Listening Full Test 1 - Section 4





So, welcome to your introductory geography lecture. We’ll begin with some basics. Firstly, what do we lean by studying geography?

Well, we learn a great deal about all the processes that have affected and that continue to affect the earth’s surface (Q31). But we learn far more than that, because studying geography also informs us about the different kinds of  relationship that develop between a particular environment (Q32) and the people that live there.

Okay. We like to think of geography as having to main branches. There’s the study of the nature of our planet – its physical features, what it actually looks like – and then there’s the study of the ways in which we choose to live and of the impact (Q33) of those on our planet. Our current use of carbon fuels is a good example of that.

But there are more specific study areas to consider too, and we’ll be looking at each of these in turn throughout this semester. These include bio-physical geography, by which I mean the study of the natural environment and all its living things. Then there’s topography – that looks at the shapes of the land and oceans. There’s the study of political geography and social geography too, of course, which is the study of  communities of people. We have economics – in which we examine all kinds of resource and their use – agriculture, for example. Next comes historical geography – the understanding of how people and their environments and the ways they interact have changed over a period of time – and urban (Q34)geography, an aspect I’m particularly interested in, which takes as its focus the location of cities. And lastly, we have cartography. That’s the art and science of map-making. You’ll be doing a  lot of that!

So, to summarise before we continue, we now have our key answer…studying this subject is important because without geographical knowledge, We would know very little about our  surrounding and we wouldn’t be able to identify all the problems (Q35) that relate to them. So, by definition, we wouldn’t be in an informed position to work out how to solve many of them.

Okay, now for some practicalities. What do geographers actually do? Well, we collect data to begin with! You’ll be doing a lot of that on your first field trip! How do we do this? There are several means. We might, for example, conduct a census – count a population in a given area perhaps. We also need images (Q36) of the earth’s surface which we can produce by means of computer – generation technology or with the help of satellite relays. We’ve come a very long way from the early exploration of the world by sailing ships when geographers only had pens and paper at their disposal.

After we’ve gathered our information, we must analyse it! We need to look for patterns (Q37), most commonly those of  cause and consequences. This kind of  information, we must analyse it! We need to look for patterns, most commonly those of causes and consequences. This kind of  information helps us to predict and resolve problems that could affect the world we live in.

But we don’t keep all this information confidential. We then need to publish our findings so that other people can access it and be informed by it. And one way in which this information can be published is in the form of maps. You’ll all have used one at some stage of your life already. Let’s consider the benefits of maps from a geographer’s perspective.

Maps can be folded hand put in a pocket and provide a great store of reference when they’re collected in an atlas. They can depict the physical features of the entire planet if necessary, or , just a small part of  it in much greater detail. But there is a drawback. You can’t c exactly replicate something that is three-dimensional, like our planet, on a flat piece of paper, because paper has only two dimensions, and that means there’ll always be a certain degree of distortion (Q38) on a map. It can’t be avoided.

We can also use aerial photographs…pictures taken by cameras at high altitude above the earth. These are great for showing all kinds of geographical features that are not easy to see from the ground . You can easily illustrate areas of  diseased trees or how much traffic (Q39) is on the road at a roads at a given time or information about deep sea beds, for example.

Then there are Landsats. These are satellites that circle the earth and transmit visual information to computers at receiving stations. They circle the earth several times day and can provide a mass of  information – you’ll be familiar with the information they give us about the weather (Q40) , for example.

So, what we’re going to do now is look at a short presentation in which you’ll see all these tools…
