Question

Which of the following would increase the effect of tides on Earth (high tides get higher, low tides get lower)
- slowing the rate of rotation of the Moon.
- increasing the rate of rotation of the Moon. ***
- decreasing the distance between the Earth around the Sun
- increasing the rate of revolution of the Earth around the sun

Answer 1

The rate of rotation of the moon about its axis, once per earth day, has no effect on the tides on earth.

Moving the moon orbit closer to earth would do it though.

Is there no choice called "none of the above"?

Answer 2

no there isn't. :/

Answer 3

Then I think this is a typo:

" decreasing the distance between the Earth around the Sun "

and it means distance between earth and moon

Answer 4

Yeah one is supposed to say "Decrease the distance between the Earth and the Moon" Which is the right one
