Three Types of Volcanoes: Cinder Cones by Kelly Peskura https://padlet.com/kpeskura15/i1jaorny0wht For the three types of volcanoes, I want you to explain to me what a cinder volcano is, what are they made of, an example of where this volcano can be found (a picture as well) and any other important pieces of information you want to share! en-us 2016-11-01 13:40:25 UTC 2025-09-24 04:20:59 UTC hello@padlet.com Cinder cones consist of cinders, more properly called scoria. Scoria is very vesicular, low density basalt. kpeskura15 https://padlet.com/kpeskura15/i1jaorny0wht/wish/134470005 2016-11-01 13:44:02 UTC https://padlet.com/kpeskura15/i1jaorny0wht/wish/134470005 Lava fountains are driven by expanding gas bubbles; the bubbles are trying to expand in all directions but the only way to relieve the pressure is up out the vent so fountains are usually directed relatively vertically. kpeskura15 https://padlet.com/kpeskura15/i1jaorny0wht/wish/134470146 2016-11-01 13:44:20 UTC https://padlet.com/kpeskura15/i1jaorny0wht/wish/134470146 Cinder cones tend to be roughly circular. They are usually formed later in an eruption when activity has localized to one or more discrete vents. kpeskura15 https://padlet.com/kpeskura15/i1jaorny0wht/wish/134470382 2016-11-01 13:44:51 UTC https://padlet.com/kpeskura15/i1jaorny0wht/wish/134470382 If the precise location of the vent changes during an eruption, the cone loses its simple circular shape, and becomes more complex. kpeskura15 https://padlet.com/kpeskura15/i1jaorny0wht/wish/134470583 2016-11-01 13:45:19 UTC https://padlet.com/kpeskura15/i1jaorny0wht/wish/134470583   The reddish color is common to cinder cones and occurs both during and soon after the associated eruption due to the combined efforts of moisture and oxidizing gases. kpeskura15 https://padlet.com/kpeskura15/i1jaorny0wht/wish/134470780 2016-11-01 13:45:48 UTC https://padlet.com/kpeskura15/i1jaorny0wht/wish/134470780 Cinder cones can also be distinctly asymmetric if there was a persistent wind blowing during the eruption and/or they form at the heads of major lava flows. kpeskura15 https://padlet.com/kpeskura15/i1jaorny0wht/wish/134470969 2016-11-01 13:46:10 UTC https://padlet.com/kpeskura15/i1jaorny0wht/wish/134470969 In this second instance they are horseshoe-shaped (see below), with the lava flow issuing out of the open end because during the eruption any pyroclasts that landed on the flow were rafted away. kpeskura15 https://padlet.com/kpeskura15/i1jaorny0wht/wish/134471151 This image is a horsehow shaped lava flow!]]> 2016-11-01 13:46:34 UTC https://padlet.com/kpeskura15/i1jaorny0wht/wish/134471151 This is an example and image of a cinder cone volcano! Wizard Island is located in Crater Lake National Park, Oregon. kpeskura15 https://padlet.com/kpeskura15/i1jaorny0wht/wish/134472418 2016-11-01 13:49:37 UTC https://padlet.com/kpeskura15/i1jaorny0wht/wish/134472418 This is another example and image of a cinder cone volcano. Amboy Crater is located in southern California. At this moment in time, this volcano is extinct. kpeskura15 https://padlet.com/kpeskura15/i1jaorny0wht/wish/134473193 2016-11-01 13:51:24 UTC https://padlet.com/kpeskura15/i1jaorny0wht/wish/134473193
