Located at latitudes between 50 – 60 degrees north.
Precipitation between 35-40 cm each year.
Covered with cone bearing trees called coniferous
trees. Very similar to pine trees

Desert Biome




Driest biome on earth. Less than 25 cm of rain per year.
Located near 30 degree North and South latitude .
Animals and plants have special adaptations for survival.
Rain is quickly drained away or evaporated.
Deserts
Desert
Antarctica


It is the largest desert on earth
It is a desert because it receives less than 10”
of precipitation per year
