4. reaching the maximum water level, or high tide.
5. when the water gradually moves away from the coast.
7. is the ice part of the hydrosphere
8. Seawater density varies with temperature, salinity, and depth. High temperature produces low density, and high salinity produces high density.
9. is the difference in elevation between high and low tide.
10. of seawater is a measure of the concentration of dissolved salts, which are mostly sodium chloride but also include salts containing magnesium, sulfur, calcium, and potassium.
11. are essentially “bulges” in the sea surface in some places that are compensated by lower areas or “sinks” in the surface elsewhere.
