Geophysics to every area of the Earth sciences. To provide a clearer idea of what constitutes geophysics, this section describes phenomena that are studied in physics and how they relate to the Earth and its surroundings.

Therefore, there is a gap of 12 hours and 25 minutes between every high tide and between every low tide.
