Book Review: High Tide, Low Tide


Written by Jason Cooperz

Do you know how gravity makes tides? I read a book called High Tide, Low Tide by Jason Cooper and learned that there are different types of tides and that gravity pulls them.

I thought the best part of the book was when it talked about how tall high tide got in Canada. The book says that in the Bay of Fundy in Canada, “High tides are about 39 feet (12 meters) higher than the low tide.” The moon, the sun, and the earth, all have gravity that pulls the water. Therefore, gravity from the Earth, sun, and moon, tug against each other, causing the tides to rise and fall. When the tides rise, this is called high tide; when it lowers, it is called low tide. When the earth moves, it weakens the sun’s and moon’s gravity which causes the tides to change.
