For instance, blue lakes mostly occurred in sparsely populated, mountainous areas. What the researchers described as yellow lakes mostly appeared in forested areas, where water had high CDOM values. Lakes that were classified as green or green-yellow were more likely in areas with farms nearby.
That is because farms often produce high levels of nitrogen and phosphorous runoff that fuel algae growth, which can turn water green. Story by Adam Voiland. View this area in EO Explorer. Fine particles of pulverized rock absorb and scatter sunlight in ways that can give water a striking blue-green color. Image of the Day Snow and Ice. Long and short. Deep and shallow. Salty and fresh.
Blue and brown. Sorry, glacial flour? Is there a time of year the lake may appear brighter than other times? You may also be interested in ExploreCHC This place is a vast treasure trove of landscapes and experiences.

Glaciers move through rock and soil as they carve their way down a slope. This means the ice is going to have a lot more ingredients than just water. What would happen if you broke off a big chunk of ice from a glacier and put it in your glass of water?
Would it be any different from the ice in your freezer at home? What would happen to all those air bubbles that have been trapped under pressure? Review Questions some of the answers may come from the vocabulary list. Glacier ice is highly pressurized. Bubbles in glacier ice get squeezed and pushed around. Sometimes you can see round bubbles that have been squeezed into long rods or flat plains. Coarse-bubbly ice looks whiter than most other ice because it is filled with small bubbles.
This kind is usually found near ablation areas of a glacier. Coarse-clear ice is free of bubbles and is the bluest ice of all. This kind is usually found near the margins and terminus of a glacier. Look at ice cubes formed in your freezer. These ice cubes first froze on their outsides and trapped air bubbles toward the center. As a result, the exterior is bubble-free while the interior has bubbles. Bubbles between the outside and the inside of the cube are probably longer and more extended.
