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.

Desert Biomes-Meteorologist Owen Richardson 3/16/15

Desert Biomes-Meteorologist 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 Coas tal 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
