How was Greenland’s Grand Canyon formed? There are two possible ways. The first is that the canyon was formed by huge ice sheets. When ice sheets slowly move across the land, they scratch its surface and create deep holes. The largest lakes in the world, the Great Lakes of Canada and the United States, were formed this way. However, this theory is probably not true because the canyon is much older than Greenland’s current ice sheet.
The other way is that the canyon was formed by huge rivers in the past. For the last two million years, the world’s temperatures have gone up and down countless times. When they go up, a lot of water melts from Greenland’s ice sheet and flows into the ocean. This extremely huge amount of water carved the long, deep canyon. Later, when temperatures went down again, the river dried up and became filled with snow and ice.
