This property allows fish living in lakes and ponds to survive the winter. The ice that freezes on the surface insulates the water below so it stays warmer! In general, it is extremely unusual for the solid phase of a substance to be less dense than its liquid phase, but lucky for aquatic life it is!

Global warming and the greenhouse effect are related because they are both caused by pollution and rising global temperatures by human activity.
Answer: Genetic Change
Explanation:
Mutations contribute to genetic variation by causing new traits to emerge. Mutations happen when there is a change in the DNA of a creature developing in utero. These random changes in creatures are common, although most mutations end up being lethal or inhibiting to the organism. In rare cases, this mutation can prove benificial or helpful, and if the organism reproduces and the trait is passed along, it could become a new branch of genetic variation within the species.
