4.2 Revealing past plate tectonic events

In Section 3 we referred to the Caledonian and Variscan Orogenic Belts. These are interpreted as representing past destructive plate margins or more strictly speaking, representing the final phases of ocean closure that resulted in continental collision. Section 4 explores the extent to which it is possible to detect different

4.4 Robert Owen and New Lanark

Robert Owen (1771–1858) was one of the most important and controversial figures of his generation. He lived through the ages of Enlightenment and Romanticism and was personally touched by the ideas and dramatic changes that characterised that era. Profitting enormously during the first half of his life from the progress of industry and having the financial means, he later devoted himself to publicising and practising his social and economic ideas. Most of these derived from Enlightenment no

2.1 A lack of insight?

One of the curious things about learning to write essays is that you are seldom offered much insight into what you might be setting out to produce. You know only too well what your essays look like and what your tutor says about them, but you don't know what else you might have done. For instance, you have very little idea what other people's essays are like and what comments they get back. Perhaps you are told your essay ought to be ‘more structured’ or ‘less subjective

5.2 Doing and undoing

Now try the following.

Think of a number. Add 4. If my answer is 11, can you work out what number I was thinking of?

You might have said ‘What number do I have to add on to 4 to get 11?’ or perhaps ‘If I take away 4 from 11 what number do I get?’ In both cases you should have arrived at the answer 7.

In the second method ‘subtracting 4’ undoes the ‘adding 4’ in the original instructions.

This process can be illustrated by a ‘doing–undoing diagram’

3.1 Diurnal living

In three particular respects, anthropoids have evolved features that have given them a competitive edge over other animals, especially prosimian primates. They have a diurnal instead of a nocturnal pattern of activity, they form all year round male-female relationships and live in social groups (which evolved differently and independently in lemurs), and they communicate extensively through gestures and vocalisation.

A diurnal pattern of activity means that, like us, nearly all anthropo

Because these online diaries offer instant publishing opportunities, you potentially have access to a wealth of knowledge from commentators and experts (if they blog) in a
