What Are The Positive And Negative Effects Of Volcanic Activities?
VOLCANIC ACTIVITIES – In this topic, we will now know the following positive and negative effects of volcanic activities.
We will know some basic information about the volcano first.
According to a Prezi presentation published by R’smond:) Rachmaninov, a volcano is a mountain that opens downward to a pool of molten rock below the earth. Volcanic eruption occurs when pressure builds up.
These are usually located where tectonic plates meet. This is specifically accurate in the case of the Pacific Ring of Fire where 75% of the earth’s volcanoes are found.
Here are the following positive and negative effects of such activity:
- Positive Effects
- The dramatic scenery created by the eruptions attracts tourists, hence, bringing more income to that area.
- The lava and ash from the eruption breaks down to provide valuable nutrients for the soil. These produce very fertile soil that is good for future planting of different vegetables or other plants.
- The steam that is released during an eruption could be utilized to move the turbine that could produce energy. This is called geothermal energy.
- Negative Effects
- Man made and natural landscapes can be destroyed and will be changed forever.
- When ash and mud from the eruption is mixed with rain water or melting snow, rapid mudflows are produced. This can also trigger flash floods, and rock fall.
- Countless lives will be lost due to the eruption.
