1.What explain the destruction caused by a volcano eruption
2.explain the term magma
3.what were the findings of scientists at the U.S. Geological survey
Answers
Answer:
Deep within the Earth it is so hot that some rocks slowly melt and become a thick flowing substance called magma. Since it is lighter than the solid rock around it, magma rises and collects in magma chambers. Eventually, some of the magma pushes through vents and fissures to the Earth's surface.
Answer:
Answer 1st : Volcanoes spew hot, dangerous gases, ash, lava, and rock that are powerfully destructive. ... The most common cause of death from a volcano is suffocation. Volcanic eruptions can result in additional threats to health, such as floods, mudslides, power outages, drinking water contamination, and wildfires.
Answer 2nd : Magma is a mixture of molten and semi-molten rock found beneath the surface of the Earth.Magma comes from an Italian word that means a thick, pasty substance, which is how molten rock behaves within the Earth. Lava, another Italian word, means to slide, which is what molten rock does once it reaches the surface
Answer 3rd : The United States Geological Survey (USGS, formerly simply Geological Survey) is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility.
