Bending Moment vs Torsional Moment

In simple words, bending moment causes bending of the section, and Torsional moment (Torque) causes twisting of the section. If we talk about stresses induced, Due to torque-predominantly shear stress is induced in section and Due to bending - predominantly we have normal stresses.
Given a section and a moment is applied, then how do we decide that this moment is torque or bending moment?
It depends on the axis about which moment is applied. If the moment is applied about the longitudinal axis-it causes twisting of the section-then we call it torque and If we apply moment along the transverse axis-it causes bending of the section, then we can call it bending moment.
