In December 1868 and then in February 1869 Ivan Khudyakov made the discovery of the Northern Pole of Cold by measuring a record temperature of −63.2 °C (−81.8 °F) in Verkhoyansk. Later, on January 15, 1885, a temperature of −67.8 °C (−90.0 °F) was registered there by Sergey Kovalik .
Blood Falls is an outflow of an iron(III) oxide–tainted plume of saltwater, flowing from the tongue of Taylor Glacier onto the ice-covered surface of West Lake Bonney in the Taylor Valley of the McMurdo Dry Valleys in Victoria Land, East Antarctica. Iron-rich hypersaline water sporadically emerges from small fissures in the ice cascades.
The South Pole is at an altitude of 9,200 feet (2,800 m) but feels like 11,000 feet (3,400 m). [34] Centripetal force from the spin of the planet throws the atmosphere toward the equator. The South Pole is colder than the North Pole primarily because of the elevation difference and for being in the middle of a continent. [35]
Visualization of the ice and snow covering Earth's northern and southern polar regions Northern Hemisphere permafrost (permanently frozen ground) in purple. The polar regions, also called the frigid zones or polar zones, of Earth are Earth's polar ice caps, the regions of the planet that surround its geographical poles (the North and South Poles), lying within the polar circles.
Blood residue are the wet and dry remnants of blood, as well the discoloration of surfaces on which blood has been shed. In forensic science, blood residue can help investigators identify weapons, reconstruct a criminal action, and link suspects to the crime. [1] Analysis of blood residue is also an important technique in archeology. [2]
A hot stain is a region of the world where safe drinking water has been depleted. [1] The term may have been coined by Goldman Environmental Prize winning hydrologist Michal Kravcik. [2] Hot stains can be found on every continent, except for Antarctica. The biggest reason for a hot stain to develop is population pressure.
Such plunges occur when the air currents that keep frigid air over the North Pole — the polar vortex — weaken, and the freezing arctic air slips south and pushes the vortex down with it.
Cold traps are some of the important places on the lunar south pole region in terms of possible water ice and other volatile deposits. Cold traps can contain water and ice that were originally from comets, meteorites and solar wind-induced iron reduction. From experiments and sample readings, scientists were able to confirm that cold traps do ...
