Homework set Monday 1 October Unit 1

1.  ESSAY

Describe and explain the global distribution of volcanoes (10 marks)

HINTS

•Make sure you have a clear structure – write an introduction, then describe where they occur, followed by a section explaining why volcanoes occur there
•In the introduction, define ‘Volcano’, e.g. ‘A volcano is a point where magma has risen from below the Earth’s surface and been ejected above ground’.
•Next describe the global distribution of volcanoes, e.g. ‘Volcanoes can be found all along the mid-Atlantic Ridge. They are also found around the edges of the Pacific Ocean (Ring of fire), particularly around Japan and Indonesia, and along the west coast of America. They are also found in the centre of the Pacific Ocean in Hawaii’.
•Now explain why volcanoes happen at each of the locations you have  described. Make sure you use appropriate language, e.g. ‘The mid-Atlantic Ridge is a constructive boundary. Here the mantle is under pressure from the overlying plates, and when they move apart pressure is released and the mantle melts, forming magma. This is less dense than the plates so it rises and can erupt to form a volcano.
INCLUDE EXTENSIVE DETAIL AND DIAGRAMS AS THIS IS YOUR NOTES ON THE PLATE BOUNDARIES!
Use these to add info
2.  Read this Geofile about earthquakes to provide you with extra knowledge beyond your earthquake comparisons.
To be completed by Friday 5th October.

Globalisation of work…great for Unit 1 Going Global

In the near future, at least five billion people around the world will use some form of mobile device to download information, access knowledge and coach and teach each other.

Some will have the intellectual capacity and motivation to really make something of this opportunity, wherever they happen to be born.

These people will want to join the global talent pool and, if possible, migrate to creative and vibrant cities.

By doing so, this vast crowd of talented people will increasingly compete with each other, continuously upping the stakes for what it takes to succeed.

It seems that this will impact all of us in three ways – the hollowing out of work, the globalisation of virtual work, and the rise of the ‘transnational’.

Mobile phone technology to help Chile with Earthquakes

In times of threat from natural hazards everyone tries to connect using landlines and mobile phones, networks become severely overloaded.

This has an effect on official warnings. For the government, it is also tricky to get through to the population.

To deal with the problem, the Chilean authorities imported new emergency alert technology in 2011.

The software, developed by Israeli company eVigilo, uses a geo-targeted system that allows the officials to send out mass alerts simultaneously to computers, pagers and mobile phones, as well as radio and television.

Messages are meant to reach millions within seconds – even if all networks are busy.
