Transcript of Tundra
Canada in the northern
hemisphere. By Navneet
TP7 -Separated in 2 main parts which are the Arctic and Alpine Tundra -The word Tundra comes from a Finnish word "Tunturi" meaning treeless plain. -Growing season is only 6-10 weeks because the tundra is the coldest biome. -Under soil is permafrost which is a permanent layer of ice -It is very bumpy. soggy and wet when snow melts in summer -Characteristics are low biotic diversity, limit of drainage, simple vegetation structure, frozen soil, poor nutrient and low temp Climate -very cold and average would be -30 degrees -short summer and gets no warmer than 3 degrees to 12 degrees. The sun would be up 24 hours -In winter it's dark,long days and the sun
rises less -not much rainfall and snowfall in the tundra -no trees because too cold and roots will be affected by the permafrost -Climate is also a little different in different places North of Canada North of Russia Around Greenland and Info on the Alpine Tundra -located in mountain regions all around the world -cold,very windy and snowy because they are located on top of mountains -summer lasts from June to September in average temp of 10 degrees to 15 degrees -winter from October to May with temp below freezing -well drained and richer soil because there is no permafrost - many animals and plants, also growing season is 180 days long -no trees because they are on top of mountains -low temp in long cold winters -Temp drops 10 degrees every 1000 meters up the mountains in the alpine tundra -lots of different rocks and clouds in the sky -poor soil an poor nutrient because of little rainfall and permafrost -very strong wind which blows 100m per hour -melted snow forms rivers because the soil can't collect it all -water is very slow to evaporate in the tundra that's why it doesn't rain -Animals that live in this tundra are caribou, foxes, wolves, polar bears, deers, flatfish, bumble bees and etc (there are many more) -Plants that grow in the tundra are 400 different kinds of flowers, mosses, poppy, grasses, herbs and etc Biotic Elements in
the Arctic Tundra -too cold for vegetation and trees and because of the permafrost -plants have 6-10 weeks to grow and reproduce while it warm -low biotic diversity Biotic Elements in
the Alpine Tundra -Animals that live in the tundra are marmot, mountains goats, sheep's, grasshopper, chipmunks, goose like birds, butterflies, and etc -Plants that grow in the alpine tundra are wallflower, daisy, dwarf trees, grasses, willows, small leafed shrubs and etc FOOD WEB grasses lichens liverworts caribou moss pikas Musk Ox caribou Lemmings arctic hares Arctic fox Brown Bears Arctic wolves polar bears kittiwakes snowy owl Description Abiotic Elements Adaptations -Plants are adapted to the cold climate -Some plants grow in groups to keep out the cold and wind -Plants are dark and have hair to absorb solar heat -plants can grow under the snow because they are adapted to the climate Plants Animals -Some animals can camouflage and change colors from white to brown -Some animals have thick fur coats to keep them warm -The animals are adapted to the cold temp References Location Thanks for Watching Book:
