Desert Biome in Africa/Asia
By T.J. Lohden, Eric Harper, Jade Burgess, and Tyler Williams
The Weather
• The desert is a harsh environment with very little rainfall and extreme temperatures.
Rainfall
• A desert is defined as a region that gets less than ten inches of precipitation per year.
Lut Desert
• One of the driest deserts in the world is the Lut Desert in Iran.
• This desert gets less than half an inch of precipitation per year.
Temperatures
• Temperatures exhibit daily extremes because the atmosphere contains little humidity to block the Sun’s rays.
• Annual temperatures range from 68°F-77°F.
• Extreme maximum ranges from 110.3°F-120.2°F.
Cold Deserts
• The Gobi Desert in Mongolia is an example of a cold desert.
• Shares the very cold winters of central Asia.
Namib Desert
• Summer is very hot and the Namib Desert should be avoided at this time as temperatures are often above 104ºF.
Sahara Desert
• The world’s largest desert.
• Covers most of Northern Africa with over 9,000,000 square kilometers (3,500,000 sq mi).
Areas and Attractions in the African Desert
• 1. Barchans sand dunes • 2. Dry steam drainage • 3. Richat structure • 4. Lake Chad • 5. Jebel Marra Volcano • 6. Sand dunes • 7. Suez canal• 8. Complex sand dunes • 9. Nile Delta • 10. Atlas mountains • 11. Pyramids at Abusir
Areas and Attractions in the Asian desert
• 1. Sand dunes over a hundred meters high some over 300
• 2. There are over 80 types of birds and other species
• 3. Talkman desert • 4. Tie man pass• 5. Lop Nur people village
Animals of the Deserts
• Animals include:
• Hedgehogs
• Sidewinders
• Desert Owls
• Bats
• Fennec Foxes
• Dromedary Camels
• Dama Gazelles
• Addax
• Scorpions
• Roadrunners
Scorpions
• Scorpions hide under rocks to keep cool during harsh desert days.
• Scorpions only release a very small amount of venom with their sting, but it can be very potent.
• Scorpions are very territorial with other scorpions, but often prefer to run from very large predators.
• Stinging is a last resort, as venom takes some time to concoct.
Ostriches
• Ostriches live on the outskirts of the Saharan Desert.
• Ostriches are the second fastest land animal, with a speed of 40mph. They can keep this speed for about 20 minutes.
• Ostriches do not bury their head in the sand. Ostriches stretch out their neck and lay their head on the ground to
keep from being seen.
Kangaroo Rats
• Kangaroo Rats burrow deep into the sand to stay cool.
• Kangaroo Rats have the amazing ability to convert food they eat into water.
• Kangaroo Rats do not pant or sweat like most animals to keep cool.
• This cactus has a very thick stem.
• The leaves of the Peyote Cactus reduce to spines, this helps in preventing water loss
Peyote Cactus
• The date palm is the most important export from the Sahara desert
• Key food source for the locals
• Most meals and drinks include the fruit of the Date Palm
Date Palm
• Olive trees were first in the African Desert then moved all over the world
• Key business for the natives
• Very important to the Sahara Deserts ecosystem
• Found near the Nile River
