Let us explain this properly, or at least as best I can without recourse to diagrams ... The earth is spinning around its axis once every 24 hours, and as a consequence is not the perfect sphere that it would be were this not so. The centrifugal effect of its spin throws its mass around the equator outwards which in turn draws in mass from the poles, so its spin makes it an 'oblate spheroid', a near sphere that bulges, has an increased radius, in the equatorial plane and contracts, has a reduced radius, in the polar plane, or put more simply its equatorial radius is somewhat bigger than its polar radius. This overall underlying shape is distorted daily by the moon's gravitational pull interacting with the earth's spin. Most of us are very familiar with the idea that the moon's gravity causes tidal bulges in the ocean on opposite sides of the earth, both towards the moon and away from it, but it also causes similar tidal bulges in the earth's solid structure. Because the earth is spinning, and it takes a material time for this tidal bulging to adjust, the bulge's axis is always slightly ahead of the line connecting the centres of the earth and moon. Hence the gravitational pull between the bulge and the moon is acting to pull the bulge 'backwards' in relation to the earth's spin and the moon 'forwards' in relation to its orbit. In other words, the earth's rate of spin is being gradually slowed by this 'tidal friction', while the moon's orbital speed is being gradually accelerated, which in turn increases the radius of its orbit, so the moon is gradually escaping the earth's gravity because it is slowly sucking the energy to do so out of the earth's spin. This applies equally to the moon also, which already tidal friction has slowed in its spin to the point that its period of spin is now equal to the period of its orbit, so it always shows almost the same face towards the earth - 'almost' because it still rocks slightly back and forth across the line of centres as its tidal bulge swings like a pendulum, all that is left now of whatever rotational energy of spin that it had when first the earth and moon became entrapped in their mutual gravity. A long time into the future, there will come a time when the earth's spin also will be slowed so much that it too will always show the same face to the moon. If my explanation above is not sufficiently clear, which it might not be due to the lack of diagrams, then this might help, or else do a search and choose a page or a video from a reputable source like a university: Why the Moon is getting further away from Earth https://www.bbc.co.uk/news/science-environment-12311119 -- Fake news kills!
