DO VOLCANIC EXPLOSIONS AND EARTHQUAKES OCCUR INSIDE OCEANS ALSO?
The waves that we see in the seas and oceans are mainly caused by air currents. The size of the sea waves depends on the speed of the wind and for how long the wind has been blowing. Tide and ebb are caused by the pull of the moon (and to some extent, the pull of the sun) on the water. Mighty waves like tsunamis are caused by earthquakes below the water surface in seas and oceans. WHAT IS VISCOSITY? Viscosity is a property seen in fluids that offers resistance to a body moving through them. It is equivalent to friction. Whenever a body falls through a viscous fluid, it reaches a terminal velocity or uniform speed due to the viscous force that balances gravity. WHY IS IT THAT WE CAN WALK MORE EASILY ON WET SAND THAN ON DRY SAND? Have you not come across the Newton’s Laws Of Motion? Everyone continues in a state of rest or uniform motional, unless compelled to do otherwise by an impressed (external) force. Walking is possible because the ground on which we walk offers some resistance. As
