A semi-analytic approach is developed for dealing with the tau-lepton flux emerging from the Earth, induced by the incident high energy tau neutrinos interacting inside the Earth for 105 ≤ Eν/GeV ≤ 1010. We obtain results for the energy dependence of the tau-lepton flux coming from the Earth-skimming neutrinos due to the neutrino-nucleon charged-current interaction. We illustrate our results for several anticipated high energy astrophysical neutrino sources such as the AGNs, the GRBs, and the GZK neutrino fluxes. The tau lepton fluxes resulting from rock-skimming and ocean-skimming neutrinos are compared. Such comparisons might render useful information for the spectral indices of incident neutrino fluxes.
