![]() When the atmospheric resonance and length of day became even factors - 10 and 20 - the atmospheric tide was reinforced, the bulges became larger and the Sun’s tidal pull became strong enough to counter the lunar tide. Today, each of the two atmospheric ‘high tides’ take 22.8 hours to travel around the world because that resonance and Earth’s 24-hour rotational period are out of sync, the atmospheric tide is relatively small.īut during the billion-year period under study, the atmosphere was warmer and resonated with a period of about 10 hours.Īlso, at the advent of that epoch, Earth’s rotation, slowed by the moon, reached 20 hours. Throughout most of Earth’s history that atmospheric resonance has been out of sync with the planet’s rotational rate. The same principle explains why a bell always produces the same note if its temperature is constant. In other words, waves travel through it at a velocity determined by its temperature. The atmosphere, like a bell, resonates at a frequency determined by various factors, including temperature. But instead of slowing down Earth’s rotation like the moon, it speeds it up.”įor most of Earth’s geological history, the lunar tides have overpowered the solar tides by about a factor of ten hence, the Earth’s slowing rotational speed and lengthening days.īut some two billion years ago, the atmospheric bulges were larger because the atmosphere was warmer and because its natural resonance - the frequency at which waves move through it - matched the length of day. “The Sun’s gravity pulls on these atmospheric bulges, producing a torque on the Earth. “Sunlight also produces an atmospheric tide with the same type of bulges,” said University of Toronto theoretical astrophysicist Norman Murray. Moon and reflection images plus#The gravitational pull of the Moon on those bulges, plus the friction between the tides and the ocean floor, acts like a brake on our spinning planet. The Moon slows the planet’s rotation by pulling on Earth’s oceans, creating tidal bulges on opposite sides of the planet that we experience as high and low tides. Today, it continues to lengthen at a rate of some 1.7 milliseconds every century. When the Moon first formed some 4.5 billion years ago, the day was less than 10 hours long.īut since then, the lunar gravitational pull on the Earth has been slowing our planet’s rotation, resulting in an increasingly longer day.
