A rendering of the magnetic field lines of Earth's magnetosphere.

Near the surface of many astronomical objects, the magnetic field resembles that of a dipole.
The largest net source of tropospheric ozone is influx from the stratosphere. Large amounts of ozone are also produced in the troposphere by photochemical reactions, the amounts increasing with high levels of air pollution.Much of this ozone, though, is balanced by photochemical ozone destruction.he largest net source of tropospheric ozone is influx from the stratosphere.
