Europe- Russia- Mt. Elbus

Elbrus Mount Elbrus, Russian Gora Elbrus, boasts the highest peak of the Caucasus mountains, southwestern Russia. It is an extinct volcano with twin cones reaching 18,510 feet (5,642 meters) and 18,356 feet (5,595 meters). The volcano was formed more than 2.5 million years ago. Sulfurous gases are still emitted on its eastern slopes, and there are many mineral springs along its descending streams. A total area of 53 square miles (138 square km) of Elbrus is covered by 22 glaciers, which feed the Kuban River and some of the headwaters of the Terek. Elbrus is a major center for mountaineering and tourism in the Caucasus region.

Directions

  1. Take out a sheet of notebook paper. Write your name, date, and grade on the first three lines.

  2. On your paper draw a mountain with twin cones.

  3. Now, label the parts of a cone volcano.

How are glaciers formed? What happens as they melt and move? What do they mean to the world, even if people don't live near them?

Go to the following link to complete the Glacier lab . Make a mini glacier and explore. Record your results on a separate sheet of paper. https://serc.carleton.edu/eslabs/cryosphere/3c.html

Glaciers Simulation

Directions

  1. Take out a sheet of notebook paper. Write your name, date, and grade on the first three lines.

  2. Click on the PhET Glaciers simulation link (http://phet.colorado.edu/en/simulation/glaciers) and play with the sim for five minutes. What did you find? Discuss your ideas with your partner, a friend or family member.

  3. Observe what happens to the glacier as you adjust different parameters in the simulation.

  4. Draw a table on the back of the paper that looks like the one below.  Record your observations in the table.

    Action

  5. Skip a line after the table and write #1. Next to #1, answer the following question.
    Where is the glacier flowing the fastest and the slowest?  Suggest a reason for this difference.

  6. Skip a line and write #2. Then answer the following question.
    What claims can you make about the relationship between the amount of snowfall and the movement and thickness of glaciers? Provide evidence for your claims.

  7. Skip a line and write #3. Then answer the following question.
    What claims can you make about the relationship between the average temperature and the movement and thickness of glaciers? Provide evidence for your claims.

  8. Skip a line and write #4. Then answer the following questions.
    • Look at the rocky debris that the glacier is picking up and transporting. Where is the debris being deposited?
    • What happens if the glacier stops for a while then retreats?  
    • What is left behind? What is this pile called?
Don’t forget to place this completed activity/product into the pocket of your white Journey into Reading envelope.
