Which statement BEST describes an effect of
the low density of frozen water in a lake?
A. When water
freezes, in contracts, decreasing the water level in a lake.
B. Water in a lake
freezes from the bottom up,
killing most aquatic organisms.
C. When water in a
lake freezes, it floats, providing insulation for organisms below.*** Remember we discussed how lakes do NOT freeze from the bottom up. If they did most of the marine life in that lake/pond would die off every year!!!
D. Water removes
thermal energy from the land around a lake, causing the lake to freeze.
Before we took our open notes quiz I had you watch the following crash course and instructed you to pull out 5 terms he discussed, jot them down, and then write a statement about each term and how it applies to our study of water.
We then took our open notes quiz!! Tomorrow = Daily Question Quiz!!!!
