Learning and Lab objectives
:
This lab activity follows an online lab made available
on the Science Education Resource Center at Carleton College website
(
http://serc.carleton.edu/eslabs/index.html
). The lab has been developed with
support from the National Science Foundation (NSF), the National Aeronautics and
Space Administration (NASA), the National Oceanic and Atmospheric Administration
(NOAA), the National Association of Geoscience Teachers (NAGT), and the
Technical Education Research Center (TERC). Please upload your completed lab
on Canvas.
Go to the following website:
http://serc.carleton.edu/eslabs/cryosphere/lab_overviews.html
On the left side of this website, you find a navigation panel to different parts of the
lab. You will answer questions from Labs 1A, 1C, 2A, 2B, and 4A for this exercise,
but feel free to explore all parts of the “Climate and Cryosphere” section.

Lab 1A: Getting to Know the Cryosphere
Study the image below, which you also find on the website of Lab 1
(
http://serc.carleton.edu/eslabs/cryosphere/lab1.html
), and read through the
introduction to Lab 1 on that website.
Name all the parts of the cryosphere.
Snow, river and lake ice, sea sice, glaciers and
ice caps, frozen ground, ice sheets
Describe the similarities or differences between the time scales at which the
following components of the cryosphere change: snow, glaciers, ice sheets.
Snow, glaciers, and ice sheets are all part of the cryosphere, which refers to the
frozen parts of the Earth's surface. They all change over time, but at different rates.
Snow can change within hours or days, while glaciers can take years or decades to
change significantly, and ice sheets can take centuries or even millennia to change.

Cut out and tape together the cryosphere map that is found at the end of this lab
document (you can also look for an image of what the completed “globe” should look
like on the Lab 1A website, http://serc.carleton.edu/eslabs/cryosphere/1a.html). This
globe shows the distributions of snow, ice, etc. averaged over several decades.
Answer the following questions (some of which you also find on that same website):
What parts of the cryosphere are only found near the poles?
Ice Caps
On December 26, 2000, there were reports of ten to twenty inches of snow across
the Texas panhandle, including nearly twenty inches in the city of Amarillo. Why
doesn't the map show snow in Texas?
The map wasn’t updated
Where in North America do you find glaciers and ice caps?
Alaska, western Canada,
Rocky Mountains, and some parts of Greenland
To which latitude does sea ice extend in the northern hemisphere?
35 degrees north
latitude
To which latitude does sea ice extend in the southern hemisphere?
65 degrees
south latitude
Where do you find glaciers close to the equator? Why do you find them there?
Glaciers can be found near the equator in high-altitude areas, such as the Andes
Mountains in South America and Mount Kilimanjaro in Africa because at high
