A student discussion

Listen to two students comparing Mars and Earth to practise and improve your listening skills.

Instructions

Do the preparation task first. Then listen to the audio and do the exercises.

Transcript

Teacher: So you've got a few minutes to discuss with your partner.

Student 1: So, as far as I know, the main similarity between Mars and Earth is that they can both support human life.

Student 2: Yeah, but do we know that's actually true? I mean, Mars is much colder than Earth, isn't it? It says here it's about minus 55 degrees most of the time, whereas on Earth only places like Antarctica get that cold.

Student 1: True. Well then, I suppose you could say both planets are a similar distance from the Sun?

Student 2: No way! Mars is much further away! It says here it's about 228 million kilometres, while Earth is about 150 million.

Student 1: Yes, but in space that's not that far. Jupiter is, like, almost 780 million kilometres. That's why we use astronomical units when we talk about distances in space. Earth is 1 astronomical unit from the Sun and Mars is 1.3. The difference doesn't sound so big when you look at it that way.

Student 2: I see what you mean. Jupiter is 5.2 astronomical units so I guess you're right. What other similarities are there between the two planets?

Student 1: Let's see … not the colour, obviously!

Student 2: Yeah! Earth is called the blue planet and Mars is called the red planet for pretty obvious reasons!

Student 1: Their sizes are pretty different. Mars is about half the size of Earth.

Student 2: What about this? It looks like the days on both planets are almost the same length. Earth's day is 24 hours but Mars's is about half an hour longer.

Student 1: You're right. OK, any other things they both share?

Student 2: I suppose you could say they have water in common.

Student 1: Could you? How?

Student 2: Well, Earth is 70 per cent water and Mars probably had huge oceans in the past. It's just that most of the water there now is probably frozen.

Student 1: Ah, I see. I don't think we can say the air is the same, though. Most of Earth's air is nitrogen and oxygen, but Mars …?

Student 2: Mars doesn't really have air, not compared with Earth. It's got about one per cent as much air as Earth.

Student 1: Right, and it's mostly carbon dioxide.

Student 2: Gravity is another difference. I didn't know this, but Mars has higher gravity than the Moon. But it's much less than on Earth, of course.

Student 1: Oh, yes. It says Mars has about 38 per cent of Earth's gravity.

Teacher: OK, let's see what you've found …

I think it is possible that people move to another planet or appear in another planet. Because of species evaluation, everything is possible.

I don't think people will live on Mars one day. People have to cover up around Mars with oxygen. To be honest It seems like it will be with current technologhy.I hope to buy field in Mars in the future.

I think they can.Now science is so developed and may be it will be possible to make the right conditions for life on Mars later.But I wish they could save the Earth first...

In my opinion it won't be possible soon. There are should be many advances to reach it.

Now it is very difficult to say! The technology is grow every day. And may be whenever people will on the Mars!

I believe that the human will live on Mars, when it is will be economically interesting for bigger companies in the Earth.

Hello dear, the British Council team One of the requirements for traveling to Mars is access to highly equipped rockets to protect passengers from radiation that is very harmful to their bodies. I think people will live on Mars on the future, but in different physical capacities or situations. Mars is very different from Earth. carbon dioxide is much larger than Earth. the weather degrees are in -55 degrees, so its waters are frozen because its farther from the sun. there isn't any suitable air in it so it's so hard to live in. It is very difficult to reach the mars because there are much more ion rays around it. It may be possible for people to live on it in future but not for us . Different people in different physical systems. Best Wishes Mehrzain

definitlly .I dont think that..

Of course. Actually we have the technology to support life there. We have the issue of develop travel whit ships that could be reused, because that is important in terms of the mission costs. Ironically we find the way for support the life in Mars but don’t in earth when the use of natural resources exceed the capacity of regeneration
