4. Examples of Environmental Systems

Try these first

1. 1.

   What is molecular diffusion?

   Hint

   Think about how smells spread in the air.

2. 2.

   What term is often used interchangeably with bulk flow?

   Hint

   It's a word often used to describe fluid movement.

3. 3.

   What is the primary transport mechanism in fast-flowing rivers?

   • Molecular diffusion
   • Advection
   • Both A and B

   Hint

   Think about how quickly pollutants move in a river.

4. 4.

   True or False: In a stratified lake, diffusion can occur more prominently in some layers than others.

   • True
   • False

   Hint

   Think of how temperature affects lake layers.

5. 5.

   Design an experiment to measure diffusion rates in two different environmental media like water and air.

   Hint

   Consider how temperature or stirring may alter your results.

6. 6.

   Analyze how groundwater flow in a clay-rich area could affect the spread of contaminants over time.

   Hint

   Think about the implications of slow vs rapid flow.
