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

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.
