How Do Volcanoes Affect The Environment

Volcanoes are natural disasters that the human race can recover from eventually. Though it is true that every volcano eruption has cons , but on the positive side it helps the environment. The volcanoes main effect is to provide nutrients to the surrounding soil. Volcanic ash often contains minerals that are beneficial to plants, and if it is very fine ash it is able to break down quickly and get mixed into the soil. Volcano gases are a main source of water and most of the atmosphere.

A volcano is an earth hazard that occurs on faults between tectonic plates on a destructive boundary and an eruption is a natural disaster. A primary impact happens immediately after the disaster and before any response like death or collapsing or destruction of buildings. A secondary impact occurs later after the disaster, such less farm produce or a reduction in tourism. The severity of these impacts will differ considerably in a MEDC and LEDC where volcanic eruptions have taken place. These may be seen in the Mount St. Helen volcano eruption as well as in the Iceland volcanic eruption. They may also

Volcanoes are one of the most destructive, yet, most beautiful things on Earth. They can make a famous city choke in its own ashes in one day, like Pompeii. Or they can turn a once damaging mountain into a graceful and peaceful home for new life, like Mount St. Helen’s. All volcanoes are unique, and no two are the same. Some erupt differently than others, some look different than others, and all are located in different spots all over the world. I learned this while completing the project and the five volcanoes I researched are examples of my discoveries. The five volcanoes I researched were Mount Hood, Mount Mageik, Long Island, Mount Muria, and Las Pilas.

The location of the volcano is also important. If it is situated on a constructive plate boundary then it is generally less explosive, and therefore poses different threats to volcanoes situated on a destructive plate boundary. The volcano may also be situated on a hotspot like in Hawaii, where the eruptions aren’t very explosive. Volcanos which aren’t explosive can pose other threats to lava flows though, such as dangerous gases being released. Like in Lake Nyos, Cameroon where 1700 people died.

How did the described volcanoes in Iceland and the Philippines change the environment to lesser or greater extents?

the volcano and the areas ecology - learning about things science has not had the chance to

One of the many great things that happens after a volcano’s eruption is enrichment of the soil around a volcano. Volcanic eruption creates a large amount of rock and ash within the area to which the eruption occurred, (Source Two: Volcanic Soils, paragraph one, lines one and two). The rock and ash released from a volcanic eruption offers a bountiful amount of minerals that seep into the soil. If you were a plant, growing in this soil would be like eating at Golden Corral every night of your life. Along with this, the volcanic soils easily trap moisture, giving farmers a much easier job tilling the ground, (Source Two: Volcanic Soils, paragraph five, lines two and three).

Most people would seriously question on why so many people throughout the world live in the immediate vicinity of a volcano, and although we can only see the downside of that, there are benefits from living so close to a volcano. One of the biggest reasons are the soils close to a volcano is full of nutrients and minerals which keep the soil very fertile. This happens because of all of the lava and rock that a volcano releases. This helps soil stay rich with nutrients and gives opportunities to grow fruit, rice or other

To understand why it's good to farm around volcano's you must first understand what Photosynthesis. Photosynthesis is the process that keeps plants alive. For this to work you need four things and one extra thing to help. First, most importantly, you need lots of sunlight. Second you need damp soil or a irrigated water source. Third you need carbon dioxide which the plants use for making their food and then excreats oxygen. Also to help the plants grow faster a riper you should really have rich soil. Soil with minerals and nutrients make the plants bigger, stronger and faster

There are many things to know about volcanoes, they can be active for thousands of years, and also according to “How many active volcanoes are there?” it says “At least 20 volcanoes will probably be erupting as you read these words.” So how many active volcanoes are there?

In conclusion, despite volcanos being a very popular topic to put under the bus, volcanos ironically help the human race by giving them new land to farm on, live on, explore and etcetera. Although these volcanos ironically help us as a race, the volcanos also kill many people whilst preforming said help.

How volcanoes affect people and environments? A volcano is a mountain or hill having a crater or vent through which lava, rock fragments, hot vapor, and gas are in. Volcanoes can change the weather. They can cause rain, thunder and lightning. Volcanoes can also have long-term effects on the climate, making the world cooler.

Recently there has been a lot of research in the field of climate change, and much of it is focused on anthropogenic affects on climate. However, there has also been a great deal of research focused on natural Earth processes and how they affect the climate (Robock 2000). One natural process which significantly impacts climate is volcanic eruptions. Volcanic eruptions affect the climate of the earth in many ways (Zielinski et al 1997). Volcanic ash ejected during eruptions effect climate by reflecting solar rays back into space, and thus cooling the surface of the Earth. Another way volcanoes affect the Earth’s climate, is the emission of many different types of volcanic gasses.
