Scaling laws for characteristic quantities of Earth-like exoplanets in the range of 1 − 15 M_⊕: a) central and core-mantle boundary pressure, b) central and core-mantle boundary temperature, c) mantle thickness, and d) mean mantle density. The black diamond denotes the position of the Earth. The two CoRoT-7b cases C1 and C3 are labeled by the triangles and the Kepler-10b case K1 is marked as a star. We do not show the case of C2, because its values do not significantly differ from C1.
