Photograph showing details of an ice cube under magnification. Ice I h is the form of ice commonly seen on Earth. Phase space of ice I h with respect to other ice phases. Virtually all ice in the biosphere is ice I h (pronounced: ice one h, also known as ice-phase-one).
Ice is abundant on the Earth's surface, particularly in the polar regions and above the snow line, where it can aggregate from snow to form glaciers and ice sheets. As snowflakes and hail, ice is a common form of precipitation, and it may also be deposited directly by water vapor as frost.
Ice particles can have a significant effect on cloud dynamics. They are known to be important in the processes by which clouds can become electrified, which causes lightning. They are also known to be able to form the seeds for rain droplets. It has become clear that the concentration of ice nucleating particles in shallow clouds is a key ...
' 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 .
The event took place during the last gasp of the Little Ice Age, one of the coldest periods on Earth in the past 10,000 years. ... the crater formed after a massive eruption between 1700 and 1900 ...
Glacier ice is slightly more dense than ice formed from frozen water because glacier ice contains fewer trapped air bubbles. Glacial ice has a distinctive blue tint because it absorbs some red light due to an overtone of the infrared OH stretching mode of the water molecule. (Liquid water appears blue for the same reason.
The Snowball Earth is a geohistorical hypothesis that proposes 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.
Glaciers form where the accumulation of snow and ice exceeds ablation. The area in which an alpine glacier forms is called a cirque (corrie or cwm), a typically armchair-shaped geological feature, which collects snow and where the snowpack compacts under the weight of successive layers of accumulating snow, forming névé.
