Hint: Volcanic eruptions mainly lead to air pollution and water pollution. When volcanoes erupt they emit a mixture of gases and particles into the air. These gases include carbon dioxide, sulphur dioxide etc. are very harmful.
Complete Answer:
Volcano is a rupture in the crush of the earth, which allows the escape of hot lava, volcanic gases from a magma chamber which is present below the surface of the earth.
Volcanic gases which are very harmful are carbon dioxide, hydrogen fluoride and sulphur dioxide. These gases can lead to acid rain and cause air pollution. The ash which escapes from the volcano during volcanic eruption can travel hundreds to thousands of miles.
There are mainly two causes of pollution: natural causes and man-made causes.
Natural causes: volcanic eruption is a major cause for water pollution, with large eruptions volcano spew out not only lava but also ash and gases. The effects of the ash which falls from volcano to natural water increases the turbidity of water.
Man-made causes include the release of harmful gases from industries or the disposal of untreated sewage waste resulting in both air and water pollution. Disposal of sewage waste leads to many diseases such as diarrhea etc.
Hence, volcanoes are a natural source of pollution.
Note: There are many other causes of water pollution or air pollution other than volcanic eruptions such as the disposal of radioactive waste without proper treatment and the highway runoff etc. water pollution not only harms the aquatic ecosystem it also affects the groundwater.
