Term
| What effects do an el nino and la nina have? |
|
Definition
| El nino makes wet areas dry and normally dry areas wet, prevents upwelling and hurts local fishing la nina makes wet areas wetter and dry areas drier |
|
|
Term
| What is polarity and why does water have it? |
|
Definition
| Uneven distribution of charge, because of the way the molecule is formed, with 2 hydrogens to one side |
|
