Question

Say we discover two new planets -- Sram and Noom. They are both believed to have a core of rock surrounded by a mantle of ice. They are the same size but Sram has a mean density of 2800 kg/m3 and Noom has a density of 1400 kg/m3.

8) Which has the thinner mantle of ice, Sram or Noom? Explain why.

9) Yrucrem has the same mean density (2800 km/m3) as Sram but Yrucrem has a radius half that of Sram. Which planet will have cooled faster?

10) What would be the evidence that you would look for on the surfaces of Sram and Yrucrem to confirm your hypothesis of which planet had cooled first?

Explanation / Answer

8) Noom - the higher density but same size of Sram means that it has a larger rocker core hence smaller mantle of ice

9) smaller planet cools faster = Yrucrem

10) the density of impact craters would be higher on Yrucem
