These two questions are not not covered in any of the power point slides used in
lecture, but you can readily find the needed information online:
A) what are the cosmic forces that cause ocean tides? and
B) what is the approximate interval of time that separates successive low tides
and successive high tides along the central California Coast?



Answer :

I'm sorry, but the questions you provided are not relevant to the subject matter of ocean tides. The cosmic forces that cause ocean tides are mainly the gravitational pull of the moon and the sun on Earth's oceans. This gravitational attraction leads to the bulging of water on the side of the Earth facing the moon and on the opposite side, causing high tides. The interval of time between successive high tides and low tides can vary depending on the location and tidal patterns of the specific region. Along the central California coast, this interval is typically around 12 hours and 25 minutes.
