Roughly 7! 7 x 48 is 336 which is two short so maybe just say 8 to be safe.
This process is known as thermohaline circulation. In the Earth's polar regions ocean water gets very cold, forming sea ice. As a consequence the surrounding seawater gets saltier, because when sea ice forms, the salt is left behind. As the seawater gets saltier, its density increases, and it starts to sink.
Well the altitde in <span>the atmosphere in which the stratospheric ozone can be found is 82 km. So the closest would be 70 km.</span>
Ozone molecules.
Ozone is a gas that is naturally present in our atmosphere, mostly in a region of the stratosphere, also known as the ozone layer. It's between about 10 km and 50 km above the surface of the earth and <span>extends
over the entire globe with some variation.
</span>The ozone in the s<span>tratosphere is considered good because
it absorbs ultraviolet- B (UV-B) radiation from the Sun . If not absorbed,
radiation would reach Earth’s surface in higher amounts that would be more harmful.</span>
