Step by step
Solved in 2 steps
- Answer the following questions: 1.) How does wind, evaporation and tide in fluence the distribution of salinity in the estuary? 2.) Why is it a problem to the animals lacking siphons to live in the sediment? List two problems.Starting with a drop of water in the ocean, describe a full cycle of movement of the water drop through the hydrologic cycle (the water must end up back in the ocean). Through what reservoirs does that water move? What physical forms does the water take (e.g., liquid, solid, gasIf salinity changes (increases) in a freshwater body, what influence would this have on aquatic communities and individual aquatic organisms?
