Why does not air show same composition all over place?

No composition of air doesn't remain the same. It changes with the altitude and latitudes over which the atmospheric layers are placed. In fact this is one of the reasons behind the division of atmosphere into layers, namely- Troposphere, Stratosphere, Mesosphere, Ionosphere and Exosphere.

In the lower most layer- the Troposphere (up to 8 to 20 kilometers high from earth surface; highest at the equator and lowest at the poles) and the next layer- the Stratosphere (up to 50 kilometers), composition of air remains almost the same. But the ratio of water vapor and other solid particles vary with height and region.

Water vapor is generally lower in the Stratosphere (proportional to total atmospheric pressure, which reduces with height throughout the depth of the atmosphere) than in the Troposphere and there is a significant area of ozone in the Stratosphere at about 30–35 kilometers (popularly know as Ozone layer). There is generally a greater concentration of ozone (triatomic oxygen gas) throughout the Stratosphere than in the Troposphere. The "ozone layer" strongly absorbs far ultraviolet radiation (very short wavelengths of light from the Sun), resulting in a slight increase in temperature with altitude in the Stratosphere. The Stratosphere is either non-existent or very hard to detect at the poles.

Answer: because some places are at higher altitudes and some are lower . As we know higher the altitude lower the pressure , and many more are there , therefore air cannot able to show same composition
