Gradients are lowest in the central parts of continents, higher in the vicinity of . My bad for misunderstanding. For example, the eruptions of Mount Vesuvius that destroyed the nearby cities of Pompeii and Herculaneum represent rhyolitic lava flows. Yeah, I've spent a lot of time working with metals and baking out sand castings, lava temperatures are surprisingly low if you are used to those types of process temperatures. Tectonic plates form boundaries with one another at locations associated with zones of subduction and divergence. Volcanoes often form along both subduction and divergent plate boundaries. Basaltic lava is also referred to as mafic lava due to its low silica content and high iron oxide and magnesium content. These sodium and potassium carbonate minerals erupt as lava at relatively low temperatures (approximately 500-600 C) which is far lower than any other lava temperature on earth. Enrolling in a course lets you earn progress by passing quizzes and exams. At its surface (called the "photosphere") the sun's temperature is a whopping 10 000 F! It cools down as the eruption progresses. Use x to represent the temperature. Hood, and Mt. All rights reserved. Pahoehoe is low in viscosity and forms a smooth surface as the lava cools.
