Fill in the blank. A ____ is when deep many lakes undergo a semiannual mixing of their waters during the transitions seasons. (spring/ fall)
A. thermocline
B. turnover
B. turnover
True or False?
Turnover mixes oxygenated water from the surface with nutrient-rich water from the bottom
TRUE
Fill in the blank. ______ is a temperature boundary mechanism that separates the warm upper layer from the cold deeper water
A. wetlands
B. estuary
C. thermocline
C. thermocline
True or False? in the spring, oxygen goes to the bottom while nutrients go to the top
TRUE
True of False. in the fall, water cools rapidly sinks beneath underlying layers… then remixes until the surface water begins to freeze
TRUE
True or False?
Thermocline takes place in the winter. its when the warm water is separated by the cold bottom. there’s a vertical zone of abrupt temp change
FALSE. Thermocline takes place in the SUMMER. its when the warm water is separated by the cold bottom. there’s a vertical zone of abrupt temp change
