No apparently... Terra Cave is exclusive to Emerald only~ You can, however, trade the Groudon from Terra Cave from Emerald and the traded Groudon might say something about "apparently met at Lv. 70 Terra Cave".
It depends. Ask the scientist in the Weather Forecast Lab. He is on the second floor.
Beat the Elite 4, then go to the Weather Institute and the man will tell you where strange weather is occuring. Go to that route and you will see a new cave entrance or dive spot.
No.You have to trade from Pokemon Ruby or Pokemon Sapphire, except if you have Pokemon Emerald.Then after you beat the Elite 4, talk to the Weather Institute Owner,He will tell you a route,Head to the route and there will be a cave,It would be either Terra Cave or Marine Cave,Inside if Terra Cave,There will be Groudon,If Marine Cave,There will be Kyogre.
What cave?
If there is a Drought in a Route on Pokemon Emerald it means Terra Cave has appeared in that Route. Terra Cave is a randomly spawning cave that contains the legendary Pokemon Groudon. Terra Cave only appears after defeating the Elite Four.
You can get a Groudon on Pokemon Emerald in Terra Cave.
