The coastal environment, or littoral zone, is considered to extend seaward as far as _______. the coastal environment, or littoral zone, is considered to extend seaward as far as _______. the depth where storm waves can no longer move sediments.
The correct choice is that it extends until depths of around 60 m where sediments cannot move anymore. The important thing is that it certainly is not just the contact point of water and land; it goes into the sea until this point, where also enough light reaches the bottom for plants to do photosynthesis. D is wrong because breakers do not play a role in this definition, although it can vary from context to context (sea, lakes etc.).
