How volcanoes effect flora and fauna?

Answer 1

How Volcanoes Influence Climate Over Shorter Timescales

effect on climate. For the most part they cool the planet by shading incoming solar radiation. This affect can last for months to years, depending on the characteristics of the eruption. Eruptions in the tropics can have an effect on the climate of both hemispheres. Volcanic eruptions at mid or high latitudes only have an effect on the hemisphere they are within. Volcanoes have also caused global warming over long geologic time scales when extreme amounts of volcanism occurred.

Particles of dust and ash

Volcanic dust (ash) released into the atmosphere during volcanic causes temporary cooling. Larger particles have little effect because they fall out of the air quickly. Small ash particles in the troposphere form a dark cloud that shades and cools the area directly below. These particles will fall out of the atmosphere in rain a few hours or days after the event. The dust that causes the most cooling is that which gets into the stratosphere. It can stay in the stratosphere for months, blocking sunlight and causing cooling over large areas of the Earth.
