When lava meets water, for example, the results can be explosive. Understanding these interactions is vital for keeping communities who reside in hazardous zones — like the volcanic and oceanic Hawaii — safe from lava flows. Plus, it can tell us about how volcanoes might work on other planetary bodies. Here's how lava reacts to four different environmental factors.
