Question

How do volcanic eruptions affect the climate?

Answer 1

Volcanic eruptions can throw HUGE amounts of ash into the air, which then circulates around the planet on the prevailing currents. This ash can block out sunlight for long periods of time. Look up the explosion of Krakatoa back in the late 1800's; apparently the ash caused droughts and cold summers and also spectacular sunsets planet-wide that year.

Answer 2

they let out gasses that deplete ozone its nature NOT US!!

we dont really do anything to our air, like global warming doesnt exist no matter wat people tell you.

Answer 3

Sulfur dioxide gets into the upper atmosphere and can filter out sunlight, so the planet cools.  After Tambora in Indonesia blew in the early 1800's there followed the year without any summer...crop failures all around the world, starvation, economic collapse.  Krakatoa blew in 1883 (?) it cooled the world too but because it was MUCH smaller than Tambora the world economy, and agriculture, did not collapse.  When Pinatubo blew in the early 1990's the world got pink sunsets for about a year.

Answer 4

volcanic eruptions throw ash and earth into the air which block sunlight allowing cooling of the earth or volcanic winter.
