Water contributes to the fitness of the environment to support life by acting as a Solvent for molecules to interact Moderate Earth's climate.
Water contributes to the fitness of the environment to support life in several ways :
- Life on Earth began in water and evolved there for 3 billion years before colonizing the land.
- Even terrestrial organisms are tied to water.
- Most cells are surrounded by water.
- Cells are about 70–95% water.
- Water is a reactant in many of the chemical reactions of life.
- Water is the only common substance that exists in the natural world in all three physical states of matter: solid ice, liquid water, and water vapour.
- Water stabilizes air temperatures by absorbing heat from warmer air and releasing heat to cooler air.
- Water can absorb or release relatively large amounts of heat with only a slight change in its own temperature.
- Water’s high heat of vaporization moderates climate.
- Much of the sun’s heat absorbed by tropical oceans is used for evaporation of surface water.
- Water is unusual because it is less dense as a solid than as a cold liquid.
- Most materials contract as they solidify, but water expands.
- At temperatures above 4°C, water behaves like other liquids, expanding as it warms and contracting as it cools.
- Water begins to freeze when its molecules are no longer moving vigorously enough to break their hydrogen bonds.
- When water reaches 0°C, water becomes locked into a crystalline lattice, with each water molecule bonded to a maximum of four partners.

Answer: The skin lotion is a colloidal mixture of water and various oils.
Explanation:
Mixture: Blend of of two or more components which are chemically unreactive to give any product.
Mixture are defined as of three types:
Solutions : Mixture in which one component is completely distributed in an other component resulting in clear mixture. They cannot be separated into its components on standing or by filtration.
Suspensions: Mixture in which one component is not completely or uniformly distributed in another component.They separate out into layers when kept undisturbed.
Colloids: Mixture in which one component is uniformly distributed in another component but the mixture formed is not clear. The color of mixture appears turbid or cloudy. They cannot get separated by filtration. They also cannot get separated into its components when left standing.
A skin lotion is a fine mixture of water and oils. it is a cloudy mixture and cannot be separated with help of filtration. Also its components also not separates out on standing. All these properties shown by skin lotion is of colloidal mixture.
