There are three basic types of magma: basaltic, andesitic, and rhyolitic, each of which has a different mineral composition. All types of magma have a significant percentage of silicon dioxide. Basaltic magma is high in iron, magnesium, and calcium but low in potassium and sodium. Meer weergeven Magma is extremely hot liquid and semi-liquid rock located under Earths surface. Earth has a layered structure that consists of the inner core, outer core, mantle, and crust. Much of the planets mantle consists of magma. … Meer weergeven Like solid rock, magma is a mixture of minerals. It also contains small amounts of dissolved gases such as water vapor, carbon … Meer weergeven The viscosity (thickness) of the magma that erupts from a volcano affects the shape of the volcano. Volcanoes with steep slopes tend to form from very viscous magma, while flatter volcanoes form from … Meer weergeven WebThe low viscosity of basaltic lavas allows them to be extruded over great distances, often producing high-volume lava flows with low aspect ratios (ratio of thickness to area). Under the right conditions, de-gassed felsic magmas can also erupt lava in a nonviolent manner.

WebBasaltic magma is high in iron, magnesium, and calcium but low in potassium and sodium. 2. 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.

Tall eruption columns with http://sci.sdsu.edu/how_volcanoes_work/Controls.html WebViscosity of Some Common Magmas Notes: (1) rapid increase in viscosity of basaltic magma when crystals form (below ~1200ºC) and/or gas bubbles exsolve. Thus, basaltic magmas tend to be fairly fluid (low viscosity), but their viscosity is still 10,000 to 100,0000 times more viscous than water. questions on kinetic energy class 9
