S ome of the Earth's grandest mountains are composite volcanoes--sometimes called stratovolcanoes. They are typically steep-sided, symmetrical cones of large dimension built of alternating layers of lava flows, volcanic ash, cinders, blocks, and bombs and may rise as much as 8,000 feet above their bases. inder cones are the simplest type of volcano. They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone.
Otaku is a Japanese slang word, deriving from the honorific ããã (otaku), meaning your house, that has come to mean someone who obsessively exerts time, money, and energy into a hobby.
In Western anime fandom, otaku is used interchangeably with anime fan(s), but that's not quite what it means in Japan. While anime - particularly late-night shows aimed at less mainstream audiences - are often associated with otaku, an otaku is not necessarily an anime fan. An otaku is an obsessive fan of any topic.
