Read the following passage.
A. A volcano is an opening, or vent, in the Earth's surface where lava, small rocks called tephra and steam erupt. Below ground, molten rock is known as magma; once it erupts it is called lava. Magma is lighter than the solid rock around it, so it is driven upward toward the surface. Most volcanic activity happens along the boundaries of tectonic plates or above hotspots. There are about 1,350 potentially active volcanoes worldwide, not counting those under the oceans. The best-known types are cinder cones, composite volcanoes and shield volcanoes, and lava domes are often described alongside them.
B. Cinder cones are the simplest type, and they are the most common volcano in the world. They form when gas-charged lava is blown violently into the air from a single vent. The lava breaks into small pieces that harden and fall as cinders, piling up into a round or oval cone with a bowl-shaped crater on top. A cinder cone usually erupts only once, and the eruption is often brief: half of all historic cinder cone eruptions lasted less than 30 days. In 1943 one began growing on a farm in Mexico and destroyed the town of San Juan.
C. Shield volcanoes are the largest volcanoes on Earth, yet they do not form steep peaks. They are built almost entirely of very fluid lava, which pours out from vents at the summit or from cracks on the flanks called rift zones. Thousands of these flows spread over great distances and cool as thin sheets, so the volcano grows into a broad, gentle dome shaped like a warrior's shield lying flat. Shield volcanoes are much wider than they are tall: the base of Mauna Loa in Hawaii is about 160 kilometres wide. Mauna Loa, the largest active volcano on the planet, has erupted 34 times since 1843.
D. Composite volcanoes, also called stratovolcanoes, are tall, steep cones made of layers of lava, ash and rock, such as Mount Fuji in Japan. Lava domes form when lava is too thick to flow far, so it piles up over and around the vent, often inside the crater of a composite volcano. As a dome grows from within, its cooler outer surface can shatter and send hot rock and gas down the mountain. In 1980 a huge landslide removed the top 400 metres of Mount St. Helens. Mount Rainier is considered the most dangerous volcano in the lower 48 states, and its greatest hazard is destructive mudflows called lahars.
