Inside a Glacier
In Inside a Glacier, geologist Iain Stewart describes how scientists work inside an ice cave carved deep in a glacier in Norway. They learn how ice, a brittle substance, can be powerful, strong, and fluid at the same time. This video is excerpted from BBC’s Earth: The Power of the Planet, a documentary series in which Dr. Iain Stewart discovers how Earth's forces can shape nature, species, and even the climate.
Lesson Express
Q: How do scientists discover more about the glacier?
A: They tunnel inside it, create caves where they can study the ice, and use hot water to melt the interior ice.
Q: What are some examples of how strong ice is?
A: Ice can slice through solid rock; as the glacier moves along, it slices through rock and picks up sediment and carries the rock along with it as it moves.
Q: What do the ice pockets do for the glacier?
A: They make the glacier less brittle and help it flow.
