What is the simplest meaning of discontinuity?

Answer and explanation

Correct answer: Change boundary between two internal layers

The direct answer is B: a discontinuity is a boundary where the properties of two internal layers change. In Earth science, a layer may change in composition, density, state or the speed of seismic waves. Reasoning: Earth has internal layers; the material in one layer is not always like the material in the next; the transition zone is called a discontinuity; seismic waves may change speed or direction there. A is wrong because a forest is a surface feature, not an internal boundary. B is correct. C is wrong because ocean-water colour has nothing to do with Earth’s internal layering. D is wrong because air pressure is an atmospheric idea, not the meaning of a geological discontinuity. Examples include the Moho and core-mantle boundary, but the simple exam meaning is a change boundary between layers. Memory cue: discontinuity means a break or change in continuity.
