Document Summary
The study of body of knowledge using a practice. Start with an observation and go from there! Ozone keeps out harmful uv rays in stratosphere. Cfcs are broken down by uv rays, and chlorine attacks ozone. Original observation is the ozone is depleting in the spring. Also noticed higher cfc concentration in the atmosphere (correlation) Hypothesis was cfcs are depleting the ozone. Cfcs are resistant and not found in the natural world. See that the ozone is thinning at a rate unprecedented by studies done by. Polar vortex forms clouds in the stratosphere. Sent balloons up to measure clo in the atmosphere v. height. Also measure sunlight to measure solar radiation (uv-b) Also measure the amount of nox and ozone. Observed: ozone down, clo up; nox down. Suggest since there is little nox, nox isn"t breaking down the ozone with sunlight. Clo increase suggests cfc via clo is attacking the ozone.
