Question
The Google Earth satellite image above shows Jenny Lake (J), located at the end of Cascade Canyon (A), in Grand Teton National Park, Wyoming. Jenny Lake is dammed on its western edge by a now-forested ridge. Which of the following statements is most likely to accurately describe the ridge
The ridge is a drumlin formed while a decaying glacier flowed out of Cascade Canyon, unable to transport all of its sediment.
The ridge was eroded out of bedrock by the glacier as it advanced across the plain to the west and up Cascade Canyon.
The ridge is a terminal moraine that formed in front of a glacier as it pushed down and beyond Cascade Canyon.
The ridge is an esker which formed beneath a glacier that ran along the edge of the plain, perpendicular to Cascade Canyon.
No glacier is currently present, so the ridge must be attributed to a fault or fold in Earth

Explanation / Answer
1)The ridge is a terminal moraine that formed in front of a glacier as it pushed down and beyond Cascade Canyon.
2)Temperatures rose equally rapidly and high during the Medieval Climate Optimum, before human burning of fossil fuel began to have a significant impact on climate
3)volume of ice stored in icebergs and sea ice
4)brittle solids near their surfaces and ductile liquids at depth
5)A minimum tilt angle causes high latitudes to receive less direct sunlight during the summer, causing an increase in glaciers.
6)erratics
7)~10%
8)All of these are major factors affecting regional climate
9)highly fractured granite
10)unfractured granite
11)All of these factors significantly influence global atmospheric temperatures
12)porous volcanic rock with holes that are isolated from one another
13)~30%
