Tides are capable of slowing the Earth’s rotation by the following force:a
Tidal friction
b. Gravitational forces
c. Resonance
d. Centrifugal forces
ANS: A
The daily rise and fall of the tides consumes a large amount of energy and this is ultimately dissipated
as heat. Most of this energy comes from the rotation of the Earth itself, and tidal friction is gradually
slowing the Earth’s rotation by a few hundredths of a second per century. Information can be found in
the section Tidal Friction Slows the Earth’s Rotation
