The negative effects of volcanoes include the destruction of man-made and natural environments and the death of human, animal and plant life. On the other hand, volcanoes generate geothermal energy and produce nutrients that result in fertile soil.Know More
The most glaring negative effects of volcanoes are death and destruction, including loss of human life. While lava flows are dangerous to nearby structures and buildings, ashfall is deadly. According to Volcano World, if ash is heavy enough, it causes buildings to collapse. The ash slowly suffocates people by making breathing nearly impossible or aggravating respiratory problems. Another cause of death is pyroclastic flow, which is a combination of hot gas and ash. Pyroclastic flows are too fast to outrun, and they are so hot and cloying that they kill people and animals instantly.
While the negative effects of volcanoes are very serious, there are also some very positive effects. For one, the lava and ash are rich in nutrients. According to the BBC, they break down into the soil and make very fertile farmland. Volcanoes are also good sources of geothermal energy, provided a structure is in place to capture it. Finally, volcanoes create remarkable scenery that is great for tourism.Learn more about Volcanoes
No two volcanoes are exactly the same, as they all have differences in dimensions of their mountains and craters, as well as their relative frequency and type of eruption. Volcanoes come in cinder cone, shield and stratovolcano varieties.Full Answer >
Volcanic vents allow the Earth to release built up gases from the heat and pressure emanating from its core. Magma rises towards the surface, and as the pressure builds the magma seeks outlets through which to flow. The higher the pressure build-up, the greater the volcanic explosion.Full Answer >
Most volcanoes occur in the basin of the Pacific Ocean, also known as the Ring of Fire. Most volcanoes are situated on the edges of tectonic plates. One of the largest of these tectonic plates, the Pacific plate, is the area around which the majority of volcanoes lie.Full Answer >
The four main types of volcanoes are cinder cones, composite volcanoes, shield volcanoes and lava domes. These volcanoes have different shapes and types of eruptions.Full Answer >
