Webany property that produces a change in the composition of matter. If the viscosity is higher will it flow slowly or quickly? slower. If the temperature is hotter, would it make the … WebThe magma, called lava when molten rock erupts on the surface, cools and solidifies almost instantly when it is exposed to the relatively cool temperature of the atmosphere. Quick cooling means that mineral crystals don't have much time to grow, so these rocks have a very fine-grained or even glassy texture.

WebA body of molten rock found at depth, including any dissolved gases and crystals. igneous rocks. Rock formed from the crystallization of magma. lava. Magma that reaches Earth's … WebAs magma rises up through the crust, either by volcanic eruption or by more gradual processes, it cools and minerals crystallize. If the cooling process is rapid (minutes, hours, days, or years), the components of the minerals will not have time to become ordered and only small crystals can form before the rock becomes solid. breaking things autism

4.3: Magma Generation - Geosciences LibreTexts

WebMagma is created at mid-ocean ridges via decompression melting. Strong convection currents cause the solid asthenosphere to slowly flow beneath the lithosphere. The upper … WebThe viscosity of magma depends upon its Physical properties: 1. silica content. The major ingredient in magma is silica (50-70%), a compound made up of particles of the elements oxygen and silicon. The amount of silica in magma helps to determine its viscosity. The more silica magma contains, the higher its viscosity. Magma that is high in silica cost of issuing equity
