An extreme environment is an environment where an organism that can't or can with difficulty survive. The five known extreme environments are: polar regions, deserts, oceans, volcanoes and outer space.
Polar Regions
-in order to survive in polar regions, humans use insulation, a material that traps heat from going out into the environment in order to survive as well as snow houses or igloos, snow sleds, snow shoes, parkas, and oil lamps. These were all invented by the Inuit or formerly known as Eskimo people.
- it is a challenge to survive in polar regions because of the extreme temperatures.
Deserts
-deserts aren't necessarily hot; a desert is a place with extreme temperatures.
-it is a challenge to survive in deserts because of the extreme temperatures.
Oceans
-humans have developed technology that can be used underwater to explore oceans, such as RADAR, Radio Detection and Ranging, SONAR, SOund Navigation And Ranging, and SCUBA, an acronym for Self Contained Underwater Breathing Apparatus.
-it is a challenge to survive underwater because of the lack of air and because of the water pressure increasing the farther down you go.
buoyancy - the ability to float.
water pressure - the application on force by water that increases by depth.
Volcanoes
-volcanoes are a danger to humans because of their being unpredictable, and their extreme temperatures.
Outer Space
-it is a challenge to explore and survive in Outer Space because of extreme temperatures, and lack of air.
People explore extreme environments in the hopes of finding new places to live, understanding human's past, discovering new species, finding new resources, and to understand and protect our world.
Canada has contributed to space exploration by inventing the Newt Suit, which enable divers to move more agilely under water, and the Deep Worker, a submersible vehicle that can take pictures and samples of the ocean.
