Cold environments
,Polar
• Regions of the world covered by ice most of the year. Includes large
portions of the Artic and Antarctic. A polar ice cap or polar ice shee
a high-latitude region that is covered in ice
• Ice cap is <50,000Km2 ice sheet is more
• E.g. Greenland and Antarctica
,Tundra
• Regions found south of the ice caps in the northern hemisphere.
Tundra regions are vast, flat, treeless areas where the subsoil is
permanently frozen.
, Climate – McMurdo Antarctica
(polar)
• Summer (dec/jan) • Plants and flowers must seed quickly
• Av temp = -3 • E.g. artic grass
• Av precipitation 2mm
• Polar bears have thick layer or fur, 10cm insulti
small ears and black foot pads and nose to abso
• Winter (June/July) heat. Move slowly and res to avoid over-heatin
fur camouflages and hoof claws for hunting and
• Av temp = -23 digging.
• Av precipitation 2mm
• Snowshoe hairs have big feet to spread their w
and move quickly across the snow and white fu
winter camouflage
