Is dependence is on the sea a characteristic of athens, sparta, or both?

I would say Athens was much more dependent on the sea.    Athens had a much greater dependence on the sea for their military capabilities than Sparta.  Athens relied on their navy for defense whereas Sparta relied on ground forces. Sparta was an agricultural society where Athens relied on trade.

The Constitution nowhere contains an express injunction to preserve the boundaries of the three broad powers it grants, nor does it expressly enjoin maintenance of a system of checks and balances. Yet, it does grant to three separate branches the powers to legislate, to execute, and to adjudicate, and it provides throughout the document the means by which each of the branches could resist the blandishments and incursions of the others. The Framers drew up our basic charter against a background rich in the theorizing of scholars and statesmen regarding the proper ordering in a system of government of conferring sufficient power to govern while withholding the ability to abridge the liberties of the governed.
