Where it’s Found
Deserts are found in
1. Western North America
2. Central Asia
3. Northern South America
4. Africa(The biggest desert Sahara 300 miles in
length across Africa)
5. And Australia
Map of Deserts on Earth
Human Influence
Humans influence the desert a lot.
 Off Roading( The tires make cracks in the soil and
destroy plant life and this also hurts animals because
they use plants for camouflage.)
 Irrigation( People run pipes through the ground to
supply building and homes with running water and
this takes away lots of the little water that the plants
need.)
Military Exercises( The training and target practice
often effects the animals habitats and also the camps
often destroy plant life to make and maintain.)
Landscape
The Desert has lots of landforms and an interesting a
landscape.
A. Canyons- A Canyon is a is a deep trench between
two cliffs.
B. Plateaus- A Plateaus is a mountain or elevated land
that has a flat top.
C. Oasis- An Oasis is an area of vegetation around a
water source in a desert.
D. Sand Dunes- A Sand Dune is a mount of sand
behind a sea or ocean.
These Landforms are in almost every desert on
earth.

Animals of the Desert
By: Javi Turner
Abiotic And Biotic Factors
• Biotic Factors are all the living things like
animals and plants. The way these things
effect animal life include, hunting, being
hunted, where they can live, and more.
• Abiotic factors include things like sand, major
heat, scarce water, and a few others. The way
this effects animals is the they have to adapt
to these things otherwise they might not get
enough water. Or they might overheat, die,
etc.
Examples Of Animals
•
•
•
•
•
•
•
Rhinoceroses
Elephants
Red Kangaroo
Marsh Hawk
Western Banded Gecko
Mountain Mule Dear
Spotted Hyena
Omnivore Examples
Lizards, Tortoises, Birds, and more!
Carnivore Examples
• Snakes, Coyotes, Hawks, and more!
Herbivore Examples
• Camel, Pronghorn, Javelina, and more!
Adapting to the Desert
• Animals in the dessert have to adapt. They
have to adapt to the severe heat, the sun, and
low water, and many others. Also, they have
to worry about shortage of food. To avoid day
heat, many desert animals are nocturnal, or
sleep at day and are out at night. Some
burrow underground or sit in shade during the
day. Often animals will get water out of their
food instead of drinking.
Food Chains
• Tertiary
Consumer (At the top
and feed on other
carnivores)
• Secondary
consumers
• Primary
Consumers
• Producers &
Decomposers
Food Chains
Decomposers
The groups of fungi, bacteria, insect, and
other “scavengers” that take In and break
down dead things making them usable again.
They decompose things like dead animals and
dead plants. The material is then able to be
used again. They are the last on the food
change and keep nutrients moving in the food
webs.

Definitions & Facts
•
•
•
•
•
Weather: Describes changes that happen day to day to
conditions regarding sunlight, precipitation, humidity, air
pressure, temperature, etc.
Climate: Describes the average weather conditions in a
certain place or during a certain season. Climate changes
to not occur daily but over hundreds or thousands of years
Deserts cover 20% of the worlds land
Land is classified as a desert if there is less than 10 inches
of rainfall per year
Most large deserts are found away from the coasts, in
areas where moisture from the oceans rarely reaches
Desert Biomes-Meteorologist
4 Types of Deserts
• Hot and Dry:
•
•
Parch terrain and rapid evaporation
Examples: Sahara, Saudi Arabia, Iran and Iraq, California and
South Africa
• Semiarid:
•
•
Stark temperature differences due to seasonal changes
Examples: Utah, Montana, Greenland, Russia
• Coastal:
•
•
Cooler temperatures due to off shore ocean wind
Examples: Chile, Africa
• Cold:
•
•
Ice desert due to lack of moisture in the air
Examples: Polar Regions
Desert Biomes-Meteorologist
Hot & Dry Desert Weather and Climate
•
•
•
•
•
•
Are located in subtropical climate zones which have low
humidity
These deserts are located within 35 degrees north and
south of the equator
Rainfall of less than 10 inches per year and extreme
evaporation
Sunshine 365 days a year due stable descending air and
high pressure systems
Maximum temperatures are around 120 Degrees
Fahrenheit
Nighttime temperatures can drop to freezing (32 Degrees
F) or below
Desert Biomes-Meteorologist
Semiarid Desert Weather and Climate
•
•
•
•
•
There are both cold semi-arid and hot semi-arid climates
These deserts are located all over the globe and are not
as dry as the as the Hot and Dry deserts
Nighttime condensation of dew may be higher than the
10 inches of annual rain in hot and dry deserts
Stark temperature differences from season to season
Temperatures can reach 100 degrees F in summer and
10 degrees F in winter
Desert Biomes-Meteorologist
Coastal Desert Weather and Climate
•
•
•
•
Coastal deserts lie on the western coast of Africa and South
America
These are considered coastal fog deserts who's dryness is a result
of cold ocean pressure systems and winds
Average rainfall is around 8-13 centimeters annually which is very
low
Average summer temperatures can reach 90 degrees Fahrenheit
and winter can get as low as 25 degrees Fahrenheit
Desert Biomes-Meteorologist
Cold Desert Weather and Climate
•
•
•
•
•
•
Cold deserts are located near the north and south poles
Nearly all moisture is locked up in the form of ice
Short, moist summers and long, cold winters
The summer temperatures can be as high as 39 degrees
Fahrenheit and winter temperatures can dip to -15
degrees Fahrenheit
Rainfall can be as high as 5 inches per year
Snowfall can reach 3 inches per year
Desert Biomes-Meteorologist
How Does Desert Weather Impact the Environment?
•
•
•
•
Global warming is causing deserts to grow larger
each year across the globe
Winds can also carry sand grains off the dunes and
deposit them in non desert areas. This can turn
fertile land into desert land which is another reason
deserts increase in size each year
Precipitation through rainfall and other forms of
condensation are eliminated from the environment
once they enter a desert climate
Rain is absorbed quickly into the dry ground of hot
deserts or turned ice in cold desert regions
Desert Biomes-Meteorologist
How Does Desert Climate Effect Global Weather?
•
•
•
•
Climate describes average weather conditions over
hundreds of years
Desert climates effect global weather because they
deserts are steadily growing every year
An example of desert growth is The Sahara Desert,
which grows up to 30 square miles per year
Our deserts expanding effects global climate by
raising average temperatures and making land
uninhabitable
