Answer: Option (B) and (F)
Explanation:
Pressure and Density, both are inversely proportional to the height.
The air molecules are mostly present near the surface because of its higher density and the gravitational force that forces them to accumulate near the earth's surface. And as we go up, these air molecules gradually decreases in number and their density also becomes very less, as a result of which the pressure and density both subsequently reduces.
Thus, the correct options are mentioned above, i.e the pressure as well as density both decreases with the increasing height.
Answer with Explanation:
The amount of groundwater that can be stored will largely depend on the <em>"soil's permeability." </em>A permeable soil means that <u>it is easy for water to pass through the pores.</u> It has<em> </em><em>larger pores that are well-connected to each other</em> thereby allowing water to flow freely. This also allows the water to pass through the rocks, which then <u>increases its </u><u>porosity</u>. This also leads to an easier way to extract the groundwater.
Answer:
Explanation:
Xinjiang's growing population has increased its demand for water for industry and irrigation, raising concerns that the supply of water to Lake Balkhash could be drastically reduced. This would affect not only the population around the lake, but the entire Ili-Balkhash river basin where around one fifth of Kazakhstan's population lives.
