Internet Webquest - Ozone

• What is Surface Ozone?

-               Surface ozone is formed when pollutants emitted by cars, power plants, refineries, & chemical plants, and other sources chemically react in the presence of sunlight.

• How does ozone both enable life on Earth and threaten life on Earth?

-               Stratospheric ozone filters potentially keeping ultraviolet light from reaching the earth’s surface and surface ozone is an air pollutant that has harmful effects on the respiratory systems of plants, animals and humans.

• How does surface ozone form?

-               Surface level ozone is produced in smog from combustion products.

• How does surface ozone affect health?

-               Breathing ozone can trigger a variety of health problems including asthma. Ground level ozone can also reduce lung function.

Surface Ozone is very harmful to the respiratory systems of plants, animals, and humans. Surface ozone is created whenever pollution from vehicles, power plants and chemical plants chemically react in contact with sunlight. Ozone enables life by keeping ultraviolet rays from reaching the earth’s surface; ozone blocks 100% of UVC rays, 90% of UVB rays, and 50% of UVA rays. Ozone threatens life because of surface ozone. Surface ozone is an air pollutant and it has harmful effects on the respiratory systems of plants, animals and humans. Surface ozone forms from combustion products. Ozone is terribly harmful to your health; it can cause many health problems such as asthma. Ground level ozone can reduce lung function. 

Internet Webquest - Aerosols

• What are aerosols or particulates?

-              Aerosols are tiny liquid or solid particles suspended in the air.

• What is the source of aerosols in the atmosphere?

-              Sources include volcanoes, sea spray, dust, smoke, wind erosion, ice particles, and pollen.

• How do aerosols affect the climate and climate change?

-              They can directly reflect sunlight back away from the Earth. They can interact with clouds in complex ways leading to changes in cloud reflectivity, cloud lifetime, cloud height and cloud precipitation.

• How do aerosols affect life on Earth?

-              The protective layers of the atmosphere, mainly the ozone layer and the ionosphere, are being shredded by the aerosol clouds. This threatens all life on planet earth exposed to dangerous levels of radiation.

Aerosols are very tiny solid particles or liquid particles suspended in the air as a gas. Aerosols come from many different things; they can come from volcanoes, sea spray, dust, smoke, wind erosion, ice particles, or even pollen. Aerosols have a heavy affect on climate and climate change. Aerosols can reflect sunlight away from earth, they can interact with clouds in different ways leading to changes in cloud reflectivity, cloud lifespan, the height, and the precipitation. Aerosols are destroying the ozone and the ionosphere, thus threatening any life on earth due to high levels of radiation. 

Teamwork Blog

I think my group worked well together. We had great communication, a little tough at first, but it progressed rapidly. We had great teamwork, we could always establish who was going to do what part of the project and help each other with anything we needed. We also had some pretty good results, our work turned out to be quite decent, and I had fun. A couple things that we could have done better would be our presentation. I’m sure our grade suffered because we did a terrible job presenting. We could have focused on our work a little more and put more effort into it, and I’m sure it would have turned out twice as good. We also could have worked at a little faster pace instead of finishing right at the deadline.
Notes Summary

Up to 99% of earth’s atmosphere is made up of atmospheric gases, including water vapor and they extend only 30 kilometers above earth’s surface. Most of our weather occurs in the first 10 – 15 kilometers. Clouds are not gas, but condensed vapor in the form of liquid. The lower the altitude the lower the pressure and as you get higher in the atmosphere it gets colder. The reason for higher pressures is because of pressure and density. Gravity pulls gasses towards earth’s surface, the gasses weigh 14.7 psi at sea level. Humidity is part of what make up clouds in the atmosphere. Humidity is measure of the amount of water vapor stuck between molecules in the air. The airs ability to hold water depends on the temperature of the air.
