Document Summary
Sea smaller than ocean and usually associated with landmass. Can also be large inland salty body of water. Carbonation forms carbonic acid resulting in lower ph. Collects at surface and can dissolve into lower layers. Coast: inland from high tide to first landform change. G effect on side of earth facing the moon or sun greater than far side. Spring: when sun and moon on same side of earth and result in greatest tidal range. Opposition: moon and sun opposite sides of earth cause separate tidal bulges. Neap: g offset and counteract with each other producing less tidal range. Friction btwn moving air and ocean surface make undulations. Breaker: point reached when height exceeds vertical stability. Waves of translation: e and water move toward shore. E focused around headlands and dissipates at coves. Longshore current/littoral current: depends on wind direction and resultant wave direction. Littoral drift: combined actions of longshore current and beach drift.
