A. the distribution of sand on an ocean floor
1. The science of classifying living things is called taxonomy. Linnaeus introduced the classification system that forms the basis of modern classification. Taxa in the Linnaean system include the kingdom, phylum, class, order, family, genus, and species. ... The domain is a broader taxon than the kingdom.
2. Don't travel by air if you can avoid it because air travel uses up large amounts of fossil fuels and creates greenhouse gases. Dispose of any rubbish responsibly - it can be hazardous to wildlife. Use public transport, cycle or walk instead of using a car. Use facilities and trips run by local people whenever possible.

The quality of water drawn from an aquifer differs in quality from surface freshwater because the surface water contains a lot of contaminant. Even when a ground water contains contaminants in it, it is filtered by the rocks in underground.
<u>Explanation:</u>
The water that are in river, ocean or any other water from surface level is known to be a surface water. This water is subjected to the exposure of many contaminants as they are directly on the earth's surface. These are known as "soft water" and they usually contain more minerals. The surface water can be contaminated by waste of humans, animals, industry wastes, etc. Hence they have low quality.
A Deep well drilling must be done in order to take water form the Large aquifers that are present Groundwater. The ground water also contains contaminant. But, the quality of these water is high since the rocks and soil found underground filters and removes the contaminates that are present in an underground water.
