TEXT: COMPARING ATMOSPHERE
You are a person on Earth. You breathe in our atmosphere, the gases that surround Earth. There is 78% nitrogen, 21% oxygen, with some other gases. Because you need oxygen, Earth is a great place to breathe. Our atmosphere blocks radiation from the Sun.
There is very little atmosphere on the Moon, and definitely not enough oxygen. The Moon’s weak magnetic field can’t keep gas in place well. Dangerous radiation from the Sun is not blocked. Without a special suit, your body would be damaged.
The Sun’s atmosphere is deadly to you. The Sun is all gas and so are its layers of
atmosphere: the photosphere, chromosphere, and the outer corona. Sunspots and
solar flares happen in the photosphere, where the Sun’s energy is released as light. Hydrogen is burned off in the super-hot chromosphere. The corona flares out into space at a
temperature of more than 3 million degrees F. No living thing would survive the Sun.
