The Orange And Yellow Parts Show Deserts Over The World.

Map The orange and yellow parts show deserts over the world.

Abiotic Factors Sand is one of the things you can find all over the desert; there is no place you can’t find sand. Sand is tiny pieces of stone or rocks been hit into each other for millions of years in water. Stones or rocks are bigger pieces of stone or rock, stones or rocks can be found some places in the desert. Stones come from volcanoes or made naturally. There is water in the desert; it can be very deep under the ground or in the atmosphere (air).

Native Plants and Adaption

There are a lot of plants in the desert, but we only choose three, the three plants are: • Desert lily • Crimson Hedgehog Cactus • Cactus Mammillaria Desert lily is native to the deserts of southern California and western Arizona. Desert lily adapted a little. The desert lily doesn’t live that long time, but a bulb on it collects moister, so when the bulb is full it drops down on the ground and then it lives longer time. Crimson Hedgehog cactus is native to the American continent. The Crimson Hedgehog Cactus has adapted after generation to generation. It got small, and small then other cactuses, more and more pushed together. Cactus mammillaria is native to Central Mexico. Cactus mammillaria adapted like the other cactuses. Animals destroyed it because of the water it had inside, so it spines on it so the animal couldn’t destroy it.

Native Animals and how they adapted Desert Kangaroo Rat – The desert kangaroo rat can be found in the deserts of California and Arizona. It usually grows up to 38 cm including its tail, and weighs usually about 65g. It looks like a mini kangaroo and its hair above is yellow and white underneath and a white bit at the end of the tail. The

thing that sticks out with the desert kangaroo rat is that it has huge eyes. They dig holes of 1.5m. The desert kangaroo rat has adapted by digging holes in the ground for protection from predators.

Desert big horn sheep – The desert big horn sheep can be found in the deserts with Rocky Mountains. It has an excellent eye sight and can spot predators from far away. Their horns can weigh up to 14 kg. The female sheep usually known as rams weighs up to 119-127 kg and measures 160-180cm. The male sheep usually known as ewes weighs up to 53-91 kg and measures 150cm. The desert big horn sheep has adapted by having a good eye sight to spot predators.

Desert Tortoise – It can be found in the deserts of California and Arizona. It usually grows 23-38 cm and the height is 10-15 cm. It usually weighs 4-7 kg. The usually live 80 years but some has been 100 years. When the male tortoises meet they tend to start a fight, 95% of their life is spent underground. The time when their most active is in spring when flowers and plants start to grow The way it's adapted is by how it can take incredible heat.

Activities There are a lot of activities you can do in the desert. You can drive ATV (a four wheeled via call) flying up and down the sand, bus tour where you see a lot of things like trees, plants, animal, and other stuff, you can go around the desert, motorcycle (two wheeled via call) also flying

up and down the sand, and sand boarding, it’s like snowboarding but on sand instead of snow.

Biome Beside Grasslands are mostly beside desert, when you get to the end of the desert it’s just like going in to a new world. There can also be a mountain beside deserts.

Climate: is the is of

Hot. Dry, but there more to climate in desert. First, there more than one type desert. We will look

at two types of deserts. Subtropical (hot) and temperate (cold).The ranges for temperature and precipitation are shown in

the figures below.

At the higher end of this range, most of the precipitation tends to fall during one season, with the effect that water is in short supply for much of the year. It all depends on how you define a desert. The temperature range for the subtropical desert in the top left figure goes too far to the right. The temperate grassland and desert biomes outlined in the second graph are not separated; the desert part of this would be the drier part. Finally, if one inserts the woodland biome into the figure, as many ecologists do (bottom figure), the temperate grassland and desert are displaced to the colder range of the subtropical desert range. Remember that biomes are human constructs and that in nature there are not fences around each of the biomes, with little gates so you know when you are entering and leaving biomes. They grade into each other In any event, what we will call subtropical desert is fairly warm, with average annual temperatures above 10° C and precipitation up to 100 cm/year, again precipitation is less (usually much less) than 100 cm/year and average annual temperature is less than 10° C.

How we Treat the Deserts One of the biggest threats to the desert is development. When air-conditioning came people voluntarily went and lived in the desert, another reason is many people mine. Many deserts have no made mining in deserts illegal because it stopped plants in the desert from growing. Global warming from CO2 emissions is a predicted affect to the

desert biomes. It can rise the average temperature which can be an affect to animals and plants by it getting to hot for them to live there. Humans have been also a part of it by them creating firewood activities in rainforests are just causing them to make more deserts but with no desert animals which is called *desertification*.

Impact The impact of the possible climate change in the desert biomes is global warming. CO2 is the warming of the globe. This happens when gases are CO2 emissions are released into the air. CO2 is one of the main gases which produce global warming. It is said that the temperature is going to rise 6 degrees in the next 50 years.

Global Importance Deserts are important because of its high range of plants and animals living there. Two thirds of the world’s oil is also found in the desert, which is now powering must of the world. Also the desert provides a large amount of solar and wind energy.

How we worked We split the work up into parts equally so it wouldn’t be too hard for some people. We used a lot of time discussing figuring out how we would do this, the design and information.
