Unit 9 Exam Review

All of the following are ways that the atmosphere makes the existence of life on earth possible except -

• shields Earth from small collisons
• maintains a constant temperature
• offers protection from radiation
• allows for gas exchange between plants & animals

Why would life on Earth be unlikely to survive if the liquid iron core did not produce a magnetic field?

• radiation from the Sun would not be repelled which would make the surface too hot
• Sun's heat would not be attracted which woul dmake the suface too cold
• asteroid wouldn't be repelled wich would cause constant explosions on the surface
• oxygen wouldn't be attracted to the lower atmosphere which wouldn't allow for respiraton
