Geography snippets from around the world this week.
- We’re looking at cold environments at the moment, this BBC article gives you an idea of how ownership of one cold environment, Antarctica, is more complicated than it first seems. It may be cold, dry and inhospitable, but it turns out everybody wants a chunk of the white continent.
In Mr Monteith’s lesson on Wednesday we briefly reviewed the key factors that influence climate before examining the climate characteristics of three cold environment locations: The European Alps, northern Siberia, and Antarctica.
I mentioned Google Earth which I would strongly recommend all of you install on a computer. Alternatively the school computers should all have Google Earth installed.
A few layers which are worth investigating and saving in Google Earth:
The National Snow and Ice Data Center has a range of different layers showing ice extent in the polar regions and pictures of cold environments around the world.
BRITICE – This is a very exciting project led by a team from Sheffield University. They are attempting to bring together glacial landforms and features created by the ice sheet that covered the British Isles in the last glaciation and present the data in downloadable KML files for use in Google Earth. You can also view the landforms in PDF format. We will be using this site in future lessons.
NOAA ocean currents map – This is the direct link to the KML file that we opened in class that projects global ocean currents in Google earth. It is a useful reminder for the ocean/atmosphere circulation work we looked at in the previous week.
Earth Wind map – Although this is not a Google earth file it is a very interesting website that displays current weather, ocean circulation. By clicking on ‘Earth’ in the bottom left of the page you bring up a control panal. You can change the altitude that is projected by clicking on the numbers next to the height line. Altitude is projected in hPa – Hectopascals, a measure of air pressure, so lower pressure equals a higher altitude.
I want you to come to the lesson next week having accessed at least one of these links or websites.
Mr Monteith’s lesson on Wednesday 25th June focused on global environmental factors that influence the development of cold climates. We focused on:
4. Atmospheric circulation
Now, this is a little test to see who has signed up to receive the emails from the blog and secondly, who is actually reading the blog posts as I would like you to complete some HOMEWORK for next Wednesday and bring it with you.
I would like you to read through the two articles on the links below:
Met Office web link on land and sea ice interaction
Glacier Bay Alaska – Ocean currents influence on glacier development
Reading through the material above I would like you to answer the following questions:
1. How can changes in land and sea ice impact the climate? (Met Office publication)
2.How have ocean currents influenced the development of glaciers in Glacier Bay, Alaska?
A paragraph on each will be sufficient!
First blog post for the geography department – pushing the boundaries of technology in UVHS….
The first lesson on Cold Environments (Mr Mitchell’s lessons) was spent looking briefly at geological timescale and focusing specifically on the Quaternary – Pleistocene and Holocene.
The links to the tasks that were completed in the lesson should be available through this hyperlink which will take you to the UVHS geography Google Drive website. The reading for this lesson came from the legendary geography tome that is Geography – an integrated approach. David Waugh, Pages 90-91 and a number of photocopied sheets which are pre-digital technology. The Powerpoint was adapted from the Geography NING.
If the link does not work for any reason please contact Mr Monteith.
