Weathering Water
| Question | Answer |
|---|---|
| weathering | |
| erosion | |
| depotision | |
| 4 factors that influence W,E,D | water, ice, gravity, wind. |
| cut bank | where erosion increases on the outside of a meander because water speeds up |
| pointbar | where deposition increases on the inside of a meander because water slows down |
| delta | a point at the end of a river or stream, where the water slows down, and sediment builds up creating a little island. |
| alluviall fans | |
| granient | how steep or flat an area is |
| load | the amount of sediment carried in a stream or river. |
| discharge rate | the amount of water being moved at once |
| oxbow lake | a crescent shaped lake created by a meander being cut off by erosion and depositon. |
| shoreline | the edge of a shore where water and the land meet |
| sea cave | a cave created by weathering of waves crashing against the shore |
| sea arch | an arch created by water splashing against the land and weathering it |
| sea stack | a stack of deposited sediment stacked to create a long tall stack of rock. |
| plucking | pieces of rock lifted out by ice |
| grooves | bedrock gouged deeply by rock fragments embedded in glacier |
| striations | shallow marks in bedrock |
| continental glaceirs | spread across entire continents |
| alpine glacers | form in mountainous regions |
| till | material left behind by glacier |
| moraine | till deposited in a ridge at the glacier edge |
| outwash | material from meltwater |
| eskers | winding ridge from outwash |
| erratic | a piece of rock that differs from the size and type of rock native to the area in which it rests. |
| kettles | shallow, sediment filled body of water |
| Topography | the study of elevation and factors of land |
| Topographic map | a map that shows the facrots and landmarks of a peice of land |
| contour lines | lines that connect points that are of the same elevation. Gentle- Lines are far apart Steep- Lines are close together |
| Index contour lines | lcontour lines that are labeled to help you find the contour interval. In bold |
| V's at the stream | Contour lines form V’s that point upstream when they cross a stream. |
| contour intervals | the difference in elevation between two contour lines that are side by side. |
| map scale | compares distances on the map with distances on earth. |
| legend | explains symbols used on the map. |
| benchmark | a point where exact elevation is known and is marked with a brass or aluminum plate. It is marked BM on the map with the elevation numbers given in feet. |
| hachure lines | regular contour lines with small segments sticking out from it. |
| elevation | how high and low the ground is in relation to sea level. |
| Relief | describes the low valleys and the high mountain tops. |
| Profile | different views of elevation to show different things |
| geosphere | the rock portion of earth made up of four different layers |
| asthenosphere | soft, slowly loving layer beneath Earth's surface |
| lithosphere | Earth's rigid outer layer made up of the crust and solid upper mantle that is broken into pieces that move on the top of the asthenosphere |
| mantle | layer beneath earths crust that is mostly less solid that the crust |
| outer core | liquid, metal layer surrouning Earth's inner core |
| inner core | the solid metal center of earth with high pressure and tempertures |
| crust | the thin, hard outer layer of earth |
