Conclusion Earthquakes shake the ground surface, can cause buildings to collapse, disrupt transport and services, and can cause fires. They can trigger landslides and tsunami. Earthquakes occur mainly as a result of plate tectonics, which involves blocks of the Earth moving about the Earth's surface. The blocks of rock move past each other along a fault. Smaller earthquakes, called foreshocks, may precede the main earthquake, and aftershocks may occur after the main earthquake. Earthquakes are mai
1.2 Earthquake-triggered landslides and tsunami As well as being highly destructive in their own right, earthquakes can also trigger two other very destructive natural hazards. One of these is a landslide. This is a rapid movement of earth materials down a slope, the materials ranging from huge boulders to soil. Landslides can involve the movement of just a small amount of material or enough to bury whole towns in their path. They can have a number of causes, of which earthquakes are just one. The shock of an earthquake may be sufficient t
1.1 What happens during an earthquake? The Earth is an active planet, with activity occurring in the oceans, in the atmosphere and in the solid Earth itself. This course looks at a dramatic example of solid Earth activity: earthquakes. You probably have some idea from newspapers, television or perhaps personal experience, of just how powerful earthquakes can be. In a matter of minutes earthquakes have devastated cities and killed a quarter of a million people. I was in only a medium-sized earthquake in 1978, but even that ha
Introduction Earthquakes shake the ground surface, can cause buildings to collapse, disrupt transport and services, and can cause fires. They can trigger landslides and tsunami – in short, earthquakes can be very destructive. In this unit you will look at why, where and what happens when they occur and also at how earthquakes are assessed qualitatively and quantitatively. 10.4 Summary By biological evolution we mean that many of the organisms that inhabit the Earth today are different from those that inhabited it in the past. Natural selection is one of several processes that can bring about evolution, although it can also promote stability rather than change. It follows that natural selection is not the same thing as evolution. The four propositions underlying Darwin's theory of evolution through natural selection are: (1) more individuals are produced than ca 1 Charles Darwin Charles Darwin (1809-1882) briefly studied medicine in Edinburgh before going to Cambridge intending to become an Anglican clergyman. Soon after the voyage of the Beagle (1831-1836), during which he was gentleman companion to Captain FitzRoy, Darwin became convinced that biological evolution had occurred and saw how it could have been brought about by natural selection. Despite having gathered massive amounts of supporting evidence, Darwin refrained from publishing his revolutio 1.4.7 T is for Timeliness The date when information was produced or published can be an important aspect of quality. This is not quite as simple as saying that 'good' information has to be up to date. Here is an example of a ne 3.1.1 (A) Science and certainty Pupils should appreciate why much scientific knowledge, particularly that taught in school science, is well established and beyond reasonable doubt, and why other scientific knowledge is more open to legitimate doubt. It should also be explained that current scientific knowledge is the best that we have but may be subject to change in the future, given new evidence or new interpretation of old evidence. 7 The jury The jury system has existed in Britain since the eleventh century, although its functions have changed over the centuries. The first juries very often acted as witnesses reporting on events they knew about. Modern juries should know as little as possible about the case before the trial and are mainly used in criminal trials in the Crown Court. Their role in the Crown Court is to listen to the evidence and decide the guilt or innocence of the accused based on the facts presented to them. They 5.2 Summary of Part D In Part D you have: examined how to read an Act of Parliament; studied the physical layout of Acts of Parliament and identified those features common to all Acts of Parliament; read sections of the Law Reform (Year and a Day Rule) Act 1996 and the Crime and Disorder Act 1998; examined the importance of Schedules and the short statement at the beginning of the Act; studied the language 4.13.1 Democratic accountability The main criticism of delegated legislation is that it takes law making away from the democratically elected House of Commons. Instead, power to make law is given to unelected civil servants and experts working under the supervision of a Government minister. 4.12 The advantages of delegated legislation The advantages of delegated legislation include the following: 4.11 Judicial control Delegated legislation is also subject to control by the courts whose judges can declare a piece of delegated legislation to be
ultra vires. Ultra vires means ‘beyond powers’, so the court would be saying that a piece of delegated legislation went beyond the powers granted by Parliament within the enabling Act. If the court does this, then the delegated legislation in question would be void and not effective. There are two types of ultra vires:
4.7 Court Rule committees Court Rule committees have delegated powers from such Acts as the Supreme Court Act 1981, the County Courts Act 1984 and the Magistrates’ Courts Act 1980, to make rules which govern procedure in particular courts. For example, the Criminal Procedure Rule Committee was established in 2004 to make rules of procedure for all the criminal courts in England and Wales, up to and including the Court of Appeal (Criminal Division). The Family Procedure Rule Committee was set up under the Courts Act 2.7 (iii) Royal Commissions Royal Commissions occasionally report to Parliament with recommendations for legislation which may be taken up as part of the Government's legislative programme. Royal Commissions are advisory committees established by the Government – though formally appointed by the Crown, hence the ‘Royal’ – to investigate any subject the Government sees fit to refer to one. They are often used for non-party political issues, or for issues that a Government wishes to be seen as addressing in a non- 3.2 Forms of business organisation, or ‘business mediums’ If you were to carry on the business described in Activity 2, you would be carrying on business on your own. You would be what is called a ‘sole trader’. We will look at the consequences of being a sole trader in a little bit more detail in this section. However, not all businesses are run by sole traders. There are several different ways in which 1 Making, interpreting and applying rules The aim of this unit is to introduce you to the processes of making, interpreting and applying rules. We often think about social rules, most of which are unwritten and which we observe because we have a shared social understanding of what they are. We are now going to think about a different kind of rule. A definition of a rule (as opposed to a habit, custom or role) is shown in Author(s): References Introduction Privacy has long been recognised as one of the important human rights and this is reflected in religion and history. There are, for example, references to privacy in the Qur'an, the Bible and Jewish law. Privacy was also protected in classical Greece and ancient China. The protection of privacy is seen as a way of drawing the line to indicate how far society can intrude into a person's affairs. Privacy encompasses an individual's liberty to choose how they lead their lives, freedom from 3.2 What is the European Convention on Human Rights? In the aftermath of the Second World War there were public disclosures of huge numbers of cases of brutal, inhuman and tyrannical treatment of people, frequently within the civilian populations of occupied countries. Many serious concerns arose about the way in which millions of people had been mistreated at the instigation of or with the connivance or concurrence of government. There was almost universal disgust and condemnation at the disclosures made, together with a general recognition th
