On Lunar and Solar tides: a few informative tweets by Neil deGrasse Tyson (or: Why the hell do we have higher tides during a full moon?! It makes no sense!)
- While we’re on the subject: The Moon’s capacity to raise tides on Earth is no greater when Full than at any other phase.
- The tides during Full (and New) Moon are highest **only** because that’s when the Sun’s tides add directly to them.
- During half-moons (1st & 3rd quarter), the Lunar & Solar tides add out of phase, partly canceling one another.
- The Sun’s tides are only about 1/3 that of the Moon’s, so even during the canceling quarter phases, some Moon-tide remains.
- And not to disturb anybody, but Tides cause friction between Earth’s crust and the sloshing oceans, slowing down our rotation.
- Not only is Earth’s rotation slowly slowing down, but the Moon’s orbit is spiraling away from us by about 2-inches per year.
