Fill in the blanks to describe the work of Ben Kennedy, a volcanologist who works in New Zealand.

Question

To learn more about why his pumice sample was shrinking, Ben Kennedy studied
.

This material is similar to pumice because both are full of air
.

Kennedy found that the shrinking had to do with molten rock’s surface
, which is the force that holds a droplet of water together.

Answer 1

To learn more about why his pumice sample was shrinking, Ben Kennedy studied the properties of volcanic gases and their interactions with the surrounding environment.

This material is similar to pumice because both are full of air bubbles that form during volcanic eruptions.

Kennedy found that the shrinking had to do with molten rock’s surface tension, which is the force that holds a droplet of water together.
