Glaciers can erode already susceptible mudrock formations, and this process enhances glacial production of clay and silt. The Northern Hemisphere contains 90-percent of the world's lakes larger than 500 km (310 mi), and glaciers created many of those lakes. Lake deposits formed by glaciation, including deep glacial scouring, are abundant. [4]
They contain active biological communities of extremophilic microbes that are adapted to cold, low-nutrient conditions and facilitate biogeochemical cycles independent of energy inputs from the sun. [9] Subglacial lakes and their inhabitants are of particular interest in the field of astrobiology and the search for extraterrestrial life. [10] [11]
Lacustrine deposits have gained more attention recently due to containing valuable source rocks of oil, coal, and uranium. Lacustrine deposits generally provide productive mining conditions but can prove challenging when underground mines are attempted due to the poor shear strength of clays and silts as well as the amount of moisture often locked in the layers due to a low permeability ...

Thus, more supraglacial lakes lead to a vicious cycle of more melting and more supraglacial lakes. [8] A good example is the Ngozumpa glacier, the longest glacier in the Himalayas, which counts numerous supraglacial lakes. The drainage of supraglacial lakes on mountain glaciers can disrupt the internal plumbing structure of the glacier.
Devon Energy Corp. (NYSE: DVN) is an independent energy company that primarily explores, develops, and produces oil, natural gas, and natural gas liquids (NGLs) in the United States and Canada. It ...
The Seven Rila Lakes in Rila mountain, Bulgaria, are of glacial origin. The Great Lakes as seen from space. The Great Lakes are the largest glacial lakes in the world. The prehistoric glacial Lake Agassiz once held more water than contained by all lakes in the world today. A glacial lake is a body of water with origins from glacier activity ...
Thanks to natural gas, energy stocks have been outperforming other sectors and the broader market. Year to date, the S&P 500 Energy ETF (XLE) is up more than 7%, compared to the broad-based index ...
