Approximately how many gallons of water are used per year in a typical home? 1 million gallons 500,000 gallons 150,000 gallons 1

Advocard [28]

146 gallons of water

<h2>Further explanation </h2>

The human need for water (for drinking) is 8 glasses a day or about 2 liters. 1 gallon usually contains 19-20 liters. One house usually consists of 4 people <em>(father, mother, brother, sister). </em>

If one person consumes 2 liters of water, then one house will consume about 8 liters a day.

Which will take up 2 gallons in 5 days.

1 Year = 365 days

365 days : 5 days <em>(2 gallons)</em> = 73 <em>(gallon water refill frequency) </em>

73 x 2 = 146

So, within 1 year the level of gallon water consumption in an ordinary house consumes 146 gallons of water.

That is the calculation of the use of gallons for consumption, <em>not for bathing, washing, pooping, urinating, etc. </em>

In two or three well-developed paragraphs, explain how pollution can come from both natural sources and from human activities. P

spayn [35]

Pollution can come from both natural sources and human activities depending on the type of pollutant.

<h3>What is pollution?</h3>

It is the release of substances into the environment to the extent that the well-being of plants, animals, and humans starts getting affected.

Substances that are released into the environment to the extent that they start affecting the organisms in the environment negatively are known as pollutants.

Pollutants can come from natural sources or as a result of human activities.

For example pollutants such as oxides of sulfur, methane, carbon dioxide, etc. can come from natural processes such as volcanic eruptions, activities of microbes, etc.

Pollutants such as oxides of carbon and sulfur can also be generated as a result of human activities such as the burning of coal, technological inventions, etc.
