High tides occur 12 hours and 25 minutes apart. It takes six hours and 12.5 minutes for the water at the shore to go from high to low, or from low to high.]]> 2018-10-05 18:20:53 UTC https://padlet.com/phacal516/rz4ycdvbnrl0/wish/289771463 phacal516 https://padlet.com/phacal516/rz4ycdvbnrl0/wish/289773605 They are Neap tides and Spring tides.]]> 2018-10-05 18:24:59 UTC https://padlet.com/phacal516/rz4ycdvbnrl0/wish/289773605 phacal516 https://padlet.com/phacal516/rz4ycdvbnrl0/wish/289781239 What is gravity?
-A force that attracts a body toward the center of Earth
Why is a tidal force important?
-Tides cause changes in the depth of the sea, and also produce oscillating currents known as tidal streams, making prediction of tides important for coastal navigation.
