I would say the topic of such a study would be paleomagnetism and perhaps its effect on plate tectonics because when the seafloor spreads at the mid-ocean ridges, magnetized stripes of rock, symmetrical on either side of the trench form and they record changes in the earth's magnetic poles at certain times so can be dated to help show the rate of spreading of the seafloor at these locations.
Answer:
Beginning with Earth, then Jupiter, followed by Saturn, then Uranus, and finally Neptune
Explanation:
The distance of these planets from the sun is as follows. This is the average distance as the distance changes with the position of the planet in its orbit.
Earth = 150 million km
Jupiter = 779 million km
Saturn = 1.43 billion km
Uranus = 2.88 billion km
Neptune = 4.5 billion km
