Tidal Locking

QuestionAnswer
How long does it take the moon to rotate once? A month
What is synchronous tidal locking? When the same side of a moon always faces the planet
What type of moons in our solar system are tidally locked to their planets? Large moons
About how many orbits does it take a large moon to synchronize with their planets? Hundreds of thousands of orbits
How is it believed that the moon was formed? A massive object collided with Earth early in its history, splattering some of our planet into space.
What caused the moon to have a football shape after it was first formed? Earth's gravitational pull distorts the Moon's shape.
What caused the moon's rotation to begin slowing? The Earth's gravitational pull caused energy to dissipate/disappear from the moon and slowed down the moon's rotation.
How fast is the moon moving away from the Earth? Four centimeters (inch and a half) per year
The Earth's oceans move in response to the moon's gravity. What two things does the ocean's interactions with the moon cause? It creates friction that slows Earth's own rotation and creates forces that change the moon's orbital speed.
In about how many years will the Earth become tidally locked to the moon? About fifty billion years
When the Earth is tidally locked to the moon, who on Earth would be able to see the moon (if humans are still around)? One lucky half of our population
