WebIn addition, the presence of water in rock tends to make it more ductile and less brittle. Temperature—Rocks become softer (more ductile) at higher temperature. Rocks at mantle and core temperatures are ductile and will not fracture under the stresses that occur deep within the earth. WebMantle and crust are composed of dra-matically different rock with very different seismic properties. The 6- to 80-km-thick crust floats atop the mantle. The depth of the crust-mantle boundary, or “Moho,” is related to surface topography and ongoing tectonic deformation. Converging plates create thick crust and high mountains,
