Constructive and destructive forces of a volcano?

Answer 1

Volcanoes are both, constructive and destructive. They are constructive, by forming landforms and islands. They are destructive, because they can destroy anything in the lava's way when it erupts, by tearing down buildings with lava and black smoke with such a force.

it also puffs out poison ash when it erupts.

Answer 2

: When Mount St. Helens erupted on May 18, 1980, red hot lava did not spew out of the volcano and pour down its flanks. This perception of a volcanic eruption is a common one and is probably due in part to pictures seen on television or in hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhbooks of the beautiful lava flows and lava fountains in Hawai'i. The type of eruptions in Hawai'i are known as hawaiian volcanism and are far less dangerous than the eruptions produced by Mount St. Helens. It is important to know what type of an eruption a volcano is most likely to produce so that the types of hazards produced by such an eruption can be identified. Knowledge of these types of hazards, will help determine where a person would need to go to be safe during a volcanic eruption. : Volcanic eruptions can be placed into two general categories: those that are explosive, such as at Mount St. Helens, and those that are effusive, such as in Hawai'i. The most active volcano in the world, Kilauea Volcano on the big island of Hawai'i, is generally a nonexplosive volcano (though there have been occasions when it erupted explosively). Eruptions from it normally result in gently flowing lava flows, spatter cones, and lava fountains. Another type of nonexplosive volcanism is flood basalts. Lava flows from this type of eruption are extruded from fissures and cover vast areas. These nonexplosive eruptions are the least dangerous type of volcanic eruption since people rarely get killed by them (Francis, 1993). However, they are devastating and may have global consequences. : Many eruptions are explosive in nature. They produce fragmental rocks from erupting lava and surrounding country rock. Some eruptions are highly explosive and produce fine volcanic ash that rises many kilometers into the atmosphere in enormous eruption columns. Explosive activity also causes widespread ash fall, pyroclastic flows, debris avalanches, landslides, pyroclastic surges, and lahars. Explosivity is usually the result of gases expanding within a viscous lava. Another mechanism for explosions at volcanoes occurs when surface water or ground water enters a magma chamber. These eruptions are likely when a volcano occurs in a wet area or in the sea.

Answer 3

Volcanoes are both constructive forces, and destructive fores, because

a volcanoes can make a destroy land because when a volcanoes erupt they mostly destroy everything around it but say if a volcanoes erupt in side water the water will cool down the lava and make it in to new land that is how we go islands

mostly every land that you see or walk on was made by a volcanoes or any other forces

Answer 4

Constructive forces of a volcano include the formation of new land through the deposition of lava and ash, as well as the creation of fertile soil that supports plant growth. Destructive forces of a volcano involve the potential for destructive eruptions that can cause loss of life, property damage, and environmental hazards like pyroclastic flows, lahars, and volcanic ash fall.

Answer 5

Volcanoes can create more real estate. Take the Hawaiian islands for example. Created by volcanism.

Answer 6

volcanos are both destructive and constructive . how? because when a volcano erupts it blows rock then every time it blows more rock and that is how you make another volcano!

Answer 7

a volcano is both constructive and destructive force well because a volcano makes lava out of magma and well the destructive it breaks down rocks.
