Google Earth

Sharing on Google Earth again though you can still refer to my earlier posts on how you can use it for Geography - http://geogshare.blogspot.sg/search/label/Google%20Earth
Google Earth is very useful to show authentic learning to students as well as to illustrate the concepts of place and space to the students.

I hope that it is sustained as I did one activity with the students on weather - the influence of latitude, altitude and distance from the sea on temperature in 2016. I was pretty upset when they remove the temperature layer from Google Earth - wasted my effort in designing the worksheet but at least that batch of students benefitted (Sec 3 Pure Geog 2016)

Sharing on how I use Google Earth for my lesson on Volcano:
I have place mark   two volcanoes  to show the relief of stratovolcano and shield volcano  with reference to the 2015 Geography Elective Paper on  the comparison of Mt Mayon and Prestahnukur.With Google Earth I will also be able to show the plates which cause their formation.

I have also placemark a few volcanoes to illustrate the benefits and risks of living near volcanoes
Nevado del Ruiz  eruption in 1985 (as mentioned in the notes and textbook -• The eruption of Nevado del Ruiz in the Andes mountains of South America in 1985 released a pyroclastic flow. The mixing of pyroclasts and glacial ice along its path triggered lahars which engulfed the town of Armero and killed more than 20,000 people)


the eruption of Eyjafjallajokull in Iceland in 2010 produced extensive volcanic ash clouds that posed danger to aircraft engines an structures.The eruption resulted in a closure of air space over much of Europe, causing delays to 1.2 million passengers daily and costing the airline industry a total of US$1.8 billion.

Mt Merapi  - where many are involved in agriculture due to the rich volcanic soil so despite the risks many still return https://www.voanews.com/a/economic-life-slowly-returns-to-indonesias-mount-merapi--137062538/168354.html

Kimberley in South Africa are one of the world’s richest sources of diamond.

I would also highlight  the location of the volcanoes e.g. ring of fire (oceanic-continental convergent), Mariana Islands (oceanic-oceanic convergent), Mid-Atlantic (oceanic-oceanic divergent), along the Great East African Rift Valley (Continental-continental divergent)

You can download the volcano kmz file here:

Of course you can also refer to the worksheet and kmz file which I have used for the students to explore the different types of plate boundaries as well as the features and landforms found at the respective plate boundaries:
