Through friction, this flexing produces heat in the moon's interior capable of melting ice.
通过摩擦，这种弯曲在月球内部产生了能够融化冰的热量。

Prior to 1965 geologists assumed that the two giant rock plates meeting at the San Andreas Fault generate heat through friction as they grind past each otherd.
1965年以前，地质学家认为，两个巨大的岩石板块在圣安德烈亚斯断层上相遇，通过摩擦产生热量。

Some geologists wondered whether the absence of friction-generated heat could be explained by the kinds of rock composing the fault.
