Ganymede's surface, like Europa's, is heavily tectonized yet appears to have few cryovolcanic features. [31] By 2009, at least 30 irregularly-shaped depressions (termed paterae) were identified on Ganymede's surface from Voyager and Galileo imagery. The paterae have been hypothesized by several teams of planetary scientists as caldera-like ...
Currently, cold surface bodies of liquid are found on two worlds in the Solar System, Earth and Saturn's moon Titan. [1] Earth is the only planet with liquid water on its surface. The other "oceans" are found under thick covers of surface ice. If both liquid and frozen water are counted, Earth ranks fifth in volume of its oceans. [2]
Ablation Valley, also known as Ablation Bay, is a mainly ice-free valley on the east coast of Alexander Island, 3 km (1.9 mi) long, which is entered immediately south of Ablation Point, opens on George VI Sound and lies immediately north of Ganymede Heights.
Thursday's weather will feature an Arctic blast for the Midwest and Northeast and still more lake-effect snow for the Great Lakes. Cold air associated with a high-pressure area will move over the ...
How lake-effect snow forms. Lake-effect snow, which can last for only a few minutes to several days, develops from narrow bands of clouds that form when cold, dry arctic air passes over a large ...
After a few days break, bitter Arctic cold will overspread much of the north-central U.S. Wednesday, while the East Coast sees heavy rain and thunderstorms from a potent storm. The Arctic air will ...
Energy flows on Titan lead to both a greenhouse effect and an anti-greenhouse effect.. Titan receives just about 1% of the amount of sunlight Earth does. [1] The average surface temperature is about 90.6 K (-182.55 °C, or -296.59 °F). [2]
Lake Effect snow happens when cold air moves across the open, unfrozen waters of the Great Lakes, creating narrow bands that produce 2 to 3 inches of snow per hour or more.
