I think not sure, we are using grounding if need to protect electrical circuits by connecting all passive and active elements to commen point inside devices, but earthing is used normally wherever electro-static currents resulted due to for example lightening such as GSM,MW towers and connected directly to the earth.

Grounding is used to protect the current carrying elements like (lighting arresters) like so, here we protect by connecting phase to ground. Earthing is used to protect non-current carrying elements phase to earth.

Earthingis the main source to protect thesystem which consists of variousdevices by connecting to the ground, whereas grounding is the process of connecting all the devices to a common point which is the earthing point.

Actually current is nothing its simply flow of charges.earthing is a wire which is common to all the points in a circuit used to complete the circuit, it is compulsory .while grounding is used to pass leakage of charges to the ground ,it is used for safety measure but not compulsory.

Grounding and Earthing are the same.  Grounding is US terminology while Earthing is British terminology.

Earthing is connecting the neutral point in 3 phase circuits to ground.
Grounding is connecting an electrical equipment  individually to ground.

Earthing is done by grounding a neutral of three phase system.
Grounding is used for protection purpose for current carrying devices.

grounding means connecting the live part (it means the part which carries current under normal condition)to the earth for example neutral of power transformer & earthing means connecting the dead part (it means the part which does not carries current under normal condition) to the earth for example electrical iron etc.

Every one must have heard of PG & PE in the same system. PG stands for Potential Ground, while PE for protective earth. Potential ground means the net effect of the potential at the point is zero (usually Neutral or return point) usually for protection of equipments. While PE is for protection of operator (or Human). Usually PE & PG are connected atleast at one point to avoid any floating potential.

Grounding act as neutral...........
but neutral can't act as ground.

The term "Earthing means that the circuit is physically connected to the ground, but incase of "Grounding" the circuit is not physically connected to ground, but its potential is zero, with respect to other point,which is also known as "Virtual Grounding."

Earthing is equipments, cables which is connected to system earth for permanent purpose, for example - panel body earthing, cable sheath earthing at termination, Transformer body earthing, neutral earthing, etc...-- Means connecting component to the ground potential which is mean to be remain at ground potential at normal working condition.

Grounding means - connecting part of equipement to ground/ earth for ensuring it is at zero potential and safe to work on. Means, components which suppose to have voltage for its normal working condition, but for maintenance work on it , it is connected to earth is callled "grounding"

This is really most confusing question asked by someone?...... Actually there is no any differences between earthing and grounding... you may say this is language difference as AMERICAN uses=GROUNDING, and BRITISH uses= EARTHING,

But as this question(inspired from differences bet neutral and grounding ) becomes very famous to confuse students, few writers starts differentiating it as........EARTHING: which is connected to dead part all times.

GROUNDING: intentionally connects when needs something to discharge like after C.B opens, we need to ground transmission line for a while so that all charging current gets discharge.

BUT,Again I insist there is no difference at all except language......

Continuing........ As You can see in any book, they write Grounding/Earthing(Grounding or Earthing), they never write Grounding and Earthing

When we take out the neutral for a three phase unbalanced connection and send it to ground, it is called grounding. Grounding is done to to balance unbalanced load.

While earthing is used between the equipment and earth pit so as to avoid electrical shock and equipment damage.

Earthing is to protect the circuit elements whenever high voltage is passed by thunders or by any other source.

Grounding is the common point in the circuit to maintain the voltage levels.

Earthing actually means to,if there is an excessive voltage(not current) flowing in a power system,for the protection purpose it is connected to the earth with a help of rod,or by some other metals,so that the voltages flows to ground....

Neutral point or Grounding means,excessive or fault current flowing in the power system is also connected to the earth through rods,but which then act as a return path and gives back the current to the system itself..(i.e) the system cannot perform when it is in open loop,this neutral forms a closed loop...
