it is...Earth!
what role does the moon do on tides
The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.
how deep is the ocean?
The average depth of the ocean is 3,700 meters (12,100 feet) But the deepest part ever recorded is located in the western part of the Pacific Ocean! in the Mariana Trench, at a depth of around 11,000 meters (36,200 feet). Bathymetry is the scientific term for measuring the depth of water in oceans, lakes and rivers!
Who first discovered tides?

The sun's gravitational force on the Earth is only 46 percent that of the Moon;
how old are the planets
Earth is 4.543 billion years old. Sun,Saturn,Mercury,Venus,Uranus, 4.503 billion 4.603 billion years old.Mars,Jupiter.
what role does the sun do to the tides
When the sun, moon, and Earth are in alignment (at the time of the new or full moon), the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides—both commonly called spring tides.
who first found the deepest ocean
The first and only time humans descended into the Challenger Deep was more than 50 years ago. In 1960, Jacques Piccard and Navy Lt. Don Walsh reached this goal in a U.S. Navy submersible, a bathyscaphe called the Trieste.

Has anyone ever found the bottom of the ocean?
On 23 January 1960, two explorers, US navy lieutenant Don Walsh and Swiss engineer Jacques Piccard, became the first people to dive 11km (seven miles) to the bottom of the Mariana Trench. As a new wave of adventurers gear up to repeat the epic journey, Don Walsh tells the BBC about their remarkable deep-sea feat.
Do rivers have tides?
Some freshwater rivers and lakes can have tides, too. A high tide that is significantly higher than normal is called a king tide. It often accompanies a new moon and when the moon is closest to the Earth.

Why do we need tides?
Tides are very important in controlling the depth and flow of water to help ships navigate easily near the shores. Using the advantage of water level and current of water during high tides, the ships can reach the harbor conveniently.

Why can't we go to the bottom of the ocean?
The intense pressures in the deep ocean make it an extremely difficult environment to explore.” Although you don't notice it, the pressure of the air pushing down on your body at sea level is about 15 pounds per square inch. If you went up into space, above the Earth's atmosphere, the pressure would decrease to zero.
What if there were no tides?
