How does air pressure change as altitude increases in the atmosphere?

Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.

The higher the altitude, the lower the atmospheric pressure. Lower pressure in turn causes water to evaporate more quickly, and water actually boils at a lower temperature. The percentage of oxygen in the air at two miles (3.2 km.) is the same as at sea level (21%). However, the air pressure is 30% lower at the higher altitude due to the fact that the atmosphere is less dense--that is, the air molecules are farther apart. The important effect of this decrease in pressure is this: in a given volume of air, there are fewer molecules present. This is really just another way of saying that the pressure is lower. This is called Boyle's law.

Compared with normal pressured shales, which one of the following features can be found in overpressured shales? O A. Lower dens

Nitella [24]

Answer:

(a) Lower densities and higher thermal gradient

Explanation:

Over pressured zones during penetrating are those zones where development liquid weight (higher than expected) surpasses the mud weight. These are liable for victories.

The pore liquid substance in shales of the over constrained zone is higher than the ordinary compelled shales. That implies, the porosity of shales in over pressured zone is higher as well thus the thickness of the over forced zones are lower than the ordinary influenced shales.

Because of the nearness of more liquids in the pores of an over constrained shale, the warmth produced because of penetrating behaviors gradually in over influenced shale than a shale in typical weight zones. Accordingly, warm inclination will be higher in over forced shales.

Explanation:

The US Geological Survey, which was established as far back as 1879, is a US Government Agency whose mission is stated as: "We provide science about the natural hazards that threaten lives and livelihoods, the water, energy, minerals, and other natural resources we rely on, the health of our ecosystems and environment, and the impacts of climate and land-use change. Our scientists develop new methods and tools to enable timely, relevant, and useful information about the Earth and its processes."
