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. The gravitational pull of the Moon and Sun give rise to two high tides and two low tides every lunar day, or every 24 hours and 50 minutes. Therefore, there is a gap of 12 hours and 25 minutes between every high tide and between every low tide. Gravitational forces make rocks press down on deeper rocks, increasing their density as the depth increases. Measurements
Pokémon Sun and Moon the franchise in general and that they were working to develop interactivity between the app and the main series. Ohmori added that during the development of "Sun and Moon" they "completely redesigned the system, and actually ended up pushing the 3DS even further to what [they] thought was the most [they] could draw out of it." With a team of around 120, the games took about three years to develop, comparable with other new-generation games. Later on, Kazumasa Iwao, who was responsible for the battle systems in "Sun and Moon", was recruited as director for "Ultra Sun and Ultra Moon".
