|---|---|
| alpine glacier | aka valley glaciers...build in mountain regions...carve u-shaped valley |
| arid | dry climates...produce thin soils |
| annular drainage pattern | Stream pattern of concentric circles formed on a mountain whose rocks have differing ability to resist weathering |
| continental glacier | glacier that spreads over w wide geographic area |
| dendritic | draining pattern resembling a tree and its branches |
| drainage pattern | arrangement of adjoining streams as seen from above |
| drumlin | oval-shaped mound of unsorted glacial till |
| erratic | large boulder dropped by a glacier |
| escarpment | steep slope or cliff where resistant layers of rock overlie weaker layers |
| esker | winding ridge of sand and gravel deposited by a stream confined to a tunnel under a glacier |
| Finger Lakes | created in Western New York State as the advancing ice deeply scoured former north-south river valleys |
| glacial polish | bedrock surface smoothed by the passage of a glacier |
| kame | delta deposited a stream at the end of a glacier |
| kettle | a depression that may be the result of the melting of a buried block of ice |
| kettle lake | lake formed when a block of glacier ice melts |
| landform | unit of rock of uniform age or composition |
| landscape | general shape of a region on Earth's surface |
| moraine | unsorted mound of sediment deposited directly by moving ice |
| mountain | landform characterized by high elevation and steep slopes (non horizontal rock structure & high topographic relief) |
| outwash plain | layered deposits left by water from a glacier |
| plain | landscape region with horizontal rock structure and low topographic relief |
| plateau | a relatively flat or rolling uplands area deeply cut by stream valleys |
| radial | pattern like spokes of a wheel (radial drainage pattern) |
| relief | change in elevation from one place to another |
| topography | shape of the land surface |
| trellis drainage | pattern in which pst of the streams occupy parallel valleys: develops on folded strata of rocks with differing resistance to erosion |
