SubSequent effectS

Stopping off-roading will not much effect human lives, as it may take a little bit more time driving around. Careless drivers who just go straight through deserts and can not be bothered to drive around should. It will not have a massive impact on humans.

Solutions

Solutions to the humans who are influencing the desert is to not drive through them. Drive around so you do not damage our deserts. This way vegetation and plants will continue to grow keeping animals alive.

'Off Roading'
Is when a car drives off track through the desert in unrestricted areas. This impacts the desert by vehicle tracks imprinted on the ground, damaging for decades, and spoiling vegetation and the flora of the biome. When the vegetation and flora are spoiled it affects the fauna of the desert harming them and decreasing the population.

Location? Location? Location?

Deserts can be located in many places. North Africa, Australia, southern North America and the middle east contains the largest deserts. But smaller deserts are in several other places such as on the Pacific coast of South America and the atlantic coast of southern Africa. A popular desert is the Sahara desert pinpointed in North Africa. Other deserts like the Arabian desert which covers the Arabian peninsula, the Great Basin Desert is in North America. As well as the Gobi desert is in the northern and northwestern part of China and western part of Mongolia.

BiomE CharacteristicS

Characteristics of the desert: the ground is rocky/gravely, hot soils. There is barely any shade as trees and plants are low and very few. Water is hardly found and most animals are nocturnal allowing them to come out at night when it is cooler. Most live in burrows or find hideaways for them to live and sleep.


Other biomes characteristics: 

Mountains are usually very large. At the top it becomes very cold because if they are really tall it begins to reach the top of the troposphere where it becomes colder. A mountain is rocky or earthy land that has uplifted and formed into a rounded pointy sorted of way. An animal that lives on mountains is the mountain goat. 

Tundra has a very cold climate. It is a grassland with no trees. Animals who have adapted to the alpine tundra are birds, insects, mountain goats, sheep, elks and few others. To the arctic tundra arctic hares, squirrels, arctic foxes, wolves, birds, insects, polar bears and fish as well as quite a few more.

Marine includes oceans, estuaries and coral reefs. Which by now you can tell we are talking about water and what's below the surface. Under water is coral, fish, crustaceans, clams, octopuses, oysters, worms and a variety of other underwater creatures. 

The tropical dry forest biomes consist of trees. With climate being dry with high temperatures. 








Cold climate forest's water hardly evaporates causing numerous ponds, lakes and marshes. Black bears, wolves, moose, bison, lynx, deer, squirrels and various birds. Obviously the temperatures are low being cold. 

The temperate forest temperatures can range between -30˚C to 30˚C. Summers are warm and winters are cold. Tree leaves change in colour are seasons change.

Grassland summers are really hot crisping the flora to a golden brown but freezing it during winter. Reducing these lands are the animals grazing there (such as deer, bison and horses) and wildfires.

Savannahs are seasonal tropical grasslands that have many birds, lions, cheetahs, leopards, rhinos, elephants, buffalo, hippos, giraffes, zebras, gazelles and lots of others.

Flora and Flauna

Animals that live in the desert include:
                                                             1. Jackrabbits
                                                             2. Owls
                                                             3. Kangaroo Rats
                                                             4. Lizards
                                                             5. Snakes
                                                             6. Tortoises
                                                             7. Desert fox
                                                             8. And a common one that most people think of when they think of the desert biome is camels.
                        
A plant that is in the desert that would most probably first come to someones mind would be a cactus. Other plants in the different deserts are Joshua trees, thorn-covered ocotillo, sagebrush, mesquite trees and there few others. These plants can survive in the desert because they can go for a long time without water. This is because of their large root systems or/and if they have thick or waxy leaves, they are then able to contain water or live on little amounts. 

Biomes???

A biome is a region of flora and fauna that inhabits a vital habitat.

There are 9 biomes:
1. Mountains
2. Tundra
3. Temperate Forest
4. Marine/Island
5. Desert
6. Tropical Dry Forest
7. Cold Climate Forest
8. Grassland
9. Savannah
