S283: TMA-1

Well compared to the chemistry I'm doing alongside this, I find this TMA reasonably easy. Possibly too easy as I get a less than expected mark for it. That will teach me!
Lets see - what does it have in store?

Question 1 is about the formation of the solar system. When it formed, why rocky planets are in the inner and gas giants in the outer. Stuff about ring systems and density, and the asteroid belt. Not too bad for a start.

Question 2 is geology. What the structure of the earth is, what the layers are, how they are defined and stuff like that. Some bits on mineralogy and seismic data, and rounded off with xenoliths and what they can tell us about the structure.

Question 3 looks at various moons, and gets you to fill in a table. How old is the surface of each, what if any caused the resurfacing, and what was it made up of. Then you are given data about two imaginary satellites, and asked to work out from density and other information what sort of body they are likely to be.

Question 4 is about volcanism and cryovolcanism. What basalt is so common, what makes it so and so on. More geology...

Question 5 is interesting, as you are given a picture of part of the moon, and have to work out various dimensions of the craters pictured, and then determine if they are simple or complex craters. I found acrobat reader has a great tool for this sort of measuring. Then you have to make various observations and hypotheses about the craters such as age and relative order.
