What is a tide answer?
Tides are very long-period waves that move through the ocean in response to the forces exerted by the moon and sun. Tides originate in the ocean and progress toward the coastlines where they appear as the regular rise and fall of the sea surface.
What is tide class6?
Tides are channels of water moving in a particular direction in the oceans. Alternate rise and fall of water on the ocean surface is called tide. Tides are periodic movements of ocean water due to the Moon and Sun’s gravity.
What is a basic definition of a tide?

What is tide Ncert?
The periodical rise and fall of the sea level, once or twice a day, mainly due to the attraction of the sun and the moon, is called a tide.
What is spring tide Class 7?
Spring Tides
During the full moon and new moon days, the sun, the moon and the earth are in same line and the tides are highest. These tides are called spring tides.
What are tides and waves?
Definition. Tides are the rise and fall of ocean water caused by the gravitational pull of the sun and moon. Waves are formed because of the winds blowing over the surface of the ocean.
What is tide class 5th?
Tides can be defined as the alternate rise and fall of the ocean water. It is caused by the combined effects of : The gravitational force exerted on Earth by the Sun. The gravitational force exerted on Earth by the Moon. Rotation of the Earth.
What are tides ks2?
Tides are the rise and fall of the levels of the ocean. They are caused by the gravitational pull of the Sun and Moon as well as the rotation of the Earth. Cycles of a Tide. Tides cycle as the Moon rotates around the Earth and as the position of the Sun changes.
How are tides formed Class 7?
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.
What is a tide quizlet?
A tide is the periodic rise and fall of water level in a large body of water.High tide is a water level higher than the average sea level. Low tides is a water level lower than the average sea level.
What is a sentence for tide?
Tide sentence example. With the rise and fall of the tide the discharge pipes are flushed at the bottom. He probably floated out on the tide . In the sense of “flowing water,” the word is applied to the inflow of the tide , as opposed to “ebb.”
What do tides do?
Tides affect other aspects of oceanic life, including the reproductive activities of fish and ocean plants. Floating plants and animals ride the tidal currents between the breeding areas and deeper waters. The tides help remove pollutants and circulate nutrients ocean plants and animals need to survive.
What is a wave Class 7?
Ans. Waves are the rise and fall of the water on the surface of the ocean. Waves are formed when winds scrape across the ocean surface. The stronger the wind blows, the bigger the wave becomes. During the storm, the winds blow at very high speed and therefore huge waves are formed.
What are tides Class 9?
Answer: Tides are the rise and fall of sea water due to gravitational forces of the sun and the moon. Tides are mainly caused by the centrifugal and centripetal forces of the earth and the moon.
What is tide and its type?
TIDESTypes of tides
High tide: when the sea water reaches its greatest height within the tide cycle. They are shown in blue on the tide tables. Low tide: when the sea water reaches its lowest height within the tide cycle. They are shown in red on the tide tables.
What does spring tide and neap tide Class 7 mean?
Rather, the term is derived from the concept of the tide “springing forth.” Spring tides occur twice each lunar month all year long without regard to the season. Neap tides, which also occur twice a month, happen when the sun and moon are at right angles to each other.
What is high tide and low tide Class 7?
High Tide: This occurs when water covers much of the shore by rising to its highest level. Low Tide: There is a low tide when water falls to its lowest level and recedes from the shore. Tides are caused by the strong gravitational pull exerted by the sun and the moon on the earth’s surface.
What is a terrarium class 7?
Answer: A terrarium is an artificial enclosure used for keeping small house plants. Our earth is like a terrarium.
What causes a tide?
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.
What a wave is?
A wave is a disturbance in a medium that carries energy without a net movement of particles. It may take the form of elastic deformation, a variation of pressure, electric or magnetic intensity, electric potential, or temperature.
