Antartica Flashcards
Antarctica climate
has the coldest climate on Earth.
Antarctica temperature
The interior averages −70°F (−57°C), while the coast averages 14°F (−10°C).
Antarctica precipitation
Antarctica’s total precipitation (mostly snow) averages ~6.5 inches (166 mm) per year, with deserts in the interior receiving less than 10 inches (~250 mm).
Antarctic rainfall
Rainfall is rare and usually occurs in coastal and island areas during summer.
Antarctica humidity
Antarctica’s dry air and low temperatures reduce humidity.
Antarctica ice sheet
The ice sheet is formed from compressed snow that rarely melts.
Antarctica winters
Winters are dark, cold, and phytoplankton-free.
Antarctica seas
Antarctic seas are productive because summer phytoplankton grows abundantly.
Antarctica krill
This massive primary-producer population supports large populations of krill.
Krill: These are key food sources in this ecosystem and serve as food for many predators.
