What is development ? explain the changing concept of development

Development means “improvement in country’s economic and social conditions”. More specially, it refers to improvements in way of managing an area’s natural and human resources. In order to create wealth and improve people’s lives.

Dudley Seers while elaborating on the meaning of development suggests that while there can be value judgements on what is development and what is not, it should be a universally acceptable aim of development to make for conditions that lead to a realisation of the potentials of human personality.

Explanation:

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.
