Iceland - Many forms of Lava │ Part 184
* * * Which type of Lava do you like * * * The most common way to divide lava flows into distinct types is following: Pahoehoe lava flow, Aa lava flow, Blocky lava flow, and also Pillow lava flow. Sometimes Turbulent lava flow is also added, but the latter is only of theoretical interest to scientist because we will not see that type of lava flow in the nature. Turbulent lava flows may have been present billions of years ago when the interior of the Earth and consequently lava flows as well were significantly hotter and the composition of lava was less siliceous. That enabled the lava to flow more easily and turbulently. The most common subaerial lava flows today are pahoehoe, aa, and blocky lavas. Pahoehoe is a smooth and continuous lava crust. Pahoehoe forms when the effusion rate is low and consequently the velocity of lava flow is slow2. Pahoehoe lava flow is usually at least 10 times slower than typical aa lava flow Aa lava is a rough rubbly crust of a lava flow. It is a major lava flow type. Other important subaerial lava flow types are pahoehoe and blocky lava. Aa and pahoehoe are terms that were brought to geological terminology from the Hawaiian language. Blocky flows are common if the silica content of lavas is higher (composition of basaltic andesite to rhyolite). Blocky lava flows resemble aa lavas. They also have highly irregular surfaces covered with debris, but they contain larger lava blocks with smoother sides and angular edges with common dimensions from few decimeters to several meters. Blocky flows grow higher as they advance and may reach more than 100 meters in height. Pillow lava is usually basaltic or andesitic in composition and always associated with water. Pillows are about one meter across each or smaller and form when lava flows out of the Earth’s crust underwater. Each pillow is like a bag that has quickly chilled margin which is filled with molten material. Pillow lavas are usually associated with mid-ocean ridge volcanism - - - - - - - - - - - - - - - - - - *** TIMEFRAME *** 00:00 let’s look at some lava formations - - - - - - - - - - - - - - - - - - - if you are a fellow video creator, let me support you too. – Please watch the video in 2K because the compression is so high in HD that it degrades the image quality - - - - - - - - - - - - - - - - - - Thank you for watching.
