Think more "mars-scape, marscape?", as the core also gives us our magnetic field that protects our atmosphere from the solar winds. Once the core cools, the Earth's internal dynamo also slows, solar winds start buffeting our atmosphere out of Earth's gravitational field, and we start looking more like Mars.
Also scheduled to happen around the same geologic time as the Earth being swallowed / burned by the Sun.

Yeah, several "what's gonna happen in unfathomable timescale" options to choose from.
