The snow of glaciers in the central Andes melted rapidly due to a heatwave, [14] increasing the proportion of darker-coloured mountains. With alpine glacier volume in decline, much of the environment is affected. These black particles are recognized for their propensity to change the albedo – or reflectance – of a glacier.
Iceland is of volcanic origin with the landscape being influenced by water and wind erosion, abrasion and frost action. The Highlands form a plateau some 500 m (1,640 ft) above sea level, lying in the central and southeastern part of the island, and occupy about 40% of the landmass; they consist largely of volcanic deserts interspersed with glaciers.

Permafrost temperature profile. Permafrost occupies the middle zone, with the active layer above it, while geothermal activity keeps the lowest layer above freezing. The vertical 0 °C or 32 °F line denotes the average annual temperature that is crucial for the upper and lower limit of the permafrost zone, while the red lines represent seasonal temperature changes and seasonal temperature ...
The main glacier erodes a deep U-shaped valley with nearly vertical sides, while the tributary glacier, with a smaller volume of ice, makes a shallower U-shaped valley. Since the surfaces of the glaciers were originally at the same elevation, the shallower valley appears to be 'hanging' above the main valley. Often, waterfalls form at or near ...

Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal wetlands, lagoons ...
