Due to several days of downpours the rivers have overflowed their banks causing localized flooding.

• This is a long term impact.
• This is a short term impact.

Long term environmental changes...

• Allow adaptation to occur
• Do not allow for adaptation to occur
• Occur suddenly and are very cataclysmic
• Kill everything suddenly (mass extinction)

An organism that cannot adapt to changes in the environment will most likely - 

• produce more offspring
• die
• change its traits to survive
• store more food

Short term environmental changes...

• Allow for adaptation to occur
• Always kill everything within 10 seconds
• Only affect animals and not plants
• Do not allow for adaptation.  Organisms must leave (migrate) or die

Most water pollution is the result of

• human activities.
• drought.
• volcanic eruptions.
• storms.
