bathymetry -the measurement of water depth at various places in a body of water.

rock in outcrop, samples brought to the surface from greater depths by

volcanic activity, analysis of the seismic waves that pass through Earth, measurements of the gravity field of Earth, and experiments with crystalline solids at pressures and

temperatures characteristic of Earth's deep interior.
