Waves :-
Different types are tides are know as waves .
Waves can occur anytime .
Ex- u blow air over hot milk or tea,while drinking,ripples are gathered on the milk or the tea .In the same way because of force of the wind ,water appears to be moving .The sea water get pushed by the wind ripples are generated on the water surface .These are called waves .
Movement of wind occurs are called waves .
Structure of the waves:-
the sea water get pushed up and down because of the wind the raised up portion of wave is called crest and the depressed one is called and the depressed one is called trough. if a strong wind is blowing in One Direction large waves are generated.
the vertical distance between a crest and the following trough is called the amplitude of the wave where is the distance between two successive crests or troughs is called wave length . the wave length,it's amplitude and its velocity depend upon on the velocity of the Wind.
velocity of waves:-
if which stand at the courts we feel the waves are coming towards the cost if a floating object is thrown at a distance in the sea we find the object moving up and down at the same place it does not come to the coast it means the water forming the wave also does not come to the cost remember that the water in the wave does not move what moves is the energy.
the main reason of wave generation is wind but at times due to earthquake or volcanic eruptions occurring below the floor of the sea waves generated such waves assume a great height in the shallow waters near the coast this waves are very destructive they cause large use loss of property and life . this waves are called tsunamis in 2004 Tsunami waves generated because of the earthquake that took place near Sumrata is land of Indonesia. baby was the east coast of India as well as of Sri Lanka.
the way cause erosion along the headlands and create beaches in the protected locations in the bays.
ALWAYS REMEMBER:-
IF EARTHQUAKE OCCURS IN THE OCEAN THE COASTAL AREAS FACE HOROSCOPE TSUNAMI IN SUCH CASES IT IS BETTER TO GO AWAY FROM THE COAST OR TOWARDS HIGHER ALTITUDE THIS WAY LAWS OF LIFE CAN BE AVOIDED.
