1.Read
and translate the text
The physical surface of the earth is the border between the solid or fluid masses and the atmosphere. The ocean floor has recently been included in the formulation of the geodetic problem, being the bounding surface between the solid terrestrial body and the oceanic water masses. The extension of the problem to the oceans is designated marine geodesy.
The majority of the observed parameters used in geodesy refers to the earth's external gravity field, whose study becomes a concern of geodesy.
The body of the earth and its gravity field are subject to temporal variations of secular, periodic, and singular nature, which can occur globally, regionally, and locally.
