Answer:
Anomalous expansion
Explanation:
Anomalous expansion of water is the abnormal way water expands when exposed to low temperature.
At 4 degree Celsius , the density at the top layer is usually at the Maximum which makes the water sinks down and then the water in the lower layer rises up.
When the temperature drops below 4 degree Celsius, the water molecules at the top then freezes leaving the denser molecules at the bottom which doesn’t freeze as a result of their high density.
This way, organisms can survive in the water due to the lower layer not freezing.
Bees fly to flower to flower gathering nectar, which they make into food benefiting the bees.
Mainly to make life easier.
if one layer changes than scientists don't need to change all of their data.
it also helps keep organized.
