<u>Note</u>: I have provided my own definition for the ninth term (firn) in the third image for which the definition was missing
<u>Answer</u>:
A. 1. The height of anything above a given planetary reference place, especially above sea level on Earth, the extend of distance upward - <u><em>altitude
</em></u>
2. The movement of glacial ice and snow as a result of gravity - <em><u>basal slip</u></em>
3. When chunks of ice break off at the terminus, or end of a glacier - <em><u>calving</u></em>
4. An amphitheater like valley formed by glacial erosion - <em><u>cirque</u></em>
5. A long period of cold climate where glaciers cover large parts of the earth - <em><u>ice age
</u></em>
6. Miniature ice sheet - <u><em>ice cap</em></u>
7. The angular distance of a place north or south of the Earth’s equator usually expressed in degrees and minutes - <em><u>latitude</u></em>
8. The study of the Earth’s atmosphere in prehistoric times - <em><u>paleoclimatology</u></em>
9. Below the surface in the region under enough pressure that the ice is no longer brittle the ice distorts and changes shape due to the pressure of the above layers - <em><u>plastic flow</u></em>
10. When a glacier loses more snow and ice due to melting and calving than it accumulates - <em><u>glacial retreat</u></em>
B. 1. A deep crack or area of cracks that result from the upper layer of the glacier ice breaking when the lower layer of ice flows - <em><u>crevasses, aka zone of fracture
</u></em>
2. Snow accumulation converted into granular ice over time - <em><u>zone of accumulation
</u></em>
3. A boulder left behind by a glacier - <em><u>glacial erratic</u></em>
4. Scratches or gouges cut into bedrock by glacial abrasion or rubbing - <em><u>glacial grooves or striations</u></em>
5. Unsorted sediment deposited directly when glacial ice melts - <em><u>moraine
</u></em>
6. A pile of rocks left behind by a glacier - <em><u>glacial till
</u></em>
7. The location on a mountain glacier when the rate of accumulation is equivalent to the rate of melting - <em><u>snowline or equilibrium line
</u></em>
8. the terminus or down-slope end of the glacier where ice and snow are melting faster than accumulating - <em><u>zone of ablation (or wastage)
</u></em>
9. <em><u>Firn</u></em> = crystalline or granular snow that has not yet been compressed into ice. If is found especially on the upper part of a glacier
