Save a picture of each feature from Google Earth in Profile view (i.e., like you’re standing on the ground looking at it, as opposed to from the air), and give me with a Latitude and Longitude of where you got it (which you can read right off the screen). Compare the latitudes and longitudes of all the features you found and all the locations you explored.
1 NAME _____ _____ Glaciers and glacial landscapes Introduction: In this lab we will be using Google Earth to explore and identify geologic features associated with glaciers. As with previous labs you will capture images to insert below as part of your answers. Typed answers should be in a different colored text. Figure 1: This is a labeled image from Alaska showing a variety of the …

Mar 15, 2020 · Commonly originating from mountain glaciers or icefields, these glaciers spill down valleys, looking much like giant tongues. Valley glaciers may be very long, often flowing down beyond the snow line, sometimes reaching sea level. Tidewater glaciers. As the name implies, these are valley glaciers that flow far enough to reach out into the sea.
The largest mountain glaciers are found in Arctic Canada, Alaska, the Andes in South America, and the Himalaya in Asia.
Rock glaciers are combinations of ice and rock. Although these glaciers have similar shapes and movements as regular glaciers, their ice may be confined to the glacier core, or may simply fill spaces between rocks. Rock glaciers may form when frozen ground creeps downslope.
Malaspina Glacier in Alaska is one of the most famous examples of this type of glacier, and is the largest piedmont glacier in the world. Spilling out of the Seward Icefield, Malaspina Glacier covers about 3,900 square kilometers (1,500 square miles) as it spreads across the coastal plain.
Tidewater glaciers. As the name implies, these are valley glaciers that flow far enough to reach out into the sea. In some locations, tidewater glaciers provide breeding habitats for seals. Tidewater glaciers are responsible for calving numerous small icebergs, which although not as imposing as Antarctic icebergs, ...
Another example is the Greenland Ice Sheet. In the past ice ages, huge ice sheets also covered most of Canada (the Laurentide Ice Sheet) and Scandinavia (the Scandinavian Ice Sheet), but these have now disappeared, leaving only a few ice caps and mountain glaciers behind.
Ice shelves occur when ice sheets extend over the sea and float on the water. They range from a few hundred meters to over 1 kilometer (0.62 mile) in thickness. Ice shelves surround most of the Antarctic continent.

This activity part of an introductory-level required environmental geology course. The tours of glaciers uploaded here also provide a great means to illustrate glacier changes due to climate change. However, this is best learned by the students exploring a glacier for themselves.
To have the students make their own observations and identify the consequences of climate change on an alpine glacier, not to just read about it.
The glacier tours can be used as a standalone presentation for students who are not ready to dive into Google Earth.
If students look at the two glacier tours on their own, they would need a worksheet or other guidance to keep them on track.
The Google Earth tours are loaded with quality information and present data is in several different formats. These glaciers may have undergone additional changes since this activity was created, so it may be worth investigating additional sources of imagery or data.
