the principal of ____ states that in rock layers that have not been folded or deformed, the oldest rock layers are at the bottom.\ngeomorphology\nsuperposition\nradioactivity\nstratigraphy\n\na push or pull on an object is known as ____.\nmass\nforce\ngravity\nmomentum\n\nelectricity and gravity are both examples of a ____ force.\ncontact\nnon - balanced\nnon - contact
Answer
Brief Explanations:
- 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.
- 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.
- 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:
- B. Superposition
- B. Force
- C. Non - contact
