Volcano Image 4: Klyuchevskaya volcano (image #STS068-214-045)

Background for the teacher: This dramatic image shows a volcano exploding, throwing large amounts of ash and steam into the atmosphere. This volcano is in Kamchatka, the same region shown in the previous image (this volcano is just outside of the area shown in that image). 

Possible starting points for investigations:

•What is happening in the image? What is the billowing brown stuff?
•Which way is the wind blowing?
•How frequently do volcanoes explode in this region?
•How frequently around the world? (hint: try the volcano web site: http://volcano.und.nodak.edu/)
•How much do volcanoes impact on the atmosphere?
