Tides are caused due to the strong gravitational pull exerted by the sun and moon on the earth's surface. High tides help in navigation and fishing. The rise and fall of water due to tides is being used to generate electricity in some places The strong gravitational pull exerted by the sun and the moon on the earth's surface cause the tides. (f) Ocean currents are streams of water flowing constantly on the ocean surface in definite directions. Q. 2
The strong gravitational pull exerted by the sun and the moon on the earth's surface cause the tides. The water of the earth closer to the moon gets pulled under the influence of the moon's gravitational pull that causes tides. Question 2. Tick the correct answer It is caused by the combined effects of the gravitational forces exerted by the Moon and the Sun and the rotation of Earth Tides can worsen damage and erosion caused by storm waves, but they can also provide tidal power, which is energy obtained from the rise and fall of tides. Learning Outcomes When you have finished. Tides are caused by the strong gravitational pull exerted by the Sun and the Moon on the Earth's surface. Formation of high and low tides: The water of the Earth closer to the Moon gets pulled under the influence of Moon's gravitational force, thereby causing a rise of ocean water towards the Moon A discussion of tides and their patterns follows the creation and examination of their graphs. They learn the difference between a diurnal, semidiurnal, and mixed semidiurnal tide, and then interpret unusual tides from different locations around the world. Investigation 4: Temperature and Salinity Effects on Deep Ocean Currents (7-9 days
The following pages describe the tremendous forces that cause the world's tides, and why it is important for us to understand how they work. This animation shows the relationship between the vertical and horizontal components of tides. As the tide rises, water moves toward the shore. This is called a flood current Tides are the rise and fall of sea levels around the world. There are two high tides and two low tides each day. The size of the high and low tides change over the month. During a full moon or a.
Tides may be high or low. It is high tide when water covers much of the shore by rising to its highest level. It is low tide when water falls to its lowest level and recedes from the shore. Tides are caused due to the strong gravitational pull exerted by the sun and moon on the earth's surface. High tides help in navigation and fishing During spring tides, Earth, the Moon, and the Sun are aligned and the tidal effects add. (Recall that the tidal forces cause bulges on both sides.) (c) shows the relative positions for the smallest tides, called neap tides. The extremes of both high and low tides are affected A high tide occurs when ocean water covers much of the shore by rising to its highest level. When ocean water falls to its lowest level and recedes from the shore, it is referred to as a low tide. Tides are caused by the strong gravitational pull exerted by the Sun and the Moon on the Earth's surface. Formation of high and low tides

Tides are caused by the Moon's gravitational pull which generates something called tidal force. This is because the Moon is much closer to the Earth and thus has more power to pull the tides. The tidal force bulges out the Earth and its water to the faces closest and farthest from the Moon. Such bulges of water are called high tides Tides are caused by: The moon's gravitational pull to a great extent The sun's gravitational pull to some extent are the major causes for the occurrence of tides. Another factor is centrifugal force, which is the force that acts to counter balance the gravity
The Proxigean Spring Tide is a rare, unusually high tide. This very high tide occurs when the moon is both unusually close to the Earth (at its closest perigee, called the proxigee) and in the New Moon phase (when the Moon is between the Sun and the Earth).The proxigean spring tide occurs at most once every 1.5 years. Neap Tides. Neap tides are especially weak tides How Much You Know About Tides? Trivia Quiz - ProProfs Quiz

Geography complicates the tides, but many places on Earth experience just two high and two low tides every 24 hours and 50 minutes. (The extra 50 minutes is caused by the distance the moon moves. Tides are periodic rise and fall of large masses of water. They are caused by the gravitational interaction that exists between the Earth and the Moon. On the other hand, waves are caused by the winds blowing on the surface of the ocean or even lakes. This happens all the time. This is one of the important differences between tides and waves The biggest waves in our oceans are the tides. These are caused by the gravitational forces between the earth and the sun and the moon. The moon has the biggest influence because it is close. It essentially pulls up a bulge in the ocean on the side of the earth closest to it. It actually pulls up the land too, but not as much Tides. Introduction to Tides.

