Which of the following aquatic environments would not freeze in winter?
a.
lake
b.

c.
salt marsh
d.
stream

The right answer is salt marsh.

the oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf, but operationally is often referred to as beginning where the water depths drop to below 100 meters (328 feet), seaward from the coast to the open ocean.
