WebThe form and style of eruption of a volcano is largely determined by the composition of the lava it erupts. The viscosity (how fluid the lava is) and the amount of dissolved gas are the …
WebShield Volcano. A shield volcano is a broad volcano with shallow inclining sides. Shield volcanoes are formed from many magma flows of low viscosity. The magma flows out of the vent and slides down the slopes of the volcano and builds up the size. A shield volcano is named so due to their similarity to a warrior’s shield lying on the ground. WebVolcanoes also form in places where two plates slowly pull apart. Molten rock rises between the plates as they move apart. It causes fissure eruptions, in which lava flows out over the ground. This type of volcano is common along the Mid-Atlantic Ridge, a mountain chain under the Atlantic Ocean.
WebThere are two main ways Earth materials melt: 1) hot mantle rises and decompresses; and 2) water flows through hot rock. The first type of melting occurs at diverging plate … WebMay 29, 2024 · There are three settings where volcanoes typically form: constructive plate boundaries. destructive plate boundaries. hot spots. Why can volcanoes sometimes have more than one kind of eruption? A volcano forms where a crack in the earth’s crust allows magma and gases to come to the surface.
WebVolcanoes erupt because of the way heat moves beneath Earth ’s surface. Heat is conveyed from the planet’s interior to its surface largely by convection —the transfer of heat by movement of a heated fluid. In this case, the fluid is magma —molten or partially molten rock —which is formed by the partial melting of Earth's mantle and crust.
WebSep 1, 2024 · The volcanoes form steep cones, rather than rounded shapes, because the magma is viscous. Composite volcano magma is felsic, which means it contains silicate-rich minerals rhyolite, andesite, and dacite. Low-viscosity lava from a shield volcano, such as might be found in Hawaii, flows from fissures and spreads. high end toilet plungerWebHow do volcanoes erupt?
