Extreme enviroments

  • In this presentation I’m going to talk about three extreme environments that are completely different. These environments are extreme, and we are not very adapted to that environments
  • The North Pole
  • The amazon (rainforest)
  • TheSahelianAcacia savanna

The north pole

  • Location:
  •  It's located at 90° North latitude and all lines of longitude converge at the pole. The earth's axis connects the north and south poles, as its the line around which the earth rotates.
  • The North Pole is about 450 miles (725 km) north of Greenland in the middle of the Arctic Ocean - the sea there has a depth of 13,410 feet (4087 meters). Most of the time, sea ice covers the North Pole but recently, water has been sighted at the exact location of the pole.
  • Climate
  • The North Pole is substantially warmer than the South Pole because it lies at sea level in the middle of an ocean (which acts as a reservoir of heat), rather than at altitude in a continental land mass.
  • Winter (January) temperatures at the North Pole can range from about −43 °C to −26 °C ,). So as it’s a very difficult climate to survive in, not too many living things will survive there, only those adapted to the north pole.

The north pole

  • Fauna:
  • The animalsthatyou can find in the north pole are animalsadapted to thatclimate and flora…
  • The animalsthatyou can find in the north pole are:
  • The articfox
  • The polar bear
  • The ringedseal
  • Articterns
  • Artichares
  • Snow owl
  • Animalsthatlive in water:
  • whale

The north pole

  • Flora:
  • The flora thatyou can find in the north pole are none, becauseplants are notadapted to suchlowtemperatures, and theyneedsoil, and as most of it is all ice, theycan’tsurvive, that’swhythe flora thatyou can find is only in the sea.
  • People
  • No-onelives in thenorthpole, onlyscientists, orgroupshavebeen in thenorthpole forstudyingit. Most of thepeople come fromtheUK and the USA

The amazon (rainforest)

  • Location:
  • The amazon rainforest is found in South America in the upper part of Brazil, in the southern hemisphere, very close in the equator.
  • Climate
  • The amazon rainforest has a tropical climate; it is hot and humid with an average temperature of 26 degrees Celsius all through the year. This is because it is very close to the equator, it doesn’t change very much the climate.
  • Flora:
  • The Amazon rainforest has a huge live collection of flora species. Botanical experts say that in 2.5 acres of the forest you can find 700 different species of trees and twice that number of plants. One of the most awesome things you will notice is that the forest has a high density of trees and they are very tall. Many trees reach 130 meters high

The amazon (rainforest)

  • Fauna:
  • In the amazon you can find lots of different animals, some of them are:
  • The jaguar
  • Thevampirebat
  • The tapir
  • The anaconda
  • Theleafcutterant


People live in the amazon rainforest, lots of tribes and lots of different ethnic groups.

These people are adapted to that climate because they have been living there for such a long time that now they have adapted. They are adapted to eating tropical food, living in a tropical climate, building their own houses …


Thesahelian acacia savanna


The SahelianAcacia savanna, it’s found in the northern hemisphere, in the continent of Africa and it passes through lots of countries from Africa in the north.


The Sahelian climate is a tropical semi-arid climate with the dry season mainly (but not exclusively) during the "cold" season (the coldest six months of the year):

It is tropical because the mean monthly temperature of the "coldest" month is equal to or greater than 18°C.

It is semi-arid because of low annual precipitation, below about 600 mm in a tropical climate (and above about 100–150 mm), characterized by irregular and unpredictable short rainy seasons through the years. The dry season generally lasts from about 8 to 11 months a year.

Though erratic, the rainy season in a Sahelian climate zone usually occurs during the warm season but not during the very hottest months.



The savanna is mostly covered by grass and bushes. But you can also find trees like the baobab, the acacia tree, The Candelabra Tree.



  • In the Sahelian Acacia savanna you can find lots of different animals, but most of them are really dangerous and wild. Some of them are these ones:
  • The Lion
  • The giraffe
  • The Snake
  • Theescorpion
  • The ñu
  • Therhino
  • The elephant
  • The jaguar and more…


Yes people do live in theSahelian Acacia savanna. Theylivetherebecause Africa is growing, and theyhave to findsomewhere to live, obviouslymost of them are poor, becausetheycan’tpayfor a house.

Thesepoorpeoplehaveto walklots of kilometers to findsomefood and somewater to survive, and yettheylook as thoughtheywereliving in the U.S.A.



  • Ifwe compare eachenviromentbetweenthem, we will get complete differentresults.
  • Forexample: Thenorth pole is extreme becauseit has verylowtemperatures, wecannotfindanyplantsorfood to feedourselves, and it is verydifficult to killan animal forfeedingyourself, withoutbeinghurt. However, in theSahelian Acacia savanna, there is a veryhotclimateforsurviving, so youneedlots of water, somethingthatthereisn’t in thatsavanna, and youhave to walkkilometersifyou are lucky to findsome. Alsoit’shard to survive, becausethereisn’tlots of animals, there are some, butverylittle, and some of them are evenpoisonous. However, in theamazonrainforest, there is a perfectclimate, and itdoesn’tchangebecauseit is verynear to theequator, so youdon’thave to worrythereabouttheclimate. Thebadthing, is thatsometimesthere is a lot of precipitation, so youhave to be wellprotected. Anotherbadthing, is thatthere are verydangerous and poisonousanimals. It is easierthantheother places, becauseyou can killsome to eatwithoutanyproblems, and youalsohavelots of plants.


In conclusion I think that these three extreme environments are called like that because they are difficult for someone to adapt to.

I think that the most extreme ones are the ShahelianAcacia savanna and the North pole. I think this because they have very extreme temperatures; therefore, it is very difficult to survive. Also in the case of those environments is very difficult to be able to find water and food... But in the rainforest, you have the perfect temperature for a human to survive. The bad thing is that it is called extreme because of the animals that live there, they are very dangerous, and some of them very poisonous.
