Maps of glaciers

I thought it would be useful to have a pictorial illustration of where glaciers are found in the world. (The images are from http://ga.water.usgs.gov/edu/earthglacier.html)

The map below shows where glaciers are found in the world today. The white areas show where glaciers are and the white spots in the ocean show where glaciers are found at sea. Most notably, Antarctica has the most glaciers.

After my previous blog where I stated it might be important/useful to look at the past ice ages, I also found a map which shows how glaciers have changed since then. Visually seeing this and hearing a teacher say this/read the information themselves would help reinforce the knowledge with the students and hopefully help it to be committed to memory. 

The map shows that during the last ice age, much of the northern hemisphere was covered in glaciers. however the map also shows that much of the world has glaciers and ice including Asia and the USA. It might also be useful to mention when showing the two maps that climate changes today still affect glaciers.  

-->These two maps could be used as in an activity e.g. 'spot the difference' style. This would allow students to familiarise themselves with different parts of the world and state how they have changed. It might also be useful to ask 'why?' and see if they can think why we have less glaciers today (linking to things such as climate change, increase in GHG's etc). This 'why' question can be developed and extended further with older years and push them to think more and more as to why things have changed, rather than just accepting 'It's got hotter'. Push them to say why is it hotter, who has done this, when did this occur, how did it occur etc.
