Why are tides formed inspite of earths gravitational pull?
Your right, the earth’s gravitation pull is more. But think of the difference of gravitational pull on the side of the earth the moon is on compared to the other side. For arguments sake, lets say the earth’s gravitational pull is 15 Newtons (i know its not even close) with no moon. On the other side its 15 Newtons minus the gravitational pull of the moon. So yes, the earth’s gravity is stronger, but the moon weakens it compared to the other side of the earth.
The tides are the result of the small, but variable, gravity of the Moon adding to the large, but constant, gravity of the Earth. It’s not like the ocean is leaping up in the sky when the Moon is overhead—it’s still held down to the Earth, just a little bit more weakly than before, and so in the whole vast ocean, thousands of meters deep, the level changes maybe one meter.
The Moon (Latin: Luna) is Earth’s only natural satellite and the fifth largest natural satellite in the Solar System. The average centre-to-centre distance from the Earth to the Moon is 384,403 km, about thirty times the diameter of the Earth. The Moon’s diameter is 3,474 km,[6] a little more than a quarter that of the Earth. This means that the Moon’s volume is about 2 percent that of Earth and the pull of gravity at its surface about 17 percent that of the Earth. The Moon makes a complete orbit around the Earth every 27.3 days (the orbital period), and the periodic variations in the geometry of the Earth–Moon–Sun system are responsible for the lunar phases that repeat every 29.5 days (the synodic period). The Moon is the only celestial body to which humans have travelled and upon which humans have landed. The first artificial object to escape Earth’s gravity and pass near the Moon was the Soviet Union’s Luna 1, the first artificial object to impact the lunar surface was Luna 2, and t
