Question 1

Which of the following is true regarding the Moho?

Accepted Answer

A) It is a type of boundary representing an almost imperceptible transition from one type of rock to another that is virtually identical in composition. 
B) It is smooth,like the surface of a sphere. 
C) It mirrors the surface topography i.e. ,high places on the surface of Earth overlie areas in which the Moho descends to greater depths,and vice versa. 
D) It parallels the surface topography,which means that the Moho always lies at the same depth below the surface. 
E) The Moho lies at the boundary between the upper mantle and the aesthenosphere.
