Answer:
The stratosphere is located above the troposphere and extends up to about 50 km (30 miles). Above the tropopause and the isothermal layer in the lower stratosphere.The stratopause caps the top of the stratosphere, separating it from the mesosphere near 45–50 km (28–31 miles) in altitude and a pressure of 1 millibar, The stratosphere altitude is still high, though. It extends from about 6 miles (10 kilometers) to about 30 miles (50 kilometers).
In the mesosphere, temperatures again decrease with increasing altitude. Unlike the situation in the stratosphere, vertical air currents in the mesosphere are not strongly inhibited. Ice crystal clouds, called noctilucent clouds, The stratosphere altitude is still high, though. It extends from about 6 miles (10 kilometers) to about 30 miles (50 kilometers).
