What is the significance of measuring the change in 'g' due to depth?
It helps to understand the structure and composition of the Earth's interior
It helps in predicting earthquakes
It helps in designing deep sea exploration vehicles
It has no practical meaning
Measuring the change in 'g' due to depth is important for understanding the structure and composition of the Earth's interior. By studying how "g" changes with depth, scientists can gain insight into the density and composition of Earth's various layers, which in turn can help us better understand how Earth has formed and evolved over time. This information can also be useful for predicting seismic activity and for designing exploration vehicles for deep-sea and subsurface environments.
