Globes usually have a geographic coordinate system and a scale.
It makes the von thunen model almost obsolete because anything can be transported to anywhere.<span />

The great continental glaciers of the last ice age were melting away around <u>15,000</u> years ago.
Continental glaciers are continuous ice masses much larger than those of the Alps. Small continental glaciers are called ice fields. Large continental glaciers are called ice sheets. Greenland and Antarctica are almost completely covered by ice sheets up to 3500 m (11 500 ft) thick.
Glaciers move by internal deformation of ice and sliding over underlying rocks and sediments. Internal deformation occurs when the glacier's weight and mass spread due to gravity. Slippage occurs when a glacier slides over a thin layer of water at the bottom of the glacier.
