Do tides occur in the open ocean?
In the open ocean, the water bulges out toward the moon. Along the seashore, the water rises and spreads onto the land. One high tide always faces the moon, while the other faces away from it. Between these high tides are areas of lower water levels—low tides.
How do tidal currents move water?
Tidal currents occur in conjunction with the rise and fall of the tide. The vertical motion of the tides near the shore causes the water to move horizontally, creating currents.
How do tides in the ocean work?
The moon's gravitational pull on the Earth and the Earth's rotational force are the two main factors that cause high and low tides. The side of the Earth closest to the Moon experiences the Moon's pull the strongest, and this causes the seas to rise, creating high tides.
Where are tidal currents strongest?
Saltstraumen is a small strait with one of the strongest tidal currents in the world. It is located in the municipality of Bodø in Nordland county, Norway. It is located about 10 kilometres (6.2 mi) southeast of the town of Bodø.

What causes a tidal wave?
A tidal wave is a shallow water wave caused by the gravitational interactions between the Sun, Moon, and Earth ("tidal wave" was used in earlier times to describe what we now call a tsunami.) A tsunami is an ocean wave triggered by large earthquakes that occur near or under the ocean, volcanic…
What forces are responsible for tidal currents?
Answer. Tidal currents are primarily driven by the gravitational interaction of the sun, moon, and Earth. They are also influenced by coastal topography. Tidal currents are the only type of currents that change regularly and can be easily predicted.

Why are tidal currents important?
Tidal currents also move floating animals and plants to and from breeding areas in estuaries to deeper waters. Oceanographers or atmospheric scientists may study tidal fluctuations to better understand the circulation of the ocean and its relationship to world climatic changes.

How do tides and waves work?
Waves transmit energy, not water, and are commonly caused by the wind as it blows across the ocean, lakes, and rivers. Waves caused by the gravitational pull of the moon and the sun are called tides. The ebb and flow of waves and tides are the life force of our world ocean.
Where do tidal waves occur?
Tidal waves are phenomena seen most at coastal areas. A majority of tsunamis (80%) occur in the Pacific Ocean but can occur in any large body of water if the underlying causes are present. Tidal waves occur daily at a coastal area.
What type of force is involved in the formation of tides in the sea?
Gravity is one major force that creates 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 is the major force behind surface currents in the open ocean?
What makes ocean currents flow? Tides contribute to coastal currents that travel short distances. Major surface ocean currents in the open ocean, however, are set in motion by the wind, which drags on the surface of the water as it blows. The water starts flowing in the same direction as the wind.
What force causes tides?
Gravity is one major force that creates 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).
How do tides help trade and fishing?
Tides help trade by making rivers navigable for trading ships. During high tide, the depth of water at the mouth of some rivers increase. This helps the ships to reach ports located on those rivers. Tides help the fishermen too.
How do waves form in ocean?
Most common are surface waves, caused by wind blowing along the air-water interface, creating a disturbance that steadily builds as wind continues to blow and the wave crest rises. Surface waves occur constantly all over the globe, and are the waves you see at the beach under normal conditions.
What causes tides to occur?
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.
Which activity leads to formation of tides?
(A) Tides caused by the sun and the moon during full moon (B) Changes in the tide caused by the sun and the moon (C) Changes in the tide caused by the combined gravitational pulls of the sun and the moon.
Which force is responsible for tides in the sea for Class 9?
the gravitational pull of moon Solution : It is the gravitational pull of moon on sea water.
What is the main driving force of the ocean’s surface currents of the deep circulation?
Wind is the primary driving force of surface currents. The Coriolis effect deflects the currents to the right (Northern Hemisphere) or left (Southern Hemisphere) of their path of motion (the prevailing wind direction).
What are the two main driving forces of ocean currents?
Oceanic currents are driven by three main factors:
- The rise and fall of the tides. Tides create a current in the oceans, which are strongest near the shore, and in bays and estuaries along the coast. …
- Wind. Winds drive currents that are at or near the ocean's surface. …
- Thermohaline circulation.

What is tidal action?
The side of the Earth that faces the Moon experiences a larger gravitational pull, due to the Moon's closer proximity, than other parts of the Earth. This force causes the Earth itself to bulge slightly toward the Moon.
How do tides help?
Strong tides help in the building of lower flood plains of rivers. These are very fertile. Since the debris is swept away by tides, they help to keep the harbours clean. In cold countries, tides bring in salt water to the shore and their continuous movement prevents the harbour from becoming ice bound.
How are tides and currents useful?
High tides help in navigation. This helps the ships to arrive at the harbour more easily. The high tides also help in fishing. Tides are also helpful in generating electricity.
What causes currents in the ocean?
Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. Currents are cohesive streams of seawater that circulate through the ocean.
What affects tides the most?
The moon is a major influence on the Earth's tides, but the sun also generates considerable tidal forces.
What type of forces involved in the formation of tides in the sea?
Gravity is one major force that creates 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).
Which force brings tide in ocean?
Gravity Gravity is one major force that creates 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).
Which of the following processes is responsible for driving most surface currents in the ocean?
Surface currents in the ocean are driven by global wind systems that are fueled by energy from the sun. Patterns of surface currents are determined by wind direction, Coriolis forces from the Earth's rotation, and the position of landforms that interact with the currents.
