VOLCANOES

What causes the type of extreme weather?

Major health threats from a volcanic eruption. Volcanoes spew hot, dangerous gases, ash, lava, and rock that are powerfully destructive. ... The most common cause of death from a volcano is suffocation.

Where have they occurred?

sixty percent of all active volcanoes occur at the boundaries between tectonic plates. Most volcanoes are found along a belt, called the “Ring of Fire” that encircles the Pacific Ocean. Some volcanoes, like those that form the Hawaiian Islands, occur in the interior of plates at areas called “hot spots.

how do they affect the enviroment?

When volcanoes erupt, they emit a mixture of gases and particles into the air. Some of them, such as ash and sulphur dioxide, have a cooling effect, because they (or the substances they cause) reflect sunlight away from the earth. Others, such as CO2, cause warming by adding to the the greenhouse effect.

also plants are destroyed over a wide area, during an eruption. The good thing is that volcanic soil is very rich, so once everything cools off, plants can make a big comeback!

Eruptions can influence bird migration, roosting, flying ability, and feeding activity.
