They are adapted for that. Are U asking the effect of these environ. on the biological systems and the changes required to avoid bad effects ?

Are you looking for examples of how they survive or something else?

bacteria found near volcanic vents. Can withstand deep sea pressure and intense heat from the magma/lava.

Thank you mithrilhack - What level biology class are you in?

I'm in a first year bio class but I have read some books on evolution back in my religion busting days :-D.

I'm in the middle of my religion busting days myself - I'm in high school and I'm in my first biology class.

archea can survive in extreme condition because of a lot of things; to name some, halophiles have compatible solute to avoid problem with osmosis, hyperthermophils have heat stable enyzmes (more ionic groups) and membrane with more sturated lipid .... stuff like that, they are fit to survive in those kind of condition

If archaea had a brain, they would probably think: How can human survive in the presence of O2? Each organism is adapted to it's environment, including archaea
