To it by conduction, convection and radiation. Air pressure decreases with height as the effect of gravity weakens, although wind speeds usually increase with height. The troposphere is inherently unstable. It contains most of the atmosphere’s water vapour, dust, cloud and a mixture of natural and anthropogenically-produced gases. At the tropopause is a layer extending from around 12 to 20 km at which temperatures remain constant despite increasing height. This layer is known as an isothermal layer.
Understand the location, processes and function of stratospheric ozone and the threats to its existence. ➤ Understand the importance of variable greenhouse gases like carbon dioxide, methane, nitrous oxide, ozone and other pollutants and how they vary over space and time. ➤ Describe the sources of aerosols and understand the causes and effects of acid rain. 1 Structure of the atmosphere The word ‘atmosphere’ is derived from the ancient Greek words atmos (meaning vapour) and sphaira (meaning sphere).
