In order to for astronauts to be self-sufficient (requiring no outside supplies from earth) on a space station or other planets, what do they need? List and explain the necessary thing needed to create a closed ecosystem. Describe the role each thing you have listed will play.

Explanation:

1. Oxygen, without oxygen no human can live, In space, there Is zero oxygen

2. Water, Astronauts will definitely need some sort of water since nearly every living thing requires It

Normal fault - a dip-slip fault in which the block above the fault has moved downward relative to the block below. This type of faulting occurs in response to extension and is often observed in the Western United States Basin and Range Province and along oceanic ridge systems.

thrust fault - a dip-slip fault in which the upper block, above the fault plane, moves up and over the lower block. This type of faulting is common in areas of compression, such as regions where one plate is being subducted under another as in Japan. When the dip angle is shallow, a reverse fault is often described as a thrust fault.

strike-slip fault - a fault on which the two blocks slide past one another. The San Andreas Fault is an example of a right lateral fault.

Strike-slip Fault Animation

A left-lateral strike-slip fault is one on which the displacement of the far block is to the left when viewed from either side.

A right-lateral strike-slip fault is one on which the displacement of the far block is to the right when viewed from either side.
