Sol. It contains most of our weather – clouds, rain, snow. In this part of the atmosphere the temperature gets colder as the distance above the earth increases, by about 6.5°C per kilometer.

Because of this, few clouds are found in this layer; almost all clouds occur in the lower, more humid troposphere.
Sol. A barometer is a scientific instrument used to measure air pressure.
