  This paper reviews habitability conditions for a terrestrial planet from the
point of view of geosciences. It addresses how interactions between the
interior of a planet or a moon and its atmosphere and surface (including
hydrosphere and biosphere) can affect habitability of the celestial body. It
does not consider in detail the role of the central star but focusses more on
surface conditions capable of sustaining life. We deal with fundamental issues
of planetary habitability, i.e. the environmental conditions capable of
sustaining life, and the above-mentioned interactions can affect the
habitability of the celestial body. We address some hotly debated questions
including: - How do core and mantle affect the evolution and habitability of
planets? - What are the consequences of mantle overturn on the evolution of the
interior and atmosphere? - What is the role of the global carbon and water
cycles? - What influence do comet and asteroid impacts exert on the evolution
of the planet? - How does life interact with the evolution of the Earth's
geosphere and atmosphere? - How can knowledge of the solar system geophysics
and habitability be applied to exoplanets? In addition, we address the
identification of preserved life tracers in the context of the interaction of
life with planetary evolution.
