What kind of volcano am I? (Chart Reading/Diagram 2).
After learning about the basic kinds of volcano volcano, vents or fissures in the earth's crust through which gases, molten rock, or lava, and solid fragments are discharged. Their study is called volcanology. formations, read the descriptions of the real-life real-life
Actually happening or having happened; not fictional: a documentary with footage of real-life police chases. volcanoes below. Then answer the question: What kind of volcanic formation am I-- cinder cone cinder cone
or ash cone
Deposit around a volcanic vent, formed by rock fragments or cinders that accumulate and gradually build a conical hill with a bowl-shaped crater at the top. , composite, caldera caldera: see crater.
Large, bowl-shaped volcanic depression that forms when the top of a volcanic cone collapses into the space left after magma is ejected during a violent volcanic eruption. The term is Spanish for “caldron. , shield volcano shield volcano
See under volcano. , or lava dome In volcanology, a lava dome or plug dome is a roughly circular mound-shaped protrusion resulting from the slow eruption of felsic lava (usually rhyolite and/or dacite) from a volcano. ?
A volcano, 2,272.3 m (7,450 ft) high, of west-central Mexico west of Mexico City. It erupted from a cornfield in February 1943 and grew more than 458 m (1,500 ft) in that year alone. : cider cone cone, in botany
cone or strobilus (strŏb`ələs), in botany, reproductive organ of the gymnosperms (the conifers, cycads, and ginkgoes).
Crater Lake Crater Lake
Lake, Cascade Range, southwestern Oregon, U.S. The lake is in a huge volcanic caldera 6 mi (10 km) in diameter and 1,932 ft (589 m) deep. It is the remnant of a mountain destroyed in an eruption more than 6,000 years ago. : caldera Mauna Loa Mauna Loa (mou`nə lō`ə), mountain, 13,680 ft (4,170 m) high, in the south central part of the island of Hawaii, in Hawaii Volcanoes National Park. Its many craters include Kilauea and Mokuaweoweo, two of the world's largest active craters. : shield volcano
Novarupta Novarupta, meaning "new eruption", is a volcano located on the Alaska Peninsula in the Katmai area, about 290 miles southwest of Anchorage. Novarupta sits below Mount Katmai. Its eruption of June 6–June 8, 1912, was ten times more powerful than the 1980 eruption of Mount St. : lava dome

NAME/ SIZE LAST ERUPTION LOCATION Paricutin, 424 meters In 1943, a Mexican farmer discovered Mexico (1,391 feet) steam rising from his cornfield. Soon high an explosion of hot ash shot up through a vent. Gas that had been trapped inside the Earth rapidly expanded and escaped, turning molten lava into cinders. Within days, a towering volcano stood in place of the field. The last eruption in 1952 left a funnel-shaped crater at the top. What kind of volcano am I?-- Crater Lake, 52 sq km Thousands of years ago, a prehistoric Oregon (20 sq miles), volcano called Mount Mazama stood 589 m where Crater Lake lies today. (1,932 ft) Scientists theorize that magma beneath deep the volcano drained through underground channels. The peak collapsed inward, leaving behind a huge basin that eventually filled with rainwater and snow. What kind of volcano am I? Mauna Loa, 4,170 m Mauna Loa is one of the world's Hawaii (13,681 ft) largest volcanoes. Lava from Mauna above sea Loa--in the form of basalt level rock--covers about 50 percent of the island of Hawaii. The volcano erupts every few years, but the eruptions last for only a few days. In 1984, earthquakes preceded an eruption, offering people nearby an early warning. Eruptions at Mauna Loa are famous for their "curtains of fire" --fountains of extremely fluidlike lava. What kind of volcano am I?-- Novarupta, 841 m In June 1912, a new volcano--Novarupta Alaska (2,759 ft) --erupted violently on the flanks of high Katmai Volcano. A thick mound of lava then rose from within the volcano and fanned outward, blocking the vent. The pent-up pressure inside the vent resulted in a huge explosion that showered volcanic ash over Kodiak Island and much of Alaska's mainland. Eventually the slow-flowing lava hardened and formed the rounded cap seen today. What kind of volcano am I?-- Mount 2,549 m In 1980, after 123 years of dormancy, St. Helens, (8,363 ft) Mount St. Helens blew its top. The Washington high first eruptions, in March, shot ash and vapor more than 6,600 m (21,654 ft) into the sky. On May 18, a bulge of magma blasted through the side of the mountain. A plume of ash rose to an altitude of about 19 km (12 mi). Fifty-seven people died during that eruption. If you flew into the crater of Mount St. Helens, you would see the layers of ash and hardened lava that built up the volcano during past eruptions. What kind of volcano am I?--
