State three reasons why an airborne pollutant might be deposited close to its source

Answers

Answer:

No wind

Rain

I only came up with 2 I couldnt think of a third one

If an airborne pollutant is brought to the ground by rain or snow, it will be deposited closer to its source. This is due to the fact that the chemicals must be discharged nearby the source or captured in a cloud that would then transfer them.

What are pollutants?

Pollutants are substances which causes pollution to the atmosphere or hydrosphere. There are many types of airborne pollutants such as gaseous products from burning of fossil fuels.

Oxides of nitrogen and sulfur and some hydrocarbons  are the main airborne pollutants. They can be easily condensed because of the atmospheric humidity.

The deposition of these pollutants also depends on the wind, temperature and  diffusion rate of these gases. If the diffusion rate is less for the gas and the temperature is lower, they will deposit at the sources.

I'D REALLY APPRECIATE IT! ALSO MARKING BRAINLIEST!Write a 1 to 2 paragraph evaluation of the essay titled "Take Another Look at Electric Cars". Use your graphic organizer and include textual evidence.Heres the essay:Take Another Look at Electric CarsThe average automobile driver pays $2,000 annually for gasoline. That $2,000 of gas is contributing to both the United States dependency on foreign countries and environmental pollution. Electric cars are beneficial for their owners and for the environment. Anybody who is buying a new car should consider purchasing an electric car.Electric vehicles have a reputation as being expensive, but that has changed in the past few years. Purchase prices have been dropping and a federal tax credit lowers their actual cost even more. The average cost of a brand new gas automobile is approximately $31,500. Most new electric cars are priced between $30,000 and $40,000. That is a higher initial cost, but when you factor in the $7,500 federal tax credit (and possible additional state tax credits, depending on where you live), the price becomes comparable to that of a gasoline car. The annual costs associated with owning a car are much lower with an electric car. The average driver pays about $2,000 a year for gas. The average cost of electricity for a year of driving is $500. That will save $1,500 a year in fuel. Additionally, a more modern and streamlined engine will save drivers in other maintenance fees. One government study estimated that electric-car drivers will save over 40 percent in annual maintenance fees.One of the biggest arguments against electric cars has been their limited range. Electric cars do have a shorter range, but that range is plenty for most drivers. The majority of American drivers travel less than 35 miles a day, and the average electric car has a range of about 100 miles on a full charge. Charging the car at home each night will provide enough power for daily driving and allow drivers to save time by avoiding stops at the gas station. And, as the number of electric cars on the road increases, more businesses and employers will install charging stations for their customers and employees, which will make charging a vehicle even easier.An electric car may not be for everyone, but they have evolved beyond their original restrictions. With a purchase price that is comparable to a gas car, and reduced fuel and maintenance fees, anyone who is purchasing a new car should seriously consider an electric car.
