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.
Planting grass and trees would stop erosion.
Answer:
Explained below
Explanation:
In physics, we know that waves usually change direction when are refracted or when they penetrate layers with different densities.
Therefore, when a seismic wave penetrates penetrates the boundary of the earth's interior, part of it will be sent back and part will be transmitted into the medium as refraction occurs. When we record the reflected and refracted ray, it enables the calculation of the position of major boundaries in the Earth's interior. This also helps in providing information about the solid & liquid character as well physical properties of the various layers in the medium.
