Q:

What are the benefits of living near a volcano?

A:

Quick Answer

The benefits of living near a volcano are enriched soil, opportunities to efficiently harness geothermal energy and potential tourist income. Metals and precious stones are also common in volcanic soil, and rivers flowing on volcanoes can be used to generate hydroelectricity.

Volcanoes often create favorable weather conditions in the surrounding area, particularly in tropical locations. The higher elevation of the volcano gives it cooler temperatures than low-lying tropical areas. This added elevation also affects precipitation: the area surrounding a volcano receives more frequent rainfall.

Richer soil and more frequent rainfall make the areas near volcanoes ideal farmland. In areas with periodic volcanic eruptions and lava flows, the soil is refreshed with each new deposit of volcanic material. This benefit can persist for centuries; the area around Mount Vesuvius in Italy has been fertile farmland since before the beginning of recorded history due to volcanic activity.

Many densely populated areas coexist with active volcanoes. This is particularly true in tropical areas, where the cooler temperatures and superior farmland do not exist elsewhere. Indonesia, the Philippines and developing countries in South America are cited as regions of particular concern by NASA's Earth Observatory; population growth around potentially dangerous volcanoes is highest in these regions.

    What is a passage followed by magma in a volcano called?

    A:

    A passage followed by magma inside a volcano or underground is called a conduit. Magma typically consists of molten or partially molten rock, and it may contain crystallized minerals, xenoliths from the conduit, a liquid portion or melt, and dissolved gases. Once magma reaches the surface, it is considered lava.

    What is a dome volcano?

    A:

    A dome volcano, or a lava dome, occurs when a dome forms over the vent of a volcano because the eruption is too slow. Once the lava cools down, it forms a dome. The domes are typically fairly steep and filled with silica-rich lava, which is prone to explosions.

    What type of volcano is Mount Mazama?

    A:

    Mount Mazama is a composite volcano. It is made of multiple layers of lava flows and fragmented debris. Mount Mazama had a violent eruption around 5677 B.C., which caused the main height of the volcano to collapse and create a caldera, which holds Crater Lake.

  • Q:

    What do you call a volcano that no longer erupts?

    A:

    A volcano that no longer erupts but has the potential to erupt again is called a dormant volcano. If the volcano has not erupted for at least 10,000 years and is unlikely to erupt again in the foreseeable future, it is called an extinct volcano. These types of volcanoes are different from an active or erupting volcano.
