Hoe dik is de ijskap op Groenland?
De hoeveelheid ijs op Groenland en Antarctica is natuurlijk nog steeds enorm. De ijskappen zijn gemiddeld zo’n 3 kilometer dik en die zijn niet zomaar verdwenen. Wetenschappers hebben berekend dat als al het ijs van Groenland zou smelten dat wereldwijd de zeespiegel gemiddeld zo’n 7 meter zal stijgen.

In Antarctica, the lack of flowing water makes snow your primary source of water, be it for nutrition or hygiene.
How do Antarctica’s stations get freshwater?
Getting freshwater in Antarctica is difficult and time consuming. Each station obtains fresh water by different means. In earlier days, snow and ice was shovelled into large tanks and heated to melt into water. Today, Casey and Mawson pump water from a melt lake behind the station and store it in a heated tank house.
What is the weather like in Antarctica?
With temperatures perpetually at below zero, the snow and ice in Antarctica are on a constant freeze throughout the year, regardless of the season. The coastal region of the continent is warmer, with temperatures ranging between -20 °C and -30 °C. Due to the freezing temperatures, Antarctica is the remotest place on the planet,…
What are the winds and currents of the Antarctic Ocean?
Some of these winds and currents include the Polar Front, the Antarctic Convergence, and the Antarctic Circumpolar Current. The ocean is characterized by upwelling caused by westerly winds blowing around the continent. The upwelling brings up waters from the ocean’s depths which is usually cold.
