The hatched areas were affected by wet conditions or flooding, and the dotted areas by drought or dust storms. [1] The 4.2-kiloyear (thousand years) BP aridification event (long-term drought), also known as the 4.2 ka event, [2] was one of the most severe climatic events of the Holocene epoch. [3] It defines the beginning of the current ...
K2, at 8,611 metres (28,251 ft) above sea level, is the second-highest mountain on Earth, after Mount Everest at 8,849 metres (29,032 ft). [3] It lies in the Karakoram range, partially in the Gilgit-Baltistan region of Pakistan -administered Kashmir and partially in the China -administered Trans-Karakoram Tract in the Taxkorgan Tajik Autonomous ...
The year 2000 problem, also commonly known as the Y2K problem, Y2K scare, millennium bug, Y2K bug, Y2K glitch, Y2K error, or simply Y2K, refers to potential computer errors related to the formatting and storage of calendar data for dates in and after the year 2000. Many programs represented four-digit years with only the final two digits ...
Axial precession. Precessional movement of Earth. Earth rotates (white arrows) once a day around its rotational axis (red); this axis itself rotates slowly (white circle), completing a rotation in approximately 26,000 years [1] In astronomy, axial precession is a gravity-induced, slow, and continuous change in the orientation of an astronomical ...
v. t. e. The Universal Transverse Mercator ( UTM) is a map projection system for assigning coordinates to locations on the surface of the Earth. Like the traditional method of latitude and longitude, it is a horizontal position representation, which means it ignores altitude and treats the earth surface as a perfect ellipsoid.
Gameplay. The game is played on a stylized map of Earth. At the start of the game, a series of exploration markers are placed face-down on each of the land regions of the board, and each player begins with two small settlements, consisting of a town, a settler unit, and a swordsman unit, on a land region of their choosing (in the advanced rules, each player also begins with one technology).
A "selfie" photograph, shortly after launch by the Juice monitoring camera 2 (JMC2), with Earth in the background An ice-penetrating radar working at frequency of 9 MHz (1 and 3 MHz bandwidth) emitted by a 16 m (52 ft) antenna; will be used to study the subsurface structure of Jovian moons down to 9 km (5.6 mi) depth with vertical resolution up ...
The map suggests the universe is slightly older than researchers expected. According to the map, subtle fluctuations in temperature were imprinted on the deep sky when the cosmos was about 370 000 years old. The imprint reflects ripples that arose as early, in the existence of the universe, as the first nonillionth of a second.
