Answer:
C. Principle of original horizontality
Explanation:
The Law of Original Horizontality suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed. This allows us to infer that something must have happened to the rocks to make them tilted.
These two theories are related because they are continuity from one another. The theory of plate tectonics insinuates that the crust layer is broken into multiple pieces, this is caused by the pressure of the mantle layer, which managed to break the crust where it is thinner. The theory of continental drift insinuates that the tectonic plates move around the Earth because of the pressure from the hot semi-liquid mantle layer.
If you mean Fahrenheit and Celsius, than 16 F is greater than 16 C
