Physical geography focuses on geography as a form of earth science. It tends to emphasize the main physical parts of the earth – the lithosphere (surface layer), the atmosphere (air), the hydrosphere (water), and the biosphere (living organisms)—and the relationships between these parts.
The greenhouse gas raises the temperature by trapping the earth radiant heat inside the atmosphere and warming also increases the accumulation of the atmospheric water and most abundant in the greenhouse gases. And this accelerates the greenhouse effects.
