description | Answer | % Correct |
---|---|---|
2. like the above but it marks a glacier's maximum extent. | terminal moraine | 64%
|
6. large pile of existing glacial till and sand that is shaped by glacial movement. They end up looking like a tear drop or half buried egg, and in areas where these are found there tend to tens to hundreds and they all point in roughly the same direction. | drumlin | 57%
|
1. areas of deposited glacial till(rock and regolith of various sizes) which is left by a glacier in retreat, left behind as the melting drops the rock embeded in said glacier. can be hills or ground level areas | moraine | 57%
|
4. the build up of sediment along an stream internal to a glacier, creating a long relatively narrow and curving embankment. They can be several kilometers long and resemble a raised railroad right of way. | esker | 43%
|
9. a valley that is formed by a mountain glacier as it travels, creating a regular half circle pattern carried for great distances. | trough valley | 36%
|
5. pile of glacial till and sand that accumulates inside the depression of a glacier and is then dropped en masse creating an irregularly shaped hill. | kame | 29%
|
10. a place where a tributary glacier meets a larger heavier glacier, resulting, after retreat, in the smaller glacier's path opening higher up the side the #9. It ends up looking like someone cut away the rest of the path and showing the half circle cross section extremely well. | hanging valley | 21%
|
3. a depression in an outwash plain left by chucks of ice calved off the glacier, surrounded by sediment and then melted. This leaves a depression where the ice used to be. often filled with meltwater or runoff. Since they are often shallow, they can fill with sediment over time and become bogs. | kettle | 21%
|
12. the lake that can form at the bottom of #11 after the glacier is completely melted away. | tarn | 14%
|
11. the location of a glacier's beginning. has an amphitheatre like apppearance. | cirque | 7%
|
13. An instance of #9 where the valley is deep enough that it is filled with ocean or sea water. Tends to be narrow and have deep sides. | fjord | 7%
|
15. large, sometimes multiton boulders and rocks left by themselves on the landscape that otherwise would not contain them. | glacial erratics | 7%
|
8. a body of water formed between the front of the glacier and the last #1 formed as the glacier retreats | glacial lake | 7%
|
16. grooves cut into bedrock by glaciers crawling over it. these have been recorded up to 400 feet long and up to 3 feet deep! | glacial striations | 7%
|
14. the many threaded deposits left in a fan shape by the breided streams flowing out from under the front of a glacier as it melts. | outwash fan | 7%
|
7. In an area that has been depressed by the weight of a glacier, and is slowly gains altitude as the weight disipates. this area is experiencing? | rebound | 0%
