We have a new and improved … WebJul 22, 2024 · Three factors that affect magma viscosity are temperature composition and presence of dissolved gases. How does magma viscosity influence the explosive potential? A more viscous (thick) magma will produce a more violent eruption This is controlled in part by the concentration of silica in the magma.
WebJul 7, 2024 · How does magma viscosity affect a volcano’s topographic profile? The low viscosity of the magma allows the lava to travel down slope on a gentle slope, but as it cools and its viscosity increases, its thickness builds up on the lower slopes giving a somewhat steeper lower slope. Most shield volcanoes have a roughly circular or oval … WebJun 11, 2024 · The composition and viscosity of magma determines both its eruptive style and the rock type that will be formed when it cools. The three main types of lava, named for the rock types that they form, are basaltic (for basalt ), rhyolitic (for rhyolite ), and andesitic (for andesite ).
WebSep 3, 2024 · Felsic magmas are higher in silica and contain lighter colored minerals such as quartz and orthoclase feldspar. The higher the amount of silica in the magma, the higher is its viscosity. Viscosity is a liquid’s resistance to flow. Viscosity determines what the magma will do. Mafic magma is not viscous and will flow easily to the surface. Web2. what are the top two compositions of magma Explanation: When magma flows or erupts onto Earth's surface, it is called lava. 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.
WebThe composition of the gases in magma are: Mostly H 2 O (water vapor) with some CO 2 (carbon dioxide) Minor amounts of Sulfur, Chlorine, and Fluorine gases The amount of gas in a magma is also related to the …
WebMagma that does make it to the surface, lava, forms finer-grained rocks that are called extrusive. Bowen's Reaction Series As a magma, or lava, cools, it will form crystals in a very orderly progression. The ferro-magnesian minerals, those that require Fe and Mg in their formation, will crystallize in order and at the expense of one another. daycares that pick up kids from schoolWebMay 6, 2024 · Magmas can vary widely in composition, but in general they are made up of only eight elements; in order of importance: oxygen, silicon, aluminum, iron, calcium, sodium, magnesium, and potassium (Figure 3.2. 1 ). Oxygen, the most abundant element in magma, comprises a little less than half the total, followed by silicon at just over one … daycares that take newbornsWebThe magma forming this lava is often felsic, having high-to-intermediate levels of silica (as in rhyolite, dacite, or andesite ), with lesser amounts of less-viscous mafic magma. [2] Extensive felsic lava flows are uncommon, but have travelled as far as 15 km (9 mi).
