What is tides and waves?
Tides are the rise and fall of water levels in the ocean due to gravitational pulls. Waves are a series of crests and troughs in the water that are formed due to the impact of wind or other forces.
What is tide in sea?
The alternating advance and retreat of seawater along a coastline is called a tide. High tide is when water advances to its furthest extent onto the shoreline. Low tide is when it recedes to its furthest extent. Some freshwater rivers and lakes can have tides, too.

What is a tide example?
The definition of tide is the cycle of rising and falling of the surface of bodies of water caused by the attraction of the moon and the sun. An example of the tide is when the ocean’s water is at its highest point on the beach.
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 are tides Class 11?
What are tides? Answer: 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. Tides vary in their frequency, direction and movement from place to place and also from time to time.
Why are there tides?
How do tides work?
High tides and low tides are caused by the moon. 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.
What are tides Geography 11?
How tides are caused?
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. When the lowest point, or the trough, reaches a coast, the coast experiences a low tide.
Why are tides important to life on Earth?
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.
