I guess I'll be the first to post here! Let's start on the easier side:
1. In a dimictic lake, during what season is the hypolimnion warmer than the epilimnion?
2. During which season(s) does lake overturning occur in dimictic lakes, and why?

1. The Hyolimnion is warmer than the epilimnion in the winter
2. Lake overturning ocurs in dimictic lakes during the fall and spring because the surface water cools, which causes it to be more dense so it sinks.
I'll start with the next questions now.
1. What are the 4 processes that occur to help streams reach Dynamic Equilibrium.
2. Which of these processes do humans try to interrupt and "fix"?

not sure if this is correct but i tried-
1. The four fluvial processes that may help streams reach dynamic equilibrium (in which streams quickly respond/change to an equilibrium state) are degradation, aggradation, widening, and plan-form change; a state of dynamic equilibrium indicates that these processes are mature and developed.
Degradation refers to the downcutting and lowering of the stream bed; in contrast, aggradation is the raising of the bed elevation through sediment accumulation. After the initial channel processes, stream bank erosional processes may occur in channel widening. Similarly, planform change is also related to stream channel shape (slope).
2. While planform change occurs naturally, it often occurs through human interference in attempts to straighten river channels.

Yes, that's correct. Your turn!

oh yay cool thanks!
1. The Kansas River flows into the Missouri River and therefore has, in comparison, a smaller drainage area. Would you expect the effect of climatic conditions to be greater on the Kansas River or Missouri River? Which River would have a wider range in quality?
2. Kansas' water supply mainly comes from underground wells and has a hardness average of 299 ppm. Would this water be considered hard? If so, what minerals would you expect to be present?
