As the air over the earth surface gets warmed due to the solar radiation coming from the sun which directly heats the upper atmosphere of the earth and thus the air gets heated up and rest light or energy is absorbed by the ground and reflected into the atmosphere.
Similarly, the altitude has a major role to play in this process as the place near the tropics and equator air is less dense and hence higher absorption as compared to the higher latitudes the air becomes denser and hence lear absorption takes place.
Also with regards to the atmospheric cloud patterns the earth temperatures changes as these bring winds and rainfall and these cool the temperature over the hotter places like air moves from high pressure to low pressure and visa Versa.
As the crust of the San Andrea is continuously moving due to the tectonic activity and is the main manifest of the tectonic boundary of the North America and the pacific plate. This fault along with the pacific plate will move towards the Los angles and eastern San Francisco as it moves about 3.5 cm per year.
As 1 km equals to about 100 000 cm
, then the distance of 620 km = 62, 000,000 cm and 62,000,000 will be divided by 3.5 equal to 17. 71 years to collide with the eastern side.
