If you live in the northern part of the United States, you might be able to find some. Would you know what to look for? Erosion by These combined forces break up the rocks and erode the peaks into their stark, sculpted forms. Falling ice, rocks and gushing water wear away at the mountain slopes. The ice and rock debris accumulates in the valleys and flows downwards as slow moving glaciers. When these melt, piles of rock debris called moraines are left behind.

Ice cores from mountain glaciers, especially those from the tropical latitudes where most of the world's population is concentrated, provide unique and valuable archives of climate information because they are able to record variations in atmospheric chemistry and conditions. A semi-circular or amphitheater-shaped bedrock feature created as glaciers erode back into a mountain. This is where the snow and ice forming the glacier first accumulates; it is the "headwaters" of a glacier. 2011-01-21 · When glaciers began their final retreat 10,000 years ago, they left behind many landscape features, such as lakes, valleys, and mountains. Many hollowed-out areas carved by glaciers became lakes. Bowl-shaped cirques, where most alpine glaciers form, became mountain lakes.

When the main and the tributary glaciers flow at the same level, the shallower valleys created by the tributary glacier hang above the valley carved out by the main glacier. Continental Glaciers vs. Alpine glaciers Continental glaciers cover parts of continental land masses like Greenland but, Alpine glaciers are found high in mountain valleys, above the snow-line. Differences: Location; Alpine glaciers are only found on mountain tops but continental glaciers are only found at the earth's poles regardless of elevation. 2010-09-16 · These mountains are in the Patagonian Andes, the region where glaciers are protecting mountains from erosion.
