An aquifer is the most expected feature that is likely to be reach after drilling through the unsaturated zone. Aquifer has tendency to transform ground water to the surface through voids. The depth of aquifer varies.
West to east.
The earth is spinning on its own axis. Thus, the area of the equator directly hit by the sun's heat and more solar radiation compared to any other area. That same heat warmth the atmosphere. Warm air rises towards the pole which is cooler. This is the reason of constant movement of the atmosphere.
The Coriolis force governed the air flows towards the pole. While the earth is spinning plus the movement of air north or south, the air follows a <span>curved path, toward the east.</span>
The answer is; E
The key word is photochemical smog that differentiated it from industrial smog that are formed from different conditions. Photochemical smog is majorly driven by the sun that splits nitrogen oxide pollutants in the air into nitrogen and oxygen. The oxygen forms OH radicals with the water vapour in the air. The OH forms radicals with hydrocarbons pollutants in the air which ultimately form aldehyde peroxides that are a health risk.
I think unbalanced forces is one of the reasons
