Why did Gandhi suspended non cooperation movement .

Gandhiji called off the movement in February 1922 in the wake of the Chauri Chaura incident.

In Chauri Chaura, Uttar Pradesh, a violent mob set fire to a police station killing 22 policemen during a clash between the police and protesters of the movement.

Gandhiji called off the movement saying people were not ready for revolt against the government through ahimsa. A lot of leaders like Motilal Nehru and C R Das were against the suspension of the movement only due to sporadic incidents of violence.

giant impact theory - the moon was formed from the collision between earth and another mars-sized body.

colliding planetesimals hypothesis - the moon was formed from the same cloud of material as earth.

capture hypothesis - the moon was locked into orbit by earths gravity as it was passing by it.

accretion hypothesis - the moon was formed from collisions and combining of planetesimals.

i think this is right, if not and you know better let me know.
