Any enters-the-battlefield abilities of the copied land card will trigger when Echoing Deeps enters the battlefield. Any "as [this land] enters the battlefield" or "[this land] enters the battlefield with" abilities of the chosen land card will also work.

Echoing Deeps copies exactly what was printed on the original land card, with the noted exception.

If you choose to have Echoing Deeps not copy anything, it enters the battlefield untapped.
