THE ENORMOUS FORCES OF THE ICE SHEET
Bullet-nose blocks are dragged by the ice and deposited when the ice melts.
Bullet-nose blocks can be different kinds of rock and contain important information about glaciers.
What do you see in the picture on page 44?
What can a bullet-nose block reveal?
Why is it of interest to examine the direction of the ice thousands of years after it melted away?
This model no. 4 is one of the models on page 46. There is no explaining text to the models. A plausible text to no. 4 could be this:
This model shows how the ice has crushed the large boulders.
Write a short text to the four models on page 46 like the one here explaining no. 4.
What do you see on pages 48-49?
On page 13 is a model visualizing the speed of the ice flows in Greenland. Compare the four glaciers shown.
In the picture you see one of the rivers created by the meltwater on its way to the sea.
The meltwater gathers to form rivers, cutting deep into the ice.
What happens when the melting of ice exceeds the addition of snow?
Why has there in recent years been more melting of ice than addition of new snow?
What countries would be affected if all of the ice sheet melted?
