The 289 area code was created as an area code overlay for the Mississauga (Streetsville) area. Unlike the previous solutions, this process did not require the place to be geographically separated by different area codes.
Ionizing radiation is a term used for radiation whose quanta have energy to directly or indirectly ionize (one or more electrons are released from the atom of the given substance) molecules or atoms while passing through matter, hence the name ionizing radiation.
Part of this radiation is directed towards the surface, warming it. The intensity of the downward radiation â that is, the strength of the greenhouse effect â will depend on the atmosphere's temperature and on the amount of greenhouse gases that the atmosphere contains. Earthâs natural greenhouse effect is critical to supporting life.
