Lookup relation is more loosely coupled and child's existence doesn't depend on parent. In look up relation child record has complete separate permission and record visibility. For example country object which is look up on customer's address doesn't need to drive it's permission by account object as country object can be related to multiple other object where address detail is available. Country object which holds all country data is independent of any other oobject but let's say you add provinces as object and then it makes sense to have relation between province and country to be master detail because if you delete country it doesn't make sense to keep its provinces. Make sense?
