A tide generating force has two dynamic properties. One of them is a property as a vector with magnitude and direction, the other is a periodicity of force acting with a cycle of about 12 hours. When an object receives a periodical external force, the object certainly vibrates. This vibration is referred to as forced oscillation in physics. So, from the perspective of physics, it is very rational to consider that tides are the forced oscillation movements of the ocean caused by the periodicity of tide generating force. Applying the theory of forced oscillation to the tidal phenomena, the tides of the ocean can be classified into three types of movements according to the depth of the sea. When the depth is shallower than 22,000m, the tidal response of the ocean must be "out of phase" with the tidal force, and when deeper than 22,000m, it must be "in phase". Further, when the depth will be equal to 22,000m, the tidal response of the ocean must be "resonance". Therefore, the amplitude of tide becomes infinite in scale. In this paper, this kind of extremely huge scale of tide, predicted theoretically, is called "tide burst". Some scientific meanings of the concept of tide burst, especially in relation to Earth science and astronomy, will be discussed in detail.
