Antarctica is surrounded on all sides by the Southern Ocean. As a result, high-speed winds circle around Antarctica, preventing warmer air from temperate zones from reaching the continent. While Antarctica does have some small areas of tundra on the northern fringes, the vast majority of the continent is extremely cold and permanently frozen.
Color vision is categorized foremost according to the dimensionality of the color gamut, which is defined by the number of primaries required to represent the color vision. This is generally equal to the number of photopsins expressed: a correlation that holds for vertebrates but not invertebrates .
Nearly all of Antarctica is covered by a sheet of ice that is, on average, at least 1,500 m (5,000 ft) thick. Antarctica contains 90% of the world's ice and more than 70% of its fresh water. If all the land-ice covering Antarctica were to melt — around 30 × 10 ^ 6 km 3 (7.2 × 10 ^ 6 cu mi) of ice — the seas would rise by over 60 m (200 ft ...
Today, among simians, the catarrhines (Old World monkeys and apes, including humans) are routinely trichromatic—meaning that both males and females possess three opsins, sensitive to short-wave, medium-wave, and long-wave light [4] —while, conversely, only a small fraction of platyrrhine primates (New World monkeys) are trichromats.
A speculative representation of Antarctica labelled as ' Terra Australis Incognita ' on Jan Janssonius's Zeekaart van het Zuidpoolgebied (1657), Het Scheepvaartmuseum The name given to the continent originates from the word antarctic, which comes from Middle French antartique or antarctique (' opposite to the Arctic ') and, in turn, the Latin antarcticus (' opposite to the north ').
Single-digit temperatures and below-zero wind chills are nothing to take lightly when forced out into arctic winter weather that has been sweepin the country.
A five-month-long slumber party. A college dorm. An introvert’s hell. Those are just some of the words residents of Antarctica use to describe life in the world’s coldest, most mysterious ...
The blue color is sometimes wrongly attributed to Rayleigh scattering, which is responsible for the color of the sky. Rather, water ice is blue for the same reason that large quantities of liquid water are blue: it is a result of an overtone of an oxygen–hydrogen (O−H) bond stretch in water, which absorbs light at the red end of the visible ...
