Heat spike in 2010 lead to rebound of Greenland land mass
Scientists have used GPS data to demonstrate that a global spike in temperature in 2010 has lead to exceesive melting of the Greenland Ice Sheet. This in turn has lead to isostatic uplift of the crust in response to the changed equilibrium as the ice was removed through melting.

Toads predict earthquakes?!
Although it has been known for sometime that animals become agitated immediately prior to an earthquake, it would appear that toads become aware of the impending danger sometime before an earthquake strikes!

Canada to renege on its pledges over climate change
Critics have been asking if it is fair that Canada is allowed to withdraw from its promises over reducing emissions.

Canada withdraws from pledges over climate change
The UK has also come under attack for its support to Canada over the Tar Sands.
The tar sands of Northern Alberta, Canada – also called oil sands – are one of the largest remaining deposits of oil in the world. Developing the tar sands has created the biggest industrial development project, the biggest capital investment project, and the biggest energy project in the world. It has also created a literal hell on earth.

In a time when Oil reserves are getting limited and expensive to extract is the impact of extracting bitumen from the Tar Sands of Canada and Venezuela worth the environmental cost. Or does there need to be stricter controls over the exploitation of this resource?
How is the land being regenerated after extraction?

Year 10 Rock Cycle Homework
This week I'd like you to follow a rock through the rock cycle.
Start with Granite as an Intrusive Igneous rock and then follow it through the rock cycle. Create a flow chart to show what happens at each stage. Consider the component minerals of granite (Orthoclase, Plagioclase, Quartz and Mica), you could follow just one of these through the rock cycle (Quartz might be the easiest?).
How does Granite break down? What Sedimentary rocks forms from the mineral/minerals? What happens to this rock when heat and pressure are applied?
Geology through the Rock Cycle
