Answer:
Some similarities: they both contain water: ocean in a liquid form and atmosphere as water vapor and oxygen, although oceans have relatively little oxygen (but enough for the fish to catch).
Major difference is that the main substance in the atmosphere is various gasses, while the main substance in the ocean is water in liquid form.

Answer:
Groundwater protection must be a high priority in zones where contamination can easily enter the aquifer and affect a spring or pumping well used for the drinking water supply of a large population.
Explanation:
Groundwater protection has been addressed in most countries by issuance of different rules and regulations at national or local level that aim at preventing aquifer contamination. In this sense, laws have been issued to regulate the use and manufacture of toxic products, and set measures to manage the waste produced by industrial activities, and to properly place and maintain waste disposal and storage facilities (landfills, injection wells, storage tanks). Maximum allowable concentrations for some pollutants have been established, mainly in developed countries, to preserve a good quality of the groundwater exploited for drinking water supply. In addition, well-head protection areas and groundwater zone protection areas have also been defined in some developed countries to prevent pollution of drinking water sources.
The process of natural selection can lead to speciation, where a species gives rise to a new and distinctly different species.
Natural selection is defined as the differential survival and reproduction of individuals due to differences in phenotype which is a major mechanism of evolution, a change in the genetic properties of populations over generations.
Natural selection is described as the process through which populations of living organisms adapt and change where individuals in a population are naturally variable, meaning they all differ in some way is that some individuals have traits better adapted to the environment than others.
Thus, the process of natural selection can lead to speciation, where a species gives rise to a new and distinctly different species.
