Query: Mercury, Moon, Mars: Surface expressions of mantle convection and
  interior evolution of stagnant-lid bodies   The evolution of the interior of stagnant-lid bodies is comparatively easier
to model and predict with respect to the Earth's due to the absence of the
large uncertainties associated with the physics of plate tectonics, its onset
time and efficiency over the planet's history. Yet, the observational record
for these bodies is both scarcer and sparser with respect to the Earth's. It is
restricted to a limited number of samples and a variety of remote-sensing
measurements of billions-of-years-old surfaces whose actual age is difficult to
determine precisely. Combining these observations into a coherent picture of
the thermal and convective evolution of the planetary interior represents thus
a major challenge. In this chapter, we review key processes and (mostly
geophysical) observational constraints that can be used to infer the global
characteristics of mantle convection and thermal evolution of the interior of
Mercury, the Moon and Mars, the three major terrestrial bodies where a stagnant
lid has likely been present throughout most of their history.
