Respuesta :
According to all the given requirements
stratosphere x starts at an altitude of 16 km
that means
16≤xand,as given ,stratosphere ends at an altitude of 30 km:
which means
x≤30 combining both of them we get
16≤x≤30 So the range of the stratosphere is from 16 to 30 km.
Answer:
The Stratosphere layer is the layer next to the troposphere and it extends from an elevation of about 10-15 km to 50-60 km above the surface of earth. In this layer, the temperature increases with the increasing height. This increase in temperature is because of the presence of the ozone. This ozone is also called good ozone as it protects the lives on earth from the harmful ultraviolet radiations emitted from the sun.
In order to show the elevation range of the stratosphere layer, in the form of compound inequalities, we take two equations from the given data-
=> X ≥ 16 -------- (equation 1), where X= thickness of the stratosphere layer.
=> X ≤ 50 -------- (equation 2)
Now, from equation 1 and equation 2, we have,
=> 16 ≤ X ≤ 50
So, in conclusion, we can say that the thickness of stratosphere ranges from 16 to 50 km.
