Question

state two causes of volcanic eruption and its two advantages​

Answer 1

Answer:

causes of volcanic eruption are:-

1.a volcano to erupt which all fundamentally come down to a pressure change within the volcano which forces the magma to overflow the chamber it is held in.

2.When one is pushed under the other the magma, sediment and seawater is forced into the chamber which eventually overflows and the volcano erupts spewing lava into the sky.

advantages of volcanic eruption are:-

1.Volcanic materials ultimately break down and weather to form some of the most fertile soils on Earth, cultivation of which has produced geothermal energy.

2.Most of the metallic minerals mined in the world--such as copper, gold, silver, lead, and zinc--are associated with magmas found deep within the roots of extinct volcanoes.

Answer 2

ADVANTAGES:

They helped cool off the earth removing heat from its interior. Volcanic emissions have produced the atmosphere and the water of the oceans. Volcanoes make islands and add to the continents. Volcanic deposits are also used as building materials.

Explanation:

CAUSES:Major health threats from a volcanic eruption

People have died from volcanic blasts. 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.
