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?

In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth (Sumich, J.L., 1996).

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.

What created the tides?

       Tides are very long waves that move across the    oceans.They are caused by the gravitational forces exerted on the earth by the moon, and to a lesser extent, the sun. When the highest point in the wave, or the crest, reaches a coast, the coast experiences a high tide

How many tides occur daily?

While some places have one high tide and one low tide per day, most coastal locations have two high tides and two low tides a day.

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.

How fast is a tide?

Because the Earth rotates through two tidal “bulges” every lunar day, coastal areas experience two high and two low tides every 24 hours and 50 minutes. High tides occur 12 hours and 25 minutes apart. It takes six hours and 12.5 minutes for the water at the shore to go from high to low, or from low to high.

When was the deepest part of the ocean discovered?







. 23, 1960

15, 1959. On Jan. 23, 1960, Walsh and Piccard made history when they made the five-hour, 6.78-mile odyssey to the world's deepest-known point.

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.

 Where is the biggest tide in the world?


Bay of Fundy
Located in Canada, between the provinces of Nova Scotia and Brunswick, sits the Bay of Fundy, home to the world largest tidal variations.

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?

Tides churn up material in the oceans, which allows coastal ecosystems to thrive. Animals in these environments – crabs, mussels, starfish, snails – rely on the tides for survival. Without a coastal ecosystem, this could have knock-on effects for other land and sea animals and could lead to mass extinctions.
