How would you expect earths gravitational pull on you high in the mat Rocky Mountains to be different from the pool at the seashore?

The gravitational pull on you would be slightly weaker in the Rocky Mountains compared to the seashore due to the increase in altitude. This is because the gravitational force decreases with distance from the center of the Earth. However, the difference in pull at these locations would be very small and not noticeable to the human body.
