What affects the melting temperature of magma? What is magma made of? What effect does temperature have on the characteristics of magma? What prevents rocks in the mantle from melting? What forms when magma cools? What determines the viscosity of magma?
What is the criterion of deciding whether the liquid has low, medium or high viscosity? Byanon3625— On Sep 08, 2007 but why are some liquids more viscous than others is it because they have different solidifying points? or is it their atoms being closer. Or something completely different...
Understand the methods of measuring the viscosity of a fluid. Related to this QuestionWhat is the effect of temperature on the viscosity of a liquid? How do you define viscosity? What is viscosity? Define the viscosity. Which of the following are ways that viscosity affects gases in magma? (...
What is viscous lava? Question: What is viscous lava? Volcano and Magma: A volcano is the forcible ejection of the hot molten rock materials and gases found beneath the surface of the earth. The molten material is the magma, and once it reaches the surface, it loses its heat and gases,...
The brittle rocks that make up Earth's tectonic plates are the lightest part, floating as they do on a thick layer of magma. But those tectonic plates (the lithosphere) cooled from the molten rock below: specifically, from a ductile, low-viscosity, silicon-rich, and tectonically "slippery"...
catastrophically. since low-viscosity magma is typically low in silica, shield volcanoes are more common in oceanic than continental settings. the hawaiian volcanic chain is a series of shield cones, and they are common in iceland, as well. read more: shield volcano lava domes lava domes are ...
Analyses of the lunar rocks revealed a high-temperature ( approximately 1400 degrees C), low-viscosity (<10 Pa s) basaltic lava; martian meteorites also have a mafic to ultramafic compositions. These results have been used repeatedly to infer similar compositions on other terrestrial planets on ...
Is Basalt made of lava? Basalt is themost common composition of lava rocksthat cool from magma, liquid rock that rises from the deep Earth at volcanoes. What two minerals are in Basalt? Basalt is mainly made of two minerals:Plagioclase feldspar and pyroxene. ...
What is Viscosity? Discussion Comments Byanon993755— On Dec 11, 2015 In what year was the theory of plate tectonics developed? Byanon301898— On Nov 06, 2012 How do they move? Byanon270699— On May 23, 2012 Why is it not possible to search one famous volcano located between the differ...
Inter-oceanic hotspots form under oceanic plates. The magma that is formed in these magma chambers is basaltic in nature, having a low viscosity and low water content. This type of magma primarily produces very fluid lava flows. Pressure does not tend to build up in inter-oceanic magma chambe...
