid solutions of calcium or sodium silicate, the latter of which is an alchemical brew also known as liquid glass or "waterglass." Liquid glass is unique for its near-eldritch ability to crystallize whatever it touches. It's the crystal-forming reagent in a lot ...
They sent waves under Yellowstone and measured how they bounced back, and it turns out that there simply is not enough magma down there for some big eruption in the foreseeable future. Plenty of the rock down there is hot but solid (rock solid, you might say). Meanwhile, even the parts...
Mercury is a liquid at room temperature, but when cooled to -38.8 degrees C, it crystallizes into a solid. Solid mercury meets all of the requirements of a mineral, and thus some people consider liquid mercury to be a mineraloid. Photo copyright iStockphoto / ados. Limonite is an ...
The geology of the Earth's surface is continually being shaped by volcanic activity. This natural process begins deep beneath the crust, when superheated magma (a liquid rock material made up of minerals and gases) rises toward the surface and erupts through cracks or vents. The molten rock re...
Geologists classify magma, the liquid rock below the surface of the Earth, by its chemical and mineral composition. All magma contains silicate minerals, but the amount of these minerals in relation to other minerals defines magma as mafic or felsic. Felsic magma has a high percentage of silica...
