|
|
Term
|
Definition
| cold air is heavier and denser and moves along the surface, pushing the warmer moist air up into the atmosphere. Warm air increases in elevation and the vapor water will condense as it reaches colder levels and form rain (mostly in the middle of the USA) |
|
|
Term
| How does lightening form? |
|
Definition
| lighter positive charged rain droplets and ice particles rise to the top of a heavier negative charged particles sink to the cloud's base |
|
|
Term
|
Definition
| when water droplets in raising air condense and freeze. Ice crystals bounce up and down in the strong updrafts and grow. When heavy enough to overcome draft they fall. |
|
|
Term
|
Definition
| large, lowering, and rotating base of a cumulonimbus cloud that potentially forms tornadoes. It indicates the area of primary and strongest updraft. |
|
|
Term
|
Definition
| applied to a cellular pattern of pouches hanging underneath the base of a cloud. |

Term
|
Definition
| has a channel that consists of a network of small channels seperated by small and often temporary islands forming broad, flat floodplains |
|
|
Term
|
Definition
| formed when the moving water in a stream erodes the outer banks and widens its valley. Broad, multi-channe, with sediment, dry climate, high erision. |

Definition
| forms when a river empties into a larger body of water |
|
|
Term
|
Definition
| on land where a river emerges from a mountainous area and flows out onto a more gently sloping plain. |
|
|
Term
|
Definition
| level at which water spills over banks, every 1-3 years, increased by: verlocity, depth and stream width. |

|
|
Term
|
Definition
| fast moving, liquified landslide of unconsolidated, saturated debris (looks like concrete) Its texture and viscosity is what makes it differnent from a mudslide |
|
|
Term
|
Definition
| rock or other material used to amror shorelines, streambeds, bridge abutments, pittings and other shoreline structures against scour, water or ice erosion. Often made of limestone or granite. |

Definition
| higher elevation as it moves over rising terrain. As the air mass gains altitude it quickly cools down adiabatically, which can raise the relative humidity to 100% and create clouds and, under the right conditions, precipitation. |
