Answer 1

At what points during the year are fish—which need a large amount of dissolved oxygen—most likely to be evenly distributed throughout the water of a lake that freezes over in winter?

Spring and fall when warm and cold water mixes <--- my choice but not 100% sure
Fall and winter when the water is warmer
Summer and winter when warm water settles on the bottom
Spring and summer when the cold water settles on top

Answer 13

During summer, temperature is higher on the surface water, whereas in lower layer temperature is low. During winter, water is at freezing temperature on the surface, whereas in the lower layer temperature is about 4 degrees. The surface water is cooled during autumn, and warmed in spring. This results in a free mixing of water in the whole water body. During spring and autumn due to turnover of water oxygen and nutrients are redistributed.
