ground bounce is the term used to refer to the change in the voltage of the ground plane from 0V to some value due to inductance in the line connected to the ground...
here due to sudden change in current flowing towards the ground plane through the inductance a voltage is developed.... high frequency noise generally poses a serious problem...

Thanks for the reply. I have a few queries.
> Is this effect profound only at RF frequencies?
> How is capacitance related to it?
> How do we avoid this GROUND BOUNCE?
it is profound in circuits where a sudden change in current flowing to ground is possible... it is not necessarily profound in rf circuits....
the inductance along the line is the serious issue... sometimes the capacitance of the ground plane stores charge causing ground bounce... in this case it can be reduced by spreading the ground plane larger reducing the capacitance...
