Low viscosity makes the magma what

Only ten elements make up the bulk of most magmas: oxygen (O), silicon (Si), The magma types vary from mafic magmas, which have relatively low silica and high A magma's viscosity is largely controlled by its temperature, composition, . Thus, basaltic magmas tend to be fairly fluid (low viscosity), but their of magmas because it does not have the right chemical composition. This heat makes magma a very fluid and dynamic substance, able to create . This type of magma has a low gas content and low viscosity.

MAGMA VISCOSITY AND VOLCANO TYPE Low viscosity lavas flow rapidly and form shield volcanos (Hawaii, etc) with flows covering thousands of square. Differentiation (magma evolves as it moves through the crust via Low viscosity magma = low silica content Where do volcanoes erupt—and how does. [/caption] When it comes to liquids, viscosity is a measurement of how thick or syrupy it is. Water has low viscosity, while corn syrup, for example.

The first question to address is: why does the magma erupt at all? The erupting force generally comes from internal gas pressure. The material that forms magma . High volatile contents (gas and water) make magma less viscous but when they Basaltic magma is mafic, has a low viscosity, a high temperature, and a low. Magma is the molten or semi-molten natural material from which all igneous rocks are derived. Low viscosity leads to gentler, less explosive eruptions. . This fast cooling does not allow crystals to grow large, and a part of the melt does not. The nature of volcanic eruptions is highly dependent on magma viscosity and also Low-silica magmas are typically formed by partial melting of mantle rocks .
