Tides are caused by the gravitational attraction of the moon (and other astronomical bodies to a lesser extent), and tsunamis are caused by earthquakes. Tides are very predictable, tsunamis are very unpredictable.

What are the two different ways to classify tides?
in and out the tide is out the tide is in
What is the difference between a storm surge or a tidal bore?
A storm surge is a mass of water that is pushed on land by the winds of a large, powerful storm such as a hurricane. A tidal bore is a wave that travels up a river, bay or inlet produce by an incoming high tide.
What are some signs of red tide?
Red tide is caused by Algal blooms- During which, algae becomes so numerous and it may deplete oxygen and emit toxins into the air. different species in the water causes a discoloration.
What is a big wave called?
The largest waves are called tsunamis. They were once called tidal waves, but scientists learned that most of them are caused by underwater earthquakes instead of by tides, so we now use the Japanese name tsunami. A tsunami can be hundreds of feet high!
What is a large wave created by some earthquakes?
a tsunami
What was the cause of a tsunami?
A strong incoming tide at the mouth of some rivers produces a bore (a wave) that moves up the river against the current.
Is a Tsunami a type of Avalanche?
Tsunami are sometimes referred to as tidal waves or water avalanches. In recent years, this term has fallen out of favor, especially in the scientific community, because tsunami actually have nothing to do with tides. The once-popular term derives from their most common appearance, which is that of an extraordinarily high tide bore.
Is a tidal wave the same thing as a typhoon?
No. The term tidal wave may refer either to a tidal bore or a tsunami, both of which are entirely different from typhoons. A typhoon is a hurricane that occurs in the western Pacific Ocean; a storm that produces large waves, torrential rain, and very powerful winds. A tsunami is a long-ocean wave or series of waves triggered by some disturbance on the seafloor, usually an earthquake. A tidal bore is a surge of water that occurs when a rising tide is funneled into an inlet or estuary.
Did the recent tsunami hit New Zealannd?
Yep. but it was only about a metre and it was lie tide so did nothing other than create a strong current in Cape. if it had been high tide it might have been a different story!
What is a wave that forms when a rising tide enters a shallow narrow river from a wide area of the sea?
A Tidal Bore is a wave that forms when a rising tide enters a shallow, narrow river from a wide area of the sea.
When next river dee bore at saltney ferry?
From Saltney Ferry its tomorrow 10.55am at 8.6m tide , or Sunday the 8th 19.45pm at 8.9m tide.
How is a tidal bore created?
A tidal bore results when the conformation of a bay funnels the incoming tide into a fairly narrow river channel. The effect is a result of the flood tide's duration's being shortened by the land shape so that it acts very suddenly.
Before a tsunami the ocean appears that it is at low tide?
True... The Tsunami 'draws in' water - which makes the local ocean appear to vanish... before the wave hits the shoreline
Why does low tide occur after the earthquake and before the tsunami?
It isn't low tide, but part of the wave. Each wave in a tsunami has two parts: a crest of high water and a trough of low water. In many cases the trough comes first, resulting in the water receding.
How you know when a tsunami is coming?
the tide will go out unnusally far causing the water to go very shallow
Bulge that takes place on parts of earth facing or opposite the moon?
high tide
Are a seismic sea wave and a tsunami the same thing?
The term tidal wave is often used to mean a tsunami. However, the term "tidal wave" has fallen out of favor because tsunamis have nothing to do with tides. The term tidal wave may also refer to a tidal bore, which is a wave that forms in some locations when the tide is rising.
