Describe the chemical composition of magma
Like solid rock, magma is a mixture of minerals. It also contains small amounts of dissolved gases such as water vapor, carbon dioxide, and sulfur. The high temperatures and pressure under Earths crust keep magma in its fluid state. There are three basic types of magma: basaltic, andesitic, and rhyolitic, each … See more Magma is extremely hot liquid and semi-liquid rock located under Earths surface. Earth has a layered structure that consists of the inner core, outer core, mantle, and crust. Much of the … See more The viscosity (thickness) of the magma that erupts from a volcano affects the shape of the volcano. Volcanoes with steep slopes tend to form from very viscous magma, while flatter volcanoes form from magma … See more WebMagma is a mixture of liquid rock, crystals, and gas. Characterized by a wide range of chemical compositions, with high temperature, and properties of a liquid. Magmas are less dense than surrounding rocks, and will therefore move upward. If magma makes it to the surface it will erupt and later crystallize to form an extrusive or volcanic rock.
