Question

State the two causes of volcanic
eruption and its two advantages​

Answer 1

Answer:

$\huge\tt\underline\red{answer}$

the two causes of volcanic eruption are:

1)when a part of the earth's upper mantle or lower crush melts,magma forms.a volcano is essentially an opening or a vent through which this magma and the dissolved gases it contains are discharged.

2)the expanding carbon dioxide gas creates pressure and pushes the magma up the vent of the volcano,causing an eruption.

two advantages of volcanic eruption are:

1)Lava and Ash deposited during an eruption breaks down to provide valuable nutrients for the soil... this creates very fertile soil which is good for agriculture.

2)Volcanoes attract many tourists, who enjoy the dramatic scenery that they produce. Rising magma brings valuable minerals to the surface, creating mining opportunities.

Answer 2

Answer:

$\huge\underline\red{Two \: Causes \: Of \: Volcanic \: Eruption}$

1. Although there are several factors triggering a volcanic eruption, three predominate: the buoyancy of the magma, the pressure from the exsolved gases in the magma and the injection of a new batch of magma into an already filled magma chamber.
2. The style of eruption depends on a number of factors, including the magma chemistry and content, temperature, viscosity (how runny the magma is), volume and how much water and gas is in it, the presence of groundwater, and the plumbing of the volcano.

$\huge\underline\blue{Two \: Advantages \: Of \: Volcanic \: Eruption}$

1. Volcanic materials ultimately break down and weather to form some of the most fertile soils on Earth, cultivation of which has produced abundant food and fostered civilizations. The internal heat associated with young volcanic systems has been harnessed to produce geothermal energy.
2. 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.
