2. Free Air and Bouguer Gravity Anomalies The observed gravity field after correction (corr) for latitude (theoretical gravity) and topography is known as the free air gravity anomaly, or simply the free air anomaly (Δgf), which is given by: Δgf = observed gravity – tidal corr – theoretical gravity + topographic corr + free air corr (1)
Physical Geography I and introduces the basic concepts of Biogeography, mainly concerned with the factors that determine the distribution of living organisms and their impact on the environment.
THE ATMOSPHERE GEOGRAPHICAL KNOWLEDGE Winds Wind is air movement across the surface of the Earth. On a simple, non-rotating Earth, made up of land (or water) only, warm air would rise at the equator and move towards the poles, where it would sink towards the surface. At the surface, air would return from the poles towards the

Air. Doyouknow? Carbon dioxide released in the atmosphere creates a green house effect by trapping the heat radiated from the earth. It is therefore called a greenhouse gas and without it the earth would have been too cold to live in.
