Trespass vs Nuisance: Kya Fark Hai?

Yaar samajh nahi aaya, main toh 3 baar Bare Act padkar bhi confused hoon. Trespass aur Nuisance dono hi Tort of Interference with a person's land hai, lekin kya fark hai? Mere paas lagta hai ki Nuisance ek type of Trespass hai, lekin book mein likhaa hai ki Nuisance ek alag hi tort hai. Kya ye sahi hai? Aise cases jaise Prie v/s Greenock Corp (2011) mein bhi confusion aayi hai. Judge ne kaha ki Nuisance ek type of Interference hai, par kya ye Trespass hi nahi hai? Please help, main confuse hoon. Koi example ya reference de sakta hai kya jisse meri confusion door ho jaye?
