Why Earth is Bulged at the Equator

Why is Earth bulged at equator ?
Please don't explain in terms of centrifugal force

How about Newton's First Law? Objects in motion tend to keep moving in a straight line, so the part of the Earth that is at the equator has a tendency to keep moving straight, rather than in a circle, causing an outward bulge.

That explanation has been forbidden by the OP. I don't know, how to answer the question, when I'm forbidden to answer the way it is. So I don't answer at all!

The explanation given above does not mention centrifugal force -- it correctly describes the effect in terms of inertia!

I'm confused here. A is the cause of B, and you want us to explain B without referring to A...ummm...so you want us to make up an explanation? Something involving supernatural beings?

That's the same thing; he merely avoided the term that the OP didn't want to hear.
However, perhaps the OP simply doesn't want to hear about fictive centrifugal force. In that case all replies are conform.

as the distance from axis to the equator is more, The particles require more centripetal force which is to be provided by gravitational force . more gravitational force means
more particles must accumulate at equator.

I THINK THIS IS THE REASON.

I'm afraid it isn't. The gravitational force is actually less at the equator than it is at the poles, and the gravitational force does not act in the direction of the equator.

Also, gravity is not the only force acting on the particles. Have you tried drawing a force diagram?

Why don't you want an explanation in terms of Centrifugal force?

Why a nuclear plant produces energy ?
Please don't explain it in terms of E=mc2
