Transcript of Extreme Environments

Extreme Environments
Extreme environments are places where human survival is difficult or impossible.
Volcanoes are one of the extreme environment.
What is the volcano
A volcano is an opening, or rupture, in the surface or crust of the Earth or a planetary mass object, which allows hot lava, volcano ash and gases to escape from the magma chamber below the surface.
Ocean is another extreme environment.
Most of Earth's surface is covered by oceans. There is no air to breathe, and crushing pressure increases the deeper you go.
Polar Regions is an extreme environment too.
Polar Regions
There are two polar regions: the Arctic and the Antarctica. Arctic is a cold area around North pole and Antarctica is a cold area around South Pole. The average annual temperature is 0 degrees Celsius. It is usually identified as the area north of the Arctic Circle.
Desert and space are the extreme environment.
Deserts are very dry areas that get less than 25 cm of rain a year. Most people think that deserts are hot place, but deserts can also be very cold. Both the Arctic and Antarctica are deserts. Animals and plants that live in deserts have special adaptions that allow them to survive, despite lack of water.
Space is the region beyond Earth's atmosphere ---the ultimate extreme environment. The temperatures are really extreme---from boiling hot in the light of the Sun to freezing cold in the shadow of Earth---and there is no air to breathe.
