Volcano Image #2: Java, Indonesia (image #STS046-90-029)

Background for the teacher: Each of the white patches is clouds forming around a volcano. As your students pursue their investigations, they will learn that this line of volcanoes formed as a result of Earth's plate tectonics. Over the course of millions of years, a surface plate has moved over a subsurface hot spot. Periodically the hot spot would erupt through the surface, forming another volcano. Since the plate moves but the hot spot doesn't, the result is a line of volcanoes. 

Possible starting points for investigations: 

•What are the white patches?
•Why do the form in a line?
•Cross reference with a map to learn about the physical features of Java. 
•Why are the volcanoes in a line?
