IN Wikipedia: "What are the 7 worlds in Hinduism? In the Puranas and in the Atharvaveda, there are 14 worlds, seven higher ones (Vyahrtis) and seven lower ones (Pātālas), viz. bhu, bhuvas, svar, mahas, janas, tapas, and satya above and atala, vitala, sutala, rasātala, talātala, mahātala, pātāla and naraka at the bottom."
"A kalpa is followed by a pralaya (partial dissolution, a.k.a. night of Brahma) of equal length, when Brahma and the universe are in an unmanifested state. Each kalpa has 15 manvantara-sandhyas (junctures of great flooding) and 14 manvantaras"
