Multiple Choice - Practice 1

In most areas of the world, certainly in Europe, both
the physical landscape and the maps of it are
relatively stable. Map revision is usually concerned
with manmade features, such as buildings and roads.
This is not true of Antarctica. The Antarctic ice sheet
is a dynamic entity and cartographers have to
contend with big and rapid changes in the physical
geography of the continent. For example, earlier this
year they faced the dramatic break-up of the Larsen
and Prince Gustav ice shelves in the Antarctic
Peninsula region, which is where the British Antarctic
Survey (BAS) concentrates its mapping activity.
Topographic maps are probably changing faster in
Antarctica than anywhere else in the world.

What do the break-up of the Larsen and Prince Gustav ice shelves illustrate?

1. The errors that occur on maps of the Antarctic.
2. The difficulties in reaching areas in the Antarctic.
3. The sort of changes that can occur in the Antarctic.
4. The regularity with which map-makers visit the Antarctic.
