What could be the (geological) reason that Mars lost much of its magnetic field?
Instructions
The following questions need to be answered in the form of a short paragraph. The research that you need to do replaces the labs of the coming weeks (until further notice).
You will work in groups of 2 (not more), the reported answers need to be handed-in 1 week after the respective lab. The text MAY NOT be copied and pasted, you will have to write in your own language – If you don’t, you and your lab partner may loose valuable points. Also do not use Google Translate from Arabic to English! This will produce text that is quite often complete rubbish. If you feel that your language skills are not good enough, ask your lab partner to assist (that way, you will also improve your English).
Lab Questions
Q1: What could be the (geological) reason that Mars lost much of its magnetic field?
Q2: Which other physical factor may have contributed to the loss of the Martian atmosphere? And why could the gas atoms disappear into interstellar space?
Q3 With respect to Jupiter and Saturn, I mentioned a metallic hydrogen layer and you all know that hydrogen is not a metal. So, what is the definition of a metal and how can we apply that to hydrogen?
Q4: How can we generate a magnetic field, when there is no Iron-Nickel core of the giant outer planets? Re-examine the previous question.
Q5: Asteroids, and comets are considered remnants from the giant cloud of gas and dust that condensed to create the sun, planets, and moons some 4.5 billion years ago. Where did all this dust come from?
