Detailed explanation-1: -The gases in the magma bubble out gently. Low-silica lava oozes quietly from the vent and can flow for many kilometers. Quiet eruptions can produce two different types of lava that differ in temperature. Pahoehoe is fast-moving, hot lava that is thin and runny.
Detailed explanation-2: -Shield volcanoes Where a volcano produces low viscosity, runny lava, it spreads far from the source and forms a volcano with gentle slopes: a shield volcano. Most shield volcanoes are formed from fluid, basaltic lava flows. Mauna Kea and Mauna Loa are shield volcanoes.
Detailed explanation-3: -Pahoehoe (Pa-Hoy-Hoy) lava flows are very hot, thin and runny. When it cools is has a smooth to ropey texture because of the low silica content which makes it cool quickly. Pahoehoe flows creep along generally at less than 3 feet per minute but some flows have been measured at over 20 miles per hour.
Detailed explanation-4: -Vulcanian eruption is a silent eruption due to oozing lava. B. Strombolian eruption is an eruption characterized by fountain lava.
Detailed explanation-5: -An effusive eruption is a type of volcanic eruption in which lava steadily flows out of a volcano onto the ground.
