Transcript of Facts about desert, Tundr, Grassland, Rainforest, Marine Salt/Fresh Water biomes


The tundra biome is considered a carbon dioxide sink because it stores more carbon dioxide than it gives off.
The tundra biome is the largest of all the biomes. It covers about 20% of the Earth.
During the summer, it is daylight 24 hours a day.
Around 70% of the Earth’s surface is covered by oceans.
The world’s oceans contain enough water to fill a cube with edges over 1000 kilometres (621 miles) in length.
Ocean tides are caused by the Earth rotating while the Moon and Sun’s gravitational pull acts on ocean water.
While there are hundreds of thousands of known marine life forms, there are many that are yet to be discovered, some There are a lot of oil mines and oil rigs in the tundra biome, which often disturbs the sensitive nature of the environment.
There are about 1,700 kinds of plants in the arctic and subarctic tundra. The growing seasons are short and most plants reproduce by budding and division rather than sexually by flowering.
The word tundra comes from the Finnish word tunturia, which means treeless land.
Earth’s desert biomes cover more than one third of its land area.
Desert biomes are the most arid of all biomes.
Soils often have plenty of nutrients because they only need water to become very productive, and they have little or no organic matter.
A desert only gets 10 % of the amount of rain that a rainforest gets.
Most deserts receive about 250 mm of rainfall per year.
Some plants have seeds that can stay dormant for a long period of time, until rainfall is available
There are very few large mammals in the desert because most of them can’t live with scarce amounts of water and very hot climate conditions.

115 days is the lifespan of the Blue Morpho butterfly. It travels through all layers of the rainforest and has been seen in the sky by pilots.
The number of tree species a single hectare of rainforest can contain is 200.
It takes 10-15 years from finding a medicinal plant in the rainforest, identifying its uses, and get patented as a drug.
70% of anti-cancer plants identified so far come from rainforests.
30 million people live in the Amazon rainforest.
Rainforests are forests that experience a high level of rainfall.
Scientists believe that there may be millions of plant and insect species in rainforests that have yet to be discovered.
Over 25% of natural medicines have been discovered in rainforests.
Rainforests used to cover 14% of the Earth’s surface but due to deforestation now only cover around 6%.
A wide variety of animals live in rainforests, including birds, snakes, insects, jaguars, cougars, chameleons, turtles, frogs, and many more.
There are two types of rainforest, temperate and tropical.
Temperate rainforests lie in the temperate zones (between the tropics and the polar circles) of the globe. They are found in a few regions scattered around the world such as western North America, south-eastern Australia and New Zealand.
Tropical rainforests lie in the tropics (around 28 degrees north or south of the equator). They are found in many areas near the equator such as Asia, Africa, Central America and the Pacific Islands.
The Amazon rainforest is the largest tropical rainforest in the world. Read more Amazon rainforest facts.
A number of tribes in areas such as central Africa and Brazil still live in rainforests, having no contact with the outside world.
Australia has 3 parts divided into three parts according to the dominant Biome each part has.
The middle part is a Desert, the inner core has a Savanna biome, and the outer part, where Sydney is located, has a Tropical Biome.

FaunaFairy Penguin: These cute little birds live only has an average lifespan of 7 years.Red Kangaroo FF: They are the most hated animals by farm owners in Australia ‘coz they obliterate them when they feed on them.Koala FF: Koalas, when frightened, make loud, annoying noise.
FaunaBanded Hare Wallaby: Mother wallabies have extra pouches in case a friend wallaby dies.Amputa (DasycercusHillieri):
They hate the summer sun and come out only during the warm winter days.
Eastern Barred Bandicoot: These animals go on a diet with feeding preferences such as moths and beetles.
FloraDesert Oak: This tree houses the Australian Princess Parrot.
Eucalyptus: Few animals feed on this because when they do so it releases a gooey sap.Cabbage Palms: It is the official City Tree of Florida and South Carolina.
FloraPencil Pine: Although it seems like it, Pencils are not made from these.Bunya Pine FF: When seen from atop, resembles Pineapples.Boab: During the 1890s in Australia some used these to imprison slaves.

The world’s oceans contain enough water to fill a cube with edges over 1000 kilometres (621 miles) in length.
Fish supply the greatest percentage of the world's protein consumed by humans
Ocean tides are caused by the Earth rotating while the Moon and Sun’s gravitational pull acts on ocean water.
The longest continuous mountain chain known to exist in the Universe resides in the ocean at more than 40,000 miles long
While there are hundreds of thousands of known marine life forms, there are many that are yet to be discovered, some scientists suggest that there could actually be millions of marine life forms out there.
Oceans are frequently used as a means of transport with various companies shipping their products across oceans from one port to another.
The Pacific Ocean’s name has an original meaning of ‘peaceful sea’.
Most of the world's major fisheries are being fished at levels above their maximum sustainable yield; some regions are severely overfished
The longest river in the world is the Nile River, it reaches around 6650 kilometers in length (4132 miles). More Nile River facts.
The second longest river in the world is the Amazon River, it reaches around 6400 kilometres in length (4000 miles). More Amazon River facts.
Most of the world’s major cities are located near the banks of rivers.
The Ganges, Yangtze and Indus rivers are three of the most polluted on Earth.
