|
|
Term
|
Definition
| The flat area behind the levvee's |
|
|
Term
| Why are man-made Levees good/bad |
|
Definition
Good: They allow people to live in areas where a flood would normally make in un-liveable.
Bad: They send more water downstream and get rid of silt in areas upstream |
|

|
|
Term
|
Definition
Large piles of sands
EX: beaches/deserts |
|
|
Term
|
Definition
| The dunes move because the wind blowing the sand over the dunes and cause it to move little by little |
|
|
Term
| How do you stop a dune from moving? |

|
Term
| Why does sea level go down during ice ages? |
|
Definition
| There is evaporation, but there is not run-off into the ocean so it just lowers the sea level during the precipitation phase in the form of snow |
