Biogeography of the Ice Age: video worksheets, differentiated.

More biology resources here, and geography here.

A very detailed, thorough, and engaging review of the planet’s changing biogeography throughout the recent Ice Ages. The film describes the relationship between temperature and humidity, and its consequences during glacial minima; the extent and biodiversity of the Mammoth Steppe. Polar, alpine, and tropical deserts. Equatorial climates relatively unchanged – a refuge, eventual dispersal; the Panama Isthmus, the Great American Interchange. Deglaciation – forests move northwards. Africa – small tropical rain forests, Mediterranean forests and steppe. India and the Sunda rainforest, Indomalaya and The Wallace Line; Sahul. Antarctica – fossil data buried under ice. Extinctions of megafauna. Plenty of stats shown in easily-understood graphics, excellent animations of continental drift and sea-level changes. Good subtitles, scripted, not auto-generated, but with one or two typographic errors.

Find the film by searching YouTube’s Atlas Pro channel for “The BIOGEOGRAPHY of the Ice Age”. My link omits a brief trailer at the end, the film will stop straight after my sheet’s final question if you use my embedded link.

14 questions for the 13-min film (not inc. the omitted trailer). Differentiated! Both versions look very similar, but “B” version has subtle clues. Questions right up to the end (of my embedded link), no slack time! Answer sheet. Very easy to mark. .doc & .pdf for all files.
