Term
| Why is weather hard to predict? |
|

|
Definition
|
|
Term
When a cold front meets a warm front is will probably
rain. Why is this? |
|
Definition
| when a cold front meets a warm front it will rain because warm air is forced upward by cooler air. Warm air is forced upward by cooler air and exerts low pressure. |
|
|

|
Definition
|
|
Term
| --- air holds more moisture or water vapor than --- air. |
|
Definition
| Warm air holds more moisture or water vapor than cold air |
|
|
Term
| What affects the humidity of air? |
|
Definition
| The humidity of air is affected by the area and temperature over which an air mass formed. |
|
|
Term
| What affects the rate of evaporation? |
|
Definition
| The greater the humidity level, the slower the rate of evaporation because there is already a lot of water vapor in the air. |
|
