👉 The term "trophosphere" refers to the layer of gases in Earth's atmosphere above the surface, which is composed primarily of nitrogen and oxygen. This layer is known for its high concentration of greenhouse gases like carbon dioxide (CO2) and methane (CH4), which trap heat from the sun and contribute to global warming. The troposphere plays a crucial role in the climate system by regulating air temperature and humidity, providing the necessary conditions for clouds and precipitation. It also affects weather patterns,
