Answer

Brief Explanations:

  1. The principle of superposition in geology states that in undeformed rock - layers, the oldest are at the bottom. Geomorphology is about land - form study, radioactivity is about decay processes, and stratigraphy is the study of rock layers in general but not specifically this principle.
  2. A push or pull on an object is defined as force. Mass is the amount of matter in an object, gravity is a type of force related to mass, and momentum is the product of mass and velocity.
  3. Electricity and gravity are non - contact forces as they can act on objects without physical contact. Contact forces require physical touch, and non - balanced refers to a state of forces not being equal, not the nature of these forces.

Answer:

  1. B. Superposition
  2. B. Force
  3. C. Non - contact
