Today in period 4 we did Science. We are learning about the atmosphere, we have a set of questions to answer about the atmosphere.
1. What are two reasons, Mercury lost most of its the atmosphere?
The planet's small size means that its gravity is too weak to hold down a normal atmosphere.
2. Compare how close Mercury and Earth to Sun.
There is one planet between Mercury and Earth, Mercury is the first planet and Earth is the third planet.
3. Compare how much mass Mercury and Earth have.
Earth: 5.972 x 10^24 kg and Mercury: 3.285 x 10^23 kg (0.055 M⊕)
4. How does not having an atmosphere affect the temperature on Mercury.
The lack of atmosphere also contributes to the planets wild temperature extremes.
