Have you ever thought of living on Mars?
Our Earth is becoming more and more c
crowded
1.
And at the same time there's terrible p
pollution
2 here. If we move to Mars, things will probably change. However, it may be d
difficult
3 for people to have a conversation there, because sound doesn't travel very f
fast
4 on Mars. The low pressure(气压) makes it so. For example, a s
sound
5 by a human scream on the Earth can travel a little over a kilometre. But on Mars, the sound from that same scream will only move 15 metres at m
most
6. Besides, the atmosphere(大气) on Mars is also much t
thinner
7 than that on the Earth. On the Earth, our atmosphere is about 3 km t
thick
8, while it is very thin on Mars. Also the Earth has an e
even
9 higher temperature than Mars. The temperature on Mars is -87 ℃ to -5 ℃, so, are you r
ready
10 to go to Mars?
