What is a Pothole or Kettle lake?
Formed when ice from a glacial melt is left behind, freezing again before thawing, creating small but deep lakes

Created when debris (moraine) deposited by a glacier blocks a river or stream
What is a scour lake?
forms when a buried block of glacial ice melts, leaving behind a depression that fills with water to create a lake

Formed in bowl-shaped depressions (cirques) at the head of a glacier on a mountain
What is a graben lake?
A lake formed where a block of continental crust has slipped
What is an oxbow lake?
forms when a meandering river or stream changes course, leaving behind a curved or crescent-shaped body of water
What is a karst lake?
formed when carbonate’s are dissolved within water, creating a sinkhole
What is a caldera lake?
crater lakes are formed within volcanic craters or calderas as a result of volcanic activity and subsequent accumulation of water
What is the dissolved gas budget in aquatic ecosystems?

What is the compensation point?
production matched by respiration
