When Greenland is white and ice-covered, why is it called Greenland?
<|assistant|>
Greenland got its name because the Vikings who settled there believed that the island was full of grass and trees, which was how they referred to any land that was not covered in snow or ice. As their settlements and their tales of the island spread, Europe began to use the name "Greenland" for the country. But as the settlements failed and the island became more and more covered in ice, the name no longer fit. Today, only a small portion of Greenland is actually covered in snow. The bulk of the island is full of rock, scrub and mosses, giving it its namesake greenlandic color.
