Alpine – ice flows down the valleys of mountainous areas and forms a tongue of ice moving towards the plains below. Alpine glaciers tend to make topography more rugged by adding and improving the scale of existing features. Various features include large ravines called cirques and arêtes, which are ridges where the rims of two cirques meet.
Ice that is found at sea may be in the form of drift ice floating in the water, fast ice fixed to a shoreline or anchor ice if attached to the seafloor. [47] Ice which calves (breaks off) from an ice shelf or a coastal glacier may become an iceberg. [48] The aftermath of calving events produces a loose mixture of snow and ice known as Ice ...
Black ice on a road in Germany. Black ice, sometimes called clear ice, is a coating of glaze ice on a surface, for example on streets or on lakes. The ice itself is not black, but visually transparent, allowing the often black road below to be seen through it and light to be transmitted. The typically low levels of noticeable ice pellets, snow ...

Young ice is a transition stage between nilas and first-year ice and ranges in thickness from 10 cm (3.9 in) to 30 cm (12 in), Young ice can be further subdivided into grey ice – 10 cm (3.9 in) to 15 cm (5.9 in) in thickness and grey-white ice – 15 cm (5.9 in) to 30 cm (12 in) in thickness. Young ice is not as flexible as nilas, but tends ...
[2] [3] This ice field is the world's third largest reserve of fresh water. The Perito Moreno Glacier, located 78 kilometres (48 mi) from El Calafate , was named after the explorer Francisco Moreno , a pioneer who studied the region in the 19th century and played a major role in defending the Argentinian thesis in the 1902 Arbitral award of the ...
Ice sheets are bigger than ice shelves or alpine glaciers. Masses of ice covering less than 50,000 km 2 are termed an ice cap. An ice cap will typically feed a series of glaciers around its periphery. Although the surface is cold, the base of an ice sheet is generally warmer due to geothermal heat. In places, melting occurs and the melt-water ...
Drift ice, also called brash ice, is sea ice that is not attached to the shoreline or any other fixed object (shoals, grounded icebergs, etc.). [ 1 ] [ 2 ] [ 3 ] Unlike fast ice , which is "fastened" to a fixed object, drift ice is carried along by winds and sea currents , hence its name.