(4) Apogean and Perigean Tides: The nearest position of the moon with the earth is called perigee when the distance between them is 3,56,000 km. The tidal force of the moon is most powerful during this position and hence high tides are caused. Such tides, called as perigean tides, are 15 to 20 per cent higher than the normal tides 1. Tides are formed because of the interaction of the gravitational forces between the Earth, the moon, and the sun. 2.Waves are formed because of the gusting or raging force exerted by the wind on the water surface. 3.Tides are usually generated at the deep oceanic regions while waves are usually seen at shallower areas of the sea The gravitational force causes: a) Tides b) None of them c) Motion of moon d) Both a and c. >. 11th. > Physics TIDES TYPES OF TIDES: HIGH TIDE AND LOW TIDE; SPRING TIDES AND NEAP TIDES.

Choose the correct option. Question 1 This receding tide is known as an Ebb Tide. The ebb tide is a transition phase from the high tide to low tide. This causes a low tide. Again after another 1/4 th of the tidal cycle, the water starts to flood back in bringing in the high tide. This tide is known as the Flood tide. Effect of Topography on the Tides Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun, and the rotation of the Earth.. Tide tables can be used for any given locale to find the predicted times and amplitude (or tidal range). The predictions are influenced by many factors including the alignment of the Sun and Moon, the phase and amplitude of the. B. Neap tides: Lower tides. Occurring at seven day interval between spring tides and neap tides. Sun and Moon at right angle to each other forces act counter on another. Terminology related to tides: Ebb: Time between high tide and low tide, when water level is falling. Flow or flood: Time between low tide and high tide when water level is rising
on the earth's surface causes the tides. The water of the earth closer to the moon gets pulled under the influence of the moon's gravitational force and causes high tide. During the full moon and new moon days, the sun, the moon and the earth are in the same line and the tides are highest. These tides are called spring tides.

Tides are caused by small perturbations to gravity due to the sun and moon. The sun is highest in the sky once a day, and the moon is on almost the same schedule, being highest in the sky once every 24 hours and 50 minutes. So why are there two tidal cycles? The reason is that the forcing from either sun or moon peaks twice a day The rotational force causes water to pile up as the water tries to resist that force, so high tides form on this side, too. Elsewhere on the Earth, the ocean recedes, producing low tides. The gravitational attraction of the Sun also plays a small role in the formation of tides. Tides move around the Earth as bulges in the ocean
Tides can be tracked at specific locations in order to predict the height of a tide, i.e. when low and high tide will occur in the future. The Bay of Fundy in Nova Scotia, Canada has the highest tidal range of any place on the planet. The tides there range from 11 feet (3.5 m) to 53 feet (16 m) and cause erosion, creating massive cliffs These are called spring tides. When the Earth, Moon and Sun form a right angle (at 90°) the high water caused by the lunar tide coincides with the low water of the solar tide. This produces lower than average high waters and higher than average low waters which are called neap tides. They occur approximately 7 days after spring tides (Low tide will be at the sides halfway between the high tide bulges.) 5. The moon can then circle the earth several times so the rhythm of the passing of the moon and the bulging of the waters is experienced by the class. Before ten minutes are up, even ﬁrst and second graders have a feel for how the moon affects the tides. 3. Then Do Tides.
NAVIGATION . Tides. The tide is the vertical rise and fall of the sea level surface caused primarily by the change in gravitational attraction of the moon, and to a lesser extent the sun. As the earth spins on its axis the centrifugal force results in slightly deeper water near the equator opposed to shallower water at the poles A flow tide or a flood tide is a rising tide or incoming tide which results in a high tide. It is thus the time period between a low tide and a high tide (i.e., the rising time). Ebb Tide is the receding or outgoing tide. It is the period between high tide and low tide during which water flows away from the shore. Types of Tides An earthquake is caused by a sudden slip on a fault.The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.. In California there are two plates - the Pacific Plate and the.
