Lake stratification, a Common card

The card carries these facts from its Wikipedia article.

• Typically stratified lakes show three distinct layers: the epilimnion, comprising the top warm layer, the thermocline, the middle layer, whose depth may change throughout the day, and the colder hypolimnion, extending to the floor of the lake.
• Every lake has a set mixing regime that is influenced by lake morphometry and environmental conditions.
• However, changes to human influences in the form of land use change, increases in temperature, and changes to weather patterns have been shown to alter the timing and intensity of stratification in lakes around the globe.
