Stratification helps the civil engineer to:
a- properly understand the nature of the ground and know what is underlying this ground, whether solid rocks or soil
b- develop an understanding of the permeability of the composite soil
c- develop an understanding of the mechanical properties of the ground such as its strength
d- ensure that the site is properly structured and suitable for the targeted project<span />

Earth's Second Atmosphere The second atmosphere, which was the first to stay with the planet, formed from volcanic outgassing and comet ices. This atmosphere had lots of water vapor, carbon dioxide, nitrogen, and methane but almost no oxygen.
The two gasses in the troposphere that play vital role in heat absorption are the water vapor and the carbon dioxide. Both of them are gasses that trap both part of the solar heating, and part of the Earth's heating, and they play a vital role in the regulation of the temperature on the Earth with the process better known as ''Greenhouse effect''.
