I IntroductionI Introduction
This presentation will show you a sampling of the thousands of images
taken of Earth from manned spacecraft. You will see images of plate boundaries,
atmosphere-ocean interactions, rivers and mountains, as well as the results of anthropogenic
influences on Earth’s systems. We hope you will complete this program with a new-found
interest in how the Earth works.
The site listed below contains all hand-held photography taken from orbit. Enjoy.

XVIII Exercises
XVIII ExercisesWater Cycle:
• Where do we find freshwater? (rivers; lakes; groundwater; glaciers)
• Where do we find saltwater? (oceans; lakes with closed basins, i.e., the Great Salt Lake)
• What are common sources of freshwater for drinking water and agriculture? (rivers; lakes; groundwater)
• What is the source of drinking water for Austin? (Colorado River water)
• What is the source of drinking water for San Antonio? (Edwards Aquifer)
• Discuss some advantages and disadvantages to the use of surface water versus groundwater as a drinking
water resource.
(River water availability will depend on recent precipitation history and thus may be undependable. This is
one reason for the dams on the Colorado River. River water is more likely to carry diseases and thus must
be carefully processed by a water treatment plant. Groundwater in some places is a finite resource, where
water is extracted, but it is not replenished [i.e., the Ogalalla Aquifer]. Thus the groundwater is mined, and
once pumped it is gone. Once polluted, and aquifer is extremely difficult to clean-up.)
Rock Cycle:
• Discuss one aspect of the rock cycle described in this presentation, weathering transportation and
deposition of sediment. (see http://www.science.ubc.ca/~geol202/rock_cycle/rockcycle.html)
• Where does weathering occur? (soils, bare rock, beneath glaciers)
• How is water involved with chemical weathering? (Some minerals partially dissolve in liquid water forming
dissolved ions and new minerals, clay minerals for example; this reaction is more rapid at warmer
temperatures.)
• How are glaciers involved with physical weathering? (Flowing ice incorporates rock pieces and scrapes
these pieces of rock against the bedrock and physically disaggregates a rock, forming fine particles.)
• What are the products of weathering? (dissolved chemicals, new minerals, and smaller pieces of pre-
existing minerals [sand for example]).
• Where do these products of weathering end up? (in lakes, oceans, beaches, etc., transported by the action
of wind and water)
For any given image in this presentation, determine what part(s) of the rock cycle or water cycle we are viewing.

Professor William R. Muehlberger
William R. Muehlberger is a structural geologist who received his
Bachelor's, Master's, and Ph.D. degrees from the California Institute of
Technology. He has conducted field investigations all over the world, and
recently published the definitive Tectonic Map of North America, for which
he received the Best Paper Award from the Geological Society of America.
During his tenure as professor and chairman of UT's Department of
Geological Sciences, Muehlberger supervised more than 80 Master's and
Ph.D. students. Muehlberger has also served as principal investigator of the
Field Geology Team for the Apollo 16 and 17 Moon landings. His team was
involved in landing site selection and analysis, traverse design, astronaut
training, real-time mission support, and in post-mission data analysis and
debriefing. He continued this work with NASA on the Skylab and Apollo-
Soyuz Missions, and presently teaches geology to Space Shuttle astronauts.
For his work over the years, Muehlberger has received the Medal for
Exceptional Scientific Achievement and the Public Service Medal from
NASA, as well as the Houston Oil and Minerals Corporation Faculty
Excellence Award.
