## Why these answers are right

**31. surface.** The first point is about what different processes affect. The lecturer says geography teaches us about the processes that have affected and continue to affect the Earth's surface. The note already says of the Earth, so the missing word is surface.

**32. environment.** The note mentions a dynamic between something and population. The lecturer speaks of relationships between a particular environment and the people that live there. Dynamic paraphrases relationships and population stands for the people, so the gap is environment.

**33. impact.** The second branch covers human lifestyles and something about them. The lecturer describes it as the study of the ways in which we choose to live and of the impact of those on our planet. Ways we live means lifestyles, so the gap is impact.

## Transcript

**Announcer:** Section 4, you will hear a lecturer's introduction to a geography module.

**Announcer:** First, you have some time to look at questions 31 to 40.

**Announcer:** Now listen carefully and answer questions 31 to 40.

**Speaker:** So, welcome to your introductory geography lecture.

**Speaker:** We'll begin with some basics.

**Speaker:** Firstly, what do we learn by studying geography?

**Speaker:** Well, we learn a great deal about all the processes that have affected and that continue to affect the Earth's surface, but we learn far more than that.

**Speaker:** Because studying geography also informs us about the different kinds of relationships that develop between a particular environment and the people that live there.

**Speaker:** OK, we like to think of geography as having two main branches.

**Speaker:** There's the study of the nature of our planet, its physical features, what it actually looks like.

**Speaker:** And then there's the study of the ways in which we choose to live, and of the impact of those on our planet.

**Speaker:** Our current use of carbon fuels is a good example of that.

**Speaker:** But there are more specific study areas to consider too, and we'll be looking at each of these in turn throughout the semester.

**Speaker:** These include biophysical geography.

**Speaker:** By which I mean the study of the natural environment and all its living things.

**Speaker:** Then there's topography, that looks at the shapes of the land and oceans.

**Speaker:** There's the study of political geography, and social geography too, of course, which is the study of communities of people.

**Speaker:** We have economic geography.

**Speaker:** In which we examine all kinds of resources and their use, agriculture for example.

**Speaker:** Next comes historical geography, the understanding of how people and their environments, and the ways they interact have changed over a period of time.

**Speaker:** And urban geography, an aspect I'm particularly interested in, which takes as its focus the location of cities, the services that those cities provide, and migration of people to and from such cities.

**Speaker:** And lastly, we have cartography.

**Speaker:** That's the art and science of map making, you'll be doing a lot of that.

**Speaker:** So, to summarize before we continue, we now have our key answer.

**Speaker:** Studying this subject is important, because without geographical knowledge, we would know very little about our surroundings.

**Speaker:** And we wouldn't be able to identify all the problems that relate to them.

**Speaker:** So, by definition, we wouldn't be in an informed position to work out how to solve any of them.

**Speaker:** OK, now for some practicalities.

**Speaker:** What do geographers actually do?

**Speaker:** Well, we collect data to begin with.

**Speaker:** You'll be doing a lot of that on your first field trip.

**Speaker:** How do we do this?

**Speaker:** There are several means.

**Speaker:** We might for example conduct a census, count a population in a given area, perhaps.

**Speaker:** We also need images of the Earth's surface which we can produce by means of computer generation technology, or with the help of satellite relays.

**Speaker:** We've come a very long way from the early exploration of the world by sailing ships.

**Speaker:** When geographers only had pens and paper at their disposal.

**Speaker:** After we've gathered our information, we must analyze it.

**Speaker:** We need to look for patterns, most commonly those of causes and consequences.

**Speaker:** 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.

**Speaker:** We then need to publish our findings, so that other people can access it and be informed by it.

**Speaker:** And one way in which this information can be published is in the form of maps.

**Speaker:** You'll all have used one at some stage of your life already.

**Speaker:** Let's consider the benefits of maps from a geographer's perspective.

**Speaker:** Maps can be folded and put in a pocket.

**Speaker:** And can provide a great store of reference when they're collected into an atlas.

**Speaker:** They can depict the physical features of the entire planet if necessary, or just a small part of it in much greater detail.

**Speaker:** But there is a drawback.

**Speaker:** You can't exactly replicate something that is three dimensional like our planet on a flat piece of paper, because paper has only two dimensions.

**Speaker:** And that means there'll always be a certain degree of distortion on a map.

**Speaker:** It can't be avoided.

**Speaker:** We can also use aerial photographs, pictures taken by cameras at high altitude above the earth.

**Speaker:** These are great for showing all kinds of geographical features that are not easy to see from the ground.

**Speaker:** You can easily illustrate areas of diseased trees, or how much traffic is on the roads at a given time, or information about deep seabeds for example.

**Speaker:** Then, there are landsats.

**Speaker:** These are satellites that circle the earth and transmit visual information to computers at receiving stations.

**Speaker:** They circle the earth several times a day.

**Speaker:** And can provide a mass of information.

**Speaker:** You'll all be familiar with the information they give us about the weather for example.

**Speaker:** So what we're going to do now is look at a short presentation in which you'll see all these tools.

**Announcer:** That is the end of Section 4.

**Announcer:** You now have half a minute to check your answers.
