1. Define gradation.
Gradation refers to the processes that lead to the gradual leveling or smoothing of the Earth's surface over time through natural forces. It encompasses the mechanisms by which landforms are eroded, transported, and deposited, contributing to the overall shaping of the landscape.
2. What are the three key concepts associated with gradation?
Erosion, Transport, Deposition
3. What are some similarities or differences between alpine and continental glaciers?
Differences:
Location; Alpine glaciers are only found on mountain tops where as continental glaciers are only found at the earth's poles regardless of elevation. Size; Alpine glaciers are smaller compared to Continental glaciers.
Similarities:
Both move and cause erosion. Both change the landscape. Both developed in constantly cold temperatures below freezing.
4. Define cirque.
A cirque is a steep sided hollow or amphi-theater type depression that is the result of glacial erosion at the head of an alpine valley.
5. What are two glacial features formed by either erosion or deposition?
erosion - cirque, arete, horn, tarn, v,u shaped vallies
deposition - moraine, erratic (kame, esker but we haven't talked about this yet)
