How does the density of ice affect aquatic life in winter?
Ice floats on water, insulating it and allowing life to thrive beneath.
Ice sinks, which increases pressure on aquatic life.
Ice reflects sunlight, preventing photosynthesis in aquatic plants.
Ice decreases the oxygen levels in the water.
What unique property of water allows ice to float?
Water expands when it freezes, making ice less dense than liquid water.
Ice has a lower boiling point than liquid water.
Ice is made up of different molecules than liquid water.
Water has a pH level that decreases when it freezes.
What impact does melting ice have on aquatic ecosystems?
It causes a sudden increase in water levels that can flood habitats.
It decreases the temperature of the surrounding water immediately.
It introduces freshwater that can alter salinity and affect species.
It removes important nutrients from the water.
