Nature is fraught with many surprises. Each phenomenon has a wonderful and terrible side: volcanoes are one of the most striking examples of such duality. Fiery peaks are found all over the planet, but while some of them scare the constant eruptions, others lurked for a while. What do scientists know about this amazing phenomenon?
Constant threat
For many people on Earth, the appearance of lava flowing from the crater does not seem shocking. Fiery rivers against the background of farm houses are an ordinary picture, because a person is not averse to settle next to a dangerous area for the sake of fertile soil.
And even a mixture of poisonous gases escaping from under the stones can turn into something amazing. When poison is mixed with oxygen, flashes of an unusual color appear.
Thick clouds of ash not only make breathing difficult. They fill the air with small particles, which endlessly create an incredible amount of static electricity. In such a situation, lightning is a natural development of events.

Especially dangerous are subsea eruptions that are invisible for the time being. Their influence on the world manifests itself in different ways, often leading to the formation of entire archipelagos in the open ocean.
Global effect
But is it only the negative effects that a person observes? Today, astronauts from orbit send pictures of the results of volcanic activity. A column of dust and ashes of enormous size!
Lava is perceived as a threat. Its effect on the outside world is the destruction of all available life. Emerging from the crater, it burns out the flora and fauna, leaving behind a lifeless wasteland.

But this is not the whole truth. Let volcanoes demonstrate the fragility of life, ready to break into many fragments with just one blow. At the same time, they provide the necessary resources for the development of biological diversity, push nature to evolution.
An unprecedented amount of useful elements is hidden in the earth's interior. This is not only about precious metals, but also about nutrients, which after cooling become the basis for the soil. The most devastating eruptions give courageous farmers room to grow rich crops. For his sake, people take risks to this day!
