(Natural News) The ice sheet in Greenland is melting, but it turns out that the culprit is not global warming, as some people would like to have you believe. Instead, researchers have now found proof that a hidden heat source deep inside the planet is behind this melting that is pushing glaciers into the ocean…..Read more
If you’re planning a trip to Iceland, don’t miss out on visiting the incredible ice caves. The mesmerizing caverns were formed within a glacier and most are formed by water running through tunnels in the ice or on the ground beneath the glacier.
According to Iceland Photo Tours, the water likely originates on the glacier’s surface through melting. The heat transfer than creates an air-filled cavity. Over time, movement of the warm air enlarges the cave through melting in the summer and sublimation in the winter.
It is also likely the ice caves formed as a result of geothermal vents or hot springs underneath the ice. Because the glaciers are constantly moving, the ice caves are not permanent. Additionally, the solidness of certain caves varies, making some less safe than others. For this reason, it is recommended to explore an ice cave on a guided tour.…
