The atmosphere extends a few hundred kilometres above the Earth. It is made of layers that surround the Earth like rings. These two regions are called the troposphere and the stratosphere. The troposphere is closest to the Earth.
Depletion of the ozone layer: causes, status and recovery - britanskiovcari.info
Summarize what have learned from your readings and submit your work to the Canvas assignment page. While the scope of scientific writing styles has expanded in the past decade, we will narrow it for this class to include the following elements. When you state the work that was done, this is reported in the past tense. This can also be applied to the results, discussion, and conclusion sections when data were analyzed and conclusions were made. When you talk about the future work to be done, then use the future tense. Even though the assignments are graded by TAs who are graduate students, they are not your intended audience.
NASA reports Arctic stratospheric ozone depletion hit record low in March
The stratosphere is responsible for many processes influencing weather, climate and environment on Earth. Most noticeable is the impact of the ozone layer on nature and human civilization, but it is also becoming increasingly evident that stratospheric processes have large impact on the tropospheric climate. At the DMI research is performed by monitoring stratospheric composition through balloon measurements, satellite retrievals and ground-based remote sensing. Process studies on mesoscale as well as cloud modelling on microphysical scale is performed in international collaborations. Models are used for assistance of monitoring activities, process studies and climate studies.
The great depression had affect Canada socially, as population changes occurred, as less immigrants go to canada, and birth rate changes, as well as death rates. The lowest ratio until the s. TBHQ had no effect on bacterial viability for the first min of the experiment, but killing was observed thereafter. TBBQ was rapidly and extensively bactericidal, causing 5 log10 drop in cell number within 3 h.
