Answer
|
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
|
2. like the above but it marks a glacier's maximum extent.
|
terminal moraine
|
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
|
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
|
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
|
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
|
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
|
8. a body of water formed between the front of the glacier and the last #1 formed as the glacier retreats
|
glacial lake
|
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
|
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
|
11. the location of a glacier's beginning. has an amphitheatre like apppearance.
|
cirque
|
12. the lake that can form at the bottom of #11 after the glacier is completely melted away.
|
tarn
|
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
|
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
|
15. large, sometimes multiton boulders and rocks left by themselves on the landscape that otherwise would not contain them.
|
glacial erratics
|
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
