Academic Honesty (Acknowledgement Required)
The Virtual Field Trip to Central Texas is to be completed by yourself; you should not work with a partner
or group. Do not search for answers on the internet because 1) it is cheating; 2) answers that are posted
are incorrect, and we’ll know where you got them from, and; 3) the questions change every semester. Be
careful if you watch the videos with closed captioning because the spelling of geologic terms is often
incorrect or misinterpreted by the captioning software, so you may end up with a wrong answer. If you
are unfamiliar with a word or geologic concept, it is okay to look it up online to find the correct spelling
and definition. If you find yourself needing help, physical geology teaching assistants staff the
Geoscience Learning Center
.

attest that I have not
violated the UH Academic Honesty code. I completed this assignment
by myself and did not copy any portion of my answers from another
student, a website, or any other source.
Instructions
The virtual field trip to Central TX is a Google Earth tour that will require you to watch videos of our
field trip stops, answer questions, and make interpretations on GigaPan images (very large, high quality).
In addition to this document, you will need the accompanying PowerPoint file for image
interpretations.
Head back to the field trip page if you still need the PowerPoint file. All written answer
should be in this document.
Accessing the Trip
This virtual field trip has been built in Google Earth.
Click here to access the trip
. The first thing you will
see is an overview of Texas, and the field trip stops. In the menu on the left side, click on “Present” to
begin the tour. At each location a box will appear on the right side of the screen with information about
each stop, the videos you need to watch, and links to the GigaPan images. Use the menu on the bottom
left to move between stops.
Written Answers
All answers need to be written in complete sentences to receive credit
and typed in the supplied boxes.
Your responses will appear in a green-colored font, do not change this. Any answers not written in
complete sentences will be marked as incorrect and will not receive credit.
Taking Snapshots/Screen Captures
You’ll need to take snapshots of high-resolution images from the field trip stops. Follow the directions
below according to your operating system. Paste the images into the PowerPoint answer file on their
appropriate slide. Image questions will ask you to make annotations on your snapshots to highlight items
of geologic interest. Common annotations include drawing circles and lines. Use Microsoft PowerPoint
for making these annotations.
PC Directions
