CINDER CONE Cinder Volcanoes are the simplest type of volcano. They are
built from particles and blobs of congealed lava ejected from a single vent.
Lava is blown into the air, which breaks into small fragments that solidify and
fall as cinders around the vent to form a circular or oval cone. Most cinder
cones have a bowl-shaped crater at the summit, and rarely rise more than a
thousand feet or so above their surroundings.
COMPOSITE Typically, composite volcanoes are steep-sided, symmetrical
cones of large dimension built of alternating layers of lava flow, volcanic ash
and cinders. Composite volcanoes will rise as much as 8,000 feet above their
base. Most composite volcanoes have a crater at the summit, which contains
a central vent or a clustered group of vents. One essential feature about
composite volcanoes is the conduit system. This is when the magma from a
reservoir deep in the Earth's crust rises to the surface. This type of volcano is
built by the accumulation of materials erupted through the conduit, which
increases in size as lava, cinders, and ash are added to its slopes.
SHIELD
Shield volcanoes are built almost entirely of fluid lava flow. Flow after flow
pours out in all directions from a central summit vent, which builds a broad,
gently sloping cone - much like a warrior's shield or a plateau. Shield
volcanoes can be easily identified because they are tall and broad, with flat,
rounded shapes. The lava is not accompanied by pyroclastic materials, which
makes shield volcanoes relatively safe (as shown in this picture) of scientists
monitoring the eruption. Mauna Loa, the largest of the shield volcanoes, is
13,677 feet above sea level, which means it rises over 28,000 feet above the
deep ocean floor, and would be the world’s tallest mountain if much of it
were not underwater. Famous shield volcanoes include Mauna Loa, Kilauea,
(two of the world's most active volcanoes), and Olympus Mons of Mars.
