| Question | Answer |
|---|---|
| water from the oceans and the earths surface changes into water vapor | evaporation |
| precipitation that flows over land into streams, rives, and later enters the ocean | runoff |
| rain, snow, sleet, or hail that falls from clouds | precipitation |
| the continuous movement of water from the ocean to the atmosphere, from the atmosphere to the land, and then back to the ocean | the water cycle |
| water vapor cools and changes into water droplets, forming clouds | condensation |
| the downward movement of water through spaces in soil due to gravity | percolation |
| the materials carried down by a stream | load |
| the measure of the change in elevation over a certain distance | gradient |
| the amount of water a stream or river carries in a given amount of time | discharge |
| what does a high gradient level give a stream | more erosive energy |
| a quickly flowing rive with a narrow channel that tumbles over many rocks and has few tributaries | a youthful river |
| a river tat has a wide channel and few falls and rapids and is fed by many tributaries | mature river |
| why does a mature river have more discharge than a youthful river | because of its good drainage |
| a river with low gradient, a wide, flat floodplain, and many bends | an old river |
| a river that is found where the land is raised by tectonic activity | rejuvenated river |
| the process in which material is laid down or dropped | deposition |
| rock and soil deposited by streams | sediment |
| the heavy minerals deposited where the river current slows down | placer deposit |
| a fan-shaped mass of mud deposited in the mouth of a stream | delta |
| a fan-shaped mass of material deposited by a stream when the slope of the land decreases sharply | alluvial fan |
| an area along a river that forms from sediments deposited when the river overflows its banks | floodplain |
| a barrier that slows the process of water down | dam |
| a buildup of sediment deposited along the channel of a river that keeps a river inside its banks | levee |
