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 …
Yes, I do some people have though live on the Mars but in my opinion it's impossible live out on the earth becaues the earth planet created for us.the earth planet has everything for live human on it.
No, I don't think people will live on Mars one day. Because of carbon dioxide for breathing and cold weather than the Earth.
I think this is a good listening to improve your skills
I think so, since they're very similar planets, but NASA is still doing more research on Mars.
In my point of view, I believe people will be able to travel to Mars in the near future due to advancements in technology. However, I don't think they will choose to live there permanently because of challenges like the lack of oxygen and extremely cold weather. In conclusion, Earth will remain the best place for humans to live, even if more options become available in the future.
Hello I like that lesson and your your support to enhance our English Language
Yes I do. I think people will live on Mars because Mars and Earth have similar facts such as support human life, having water but Mars are colder than Earth that why people need to consider this fact. Another important point to noticed that we need more advanced technology, high infrastructure, and higher cost.
Yes, I do. I think people will live on Mars one day, but at a high cost. This is because of the lack of oxygen and all the differences from Earth discussed above. By 'high cost,' I mean the significant amount of resources that will be needed to make life there possible.
The life between Earth and Mars has different challenges. While the Earth's atmosphere is composed of Nitrogen, Oxygen, and an electromagnetic field to protect from solar storms and the Ozone layer, Mars has no atmosphere an electromagnetic field to protect from Solar storms and the ozone layer. Another big challenge is the lack of vegetation due to Mars does not atmosphere to preserve life.
I think the biggest challenge of living on Mars is the lack of air. We need oxygen to live, but Mars doesn’t have any oxygen for us to breathe
