3. hydrosphere: the portion of the earth covered by water

Explanation:

Astronomy is concerned with celestial objects, space and the physical universe as a whole. Geology involves the study of the physical structure and substance of the earth, as well as its history and the movements that act on it. Hydrosphere refers to all the waters on the surface of the earth, such as lakes and seas, and sometimes to water over the surface of the earth, like clouds. Meteorology studies the processes and phenomena of the atmosphere, especially as a means of predicting the weather. Oceanography covers the physical and biological properties and phenomena of the sea.
