Class Information:
Tomorrow, you will be in your seats when the bell rings and quiet, or you will be counted tardy. I am tightening my tardy policy. I will be referring students to the office for tardies as per the student handbook.

You will remain quiet unless you are called on to answer a question, or if you have a question that is ON TOPIC and NOT having to do with something else other than what the class is studying.

The alternative for you, if you choose NOT to remain quiet, is that I will remove you from the classroom and you will serve an after school detention.

Whenever we are somewhere other than my room, follow the instructions given, or else the same alternatives apply. Stay focused on the task you've been given. Otherwise, if you wish to take up MY time having to keep you on task, then I will in turn take up your time after school.

In the computer lab, stay at your station, and be working on your assignment.

Having said that, you now need to be very quiet and do the activites which follow...I should be hearing no one's voices during this period. If you understand what I mean, there IS a difference between talking and whispering.

Learn it or you'll be seeing me after school.

Now...

Click on the links provided and answer the questions below each link. Try doing a right button click on the link and opening the link into a new tab so you have both windows open at the same time.


"Animations "

(Again, if clicking on the link doesn't work, try the right button click and open it into a new tab.)
1) Looking at fig. 12.3, where is snow occurring, and in what direction does the ice sheet move?

2) Looking at fig. 12.6, does the glacier advance during summer?

3) Again referring to figure 12.6, does the ice in the glacier move during the summer?

4) Again referring to figure 12.6, during what season does snow and firn cover the zone of ablation?

5) Again referring to figure 12.6, what happens to the zone of ablation during the summer?

6) Referring to figure 12.8, looking at the cross-section of a glacier, where does Ice move fastest?

7) Referring to figure 12.9, in what two areas do crevasses open up as the ice in the glacier moves forward?

Here is an animation of how terminal and recessional moraines:

"Moraine formation animation"


8) Debris from a glacier is transported to its terminus like a conveyor belt, even when it is receding, which allows for formation of moraines.
How are recessional moraines different from terminal moraines? (As far as you can tell from this animation!)



"Glacier formation interactive! Make your own!"


Click on "Run Now".

Take several minutes to "play" with the controls, changing snowfall, temperature, etc. and what you can view. Drag and use tools to see what you can accomplish with them. After several minutes of observing, perform the changes, then answer the following.

A) Increase snowfall to cause the glacier to advance.
B) Once the glacier has advanced further downslope, click "Set to steady state". Allow it to stay in this form for 5 minutes and observe what happens.

9) Does the ice ever stop flowing forward?

10) Does the glacier continue to advance while in a steady state?

11) What happens to the glacier if you set the snowfall to zero? If snowfall is zero, is the glacier affected by setting temperature lower?

Click the tab for "Advanced".
Change the settings so that the glacier model descends down the valley somewhat, then press "set to steady state".

In the box listed as "graphs Click to turn on "Glacier length vs time", glacial budget vs eleavtion, and air temperature vs elevation. Allow 500 years to pass, then change the air temperature to something colder.

12) What happens to the glacier length?

13) Does the glaceir change thickness? (use the calipers to easure thickness)

14) What happens to the glaciers equilibrium line?

15) Use the meter tool to compare the ablation rate at the terminus (should be different for everyone!) with the ablation rate near the head (beginning) of the glacier.

16) What happens to the glacier if you reduce snowfall slightly?

17) What depositional feature was left behind after you reduced snowfall in #16?


Maneuver through the following website to answer the questions below. The control marked "Glacier type" combined with overview and model should help.

"Glacier formation interactive! Glacier types "


18) What is the key to building glaciers anywhere?

19) North America 18,000 years ago was covered by ice sheets how thick?

20) What might happen to ALL glaciers by the end of the 21st Century?

21) In what types of areas are Alpine glaciers found?

22) What are the two types of Alpine glaciers which may be found?

23) Explain the differecne between an ice cap and an ice sheet.

24) How do tidewater glaciers form?

25) How do striations form?
