The Snowball Earth is a geohistorical hypothesis that proposes that during one or more of Earth's icehouse climates, the planet's surface became nearly entirely frozen with no liquid oceanic or surface water exposed to the atmosphere.
Snowpack is an accumulation of snow that compresses with time and melts seasonally, often at high elevation or high latitude. [1] [2] Snowpacks are an important water resource that feed streams and rivers as they melt, sometimes leading to flooding. Snowpacks provide water to down-slope communities for drinking and agriculture. [3]
' study of ice ') is the scientific study of glaciers, or, more generally, ice and natural phenomena that involve ice. Glaciology is an interdisciplinary Earth science that integrates geophysics, geology, physical geography, geomorphology, climatology, meteorology, hydrology, biology, and ecology.
Ice dams on roofs form when accumulated snow on a sloping roof melts and flows down the roof, under the insulating blanket of snow, until it reaches below freezing temperature air, typically at the eaves. When the meltwater reaches the freezing air, ice accumulates, forming a dam, and snow that melts later cannot drain properly through the dam ...
[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 ...
Ice fields are formed by a large accumulation of snow which, through years of compression and freezing, turns into ice. Because of the susceptibility of ice to gravity, ice fields usually form over large areas that are basins or atop plateaus, thus allowing a continuum of ice to form over the landscape uninterrupted by glacial channels.
Snow angel left by a pheasant in Montana's Bowdoin National Wildlife Refuge. Some birds (e.g. pheasants) leave on the snow a figure similar to a snow angel. Weddell seals often leave outlines of themselves, similar to a snow angel, melted into the ice; additionally, these seals can thumb their nose at the cold, leaving images called seal shadows.
Kosuke enlightens Daisuke with the story of "Ice and Snow". Daisuke completes his piece for the festival - a painting of a snowscape, where the shadows on the purest snow are blue instead of gray. Mio must make a very important decision. As Riku gives Daisuke the pendant of friendship instead of love, Mio sacrifices herself in the end.
