Global map of major lakes (in yellow and orange)
Abiotic factors and distinctive features
Salinity: Most lakes are freshwater but there are a few major exceptions to this, ie Salt Lake and Dead Sea
Movement: Relatively no movement; lakes are contained bodies of water
Temperature:
-Water can be heated or cooled through radiation at the surface and conduction to or from the air
-Shallow ponds have a temperature gradient from warmer waters at the surface to cooler waters at the bottom
-Temperature fluctuations can be very great in these systems
Light:
-Small ponds may experience shading by surrounding trees
-Cloud cover may affect light availability in all systems, regardless of size
