Greenland glaciers can carry ice stones to remote edges

From Greenland to the rocks from Icegergs, many climates in Europe have been colder, from 540 years. Can have a “mini ice age” Played in the fall of the Roman Empire.
This cold northern hemisphere period has been indicated above examinations of trees and sediment nuclei. has been associated with some historical events around the worldThe collapse of the North Wei dynasty in China in Central America’s decline in Teotihuacan.

Christopher spencer In Kingston, Kingston, and his colleagues decided to explore a beach on the west coast of Iceland, showing that satellite photographs showed light than other black Basalt in Iceland.
Lighter color due to the presence of many shells, but walking in the field, Spencer saw large granite stones. For him, these rocks immediately cleaned were not Iceland. “It’s a little embarrassing to find the discovery how easy it was,” he said.
Sure enough, they reaffirmed the study of rocks that came from several parts of Greenland, which is located 300 kilometers from Iceland. This means that the rock stretch found in Greenland had had to wear the glaciers of the Greenland and was cleaned on the beach.
The layer of the beach present in the Greenlandian rock is 500. And it has been around 700 ad, says Spencer. As Greenland’s icebergs still reach this area, Greenland rocks are not found in other beach layers.

So the discovery shows that large numbers of Greenland icebergs were cleaning this beach during the time this layer was formed. This suggests that due to colder conditions, Greenland glaciers were greater and the ice were more harmful during this period, saying Spencer.
This connects the evidence of a colder period, sometimes called small old ice age. The reason for this event is not clear – they think Volcanoes turned onOthers, Comet parts of the parts of the earth. Spencer believes only to the orbital changes that affect the heat of the sun when it reaches the ground.
