These ice cauldrons "are created by melting at subglacial geothermal areas". [5] The meltwater accumulates in lakes "under the cauldrons until it drains every 2–3 years in a jökulhlaup" of normally up to 2,000 m 3 /s (71,000 cu ft/s). [4] An unusually big outburst flood (jökulhlaup) was recorded in 2015.
[citation needed] Snow and ice have much lower thermal diffusivities than air. Thermal diffusivity is a measure of the speed at which temperature waves can penetrate a substance. Snow and ice are many orders of magnitude less efficient at diffusing heat than air. Snow cover insulates the ground surface, and sea ice insulates the underlying ...
A Bronze Age cauldron, and flesh-hook, made from sheet bronze. The Holy Grail of Arthurian legend is sometimes referred to as a "cauldron", although traditionally the grail is thought of as a hand-held cup rather than the large pot that the word "cauldron" usually is used to mean. This may have resulted from the combination of the grail legend ...
The term caldera comes from Spanish caldera, and Latin caldaria, meaning "cooking pot". [6] In some texts the English term cauldron is also used, [7] though in more recent work the term cauldron refers to a caldera that has been deeply eroded to expose the beds under the caldera floor. [6]
Articles relating to cauldrons, large pots for cooking or boiling over an open fire, with a lid and frequently with an arc-shaped hanger and/or integral handles or feet. There is a rich history of cauldron lore in religion, mythology, and folklore.
Glacial pothole in Bloomington on the St. Croix River at Interstate State Park, Wisconsin, U.S.. A giant's kettle, also known as either a giant's cauldron, moulin pothole, or glacial pothole, is a typically large and cylindrical pothole drilled in solid rock underlying a glacier either by water descending down a deep moulin or by gravel rotating in the bed of subglacial meltwater stream.

Ski wax enhances the ability of a ski (or other runner) to slide over snow by reducing its coefficient of friction, which depends on both the properties of the snow and the ski to result in an optimum amount of lubrication from melting the snow by friction with the ski—too little and the ski interacts with solid snow crystals, too much and ...
The snow does not melt slower gradually with distance from the trunk, but rather creates a wall surrounding snow-free ground around it. According to some of sources, North American spring ephermal plants like spring beauty ( Claytonia caroliniana ), trout lily ( Erythronium americanum ) and red trillium ( Trillium erectum L.) benefit from such ...
