What causes the temperature to decrease with height in the troposphere?

1 answer:

3 0

We have all noticed that if we hike from a place with low elevation and go up at a place with high elevation, that the temperature is gradually dropping, thus giving us a clue that the lower places are warmer, while the higher places are cooler. The reason for this, even though both the places with low and high elevation are located in the troposphere, thus the same atmospheric layer, is that the density of it is not the same everywhere. The troposphere has the highest density at its lowest points, and as the height increase the density decreases. Since the higher parts are less dense, that means that there are less gases, thus there are less molecules that are further apart from each other. This results in lesser absorption of heat, so this parts are cooler, while the lower parts are warmer because the troposphere is denser, there's more molecules that are also closer to each other, thus they absorb more heat.

Under the heading of plate tectonics, there are three types of boundaries. In a convergent boundary, plates collide. True or Fal

Veseljchak [2.6K]

The answer is True. In a convergent boundary, two tectonic plates collide as they move in opposite directions, and there is a subduction zone where there are deep trenches. As the heavier tectonic plate, mostly the oceanic plate, is subducted, it enters the mantle and begins to melt. This makes magma that rises and erupts into a volcano in the overlying continental plate. This is how the Andes Mountains were formed.

Using Wien’s Law, estimate the wavelength at which these common materials radiate their peak brightness (show your work):

SSSSS [86.1K]

Explanation:

Wien’s Law:

$\lambda _{max}\propto \frac{1}{temperature}$

The law states that the wavelength at which black body emits maximum heat is inversely proportional to the temperature of the body in Kelvins.

$\lambda _{max}=\frac{2.9\times 10^{-3}}{T}$

1) Walls at 300 K

$\lambda _{max}=\frac{2.9\times 10^{-3} mK}{300 K}$

$\lambda _{max}=9.666\times 10^{-6} m$

2) Ice water at 273 K :

$\lambda _{max}=\frac{2.9\times 10^{-3} mK}{273 K}$

$\lambda _{max}=1.062\times 10^{-5} m$

3) Hot water at 373 K :

$\lambda _{max}=\frac{2.9\times 10^{-3} mK}{373 K}$

$\lambda _{max}=7.775\times 10^{-6} m$

4)Skin at 310 K:

$\lambda _{max}=\frac{2.9\times 10^{-3} mK}{310 K}$

$\lambda _{max}=9.355\times 10^{-6} m$

5)An incandescent light bulb at 3000 K

$\lambda _{max}=\frac{2.9\times 10^{-3} mK}{3000 K}$

$\lambda _{max}=9.666\times 10^{-7} m$

Chronic diseases are more common today than in the past in developed countries due to a decreased malnutrition b increased acces

allochka39001 [22]

The correct answer is - e. longer life expectancy.

The chronic diseases most commonly affect the older population, due to the weakening of the body as it gets into the latter stages of its existence. Since the life expectancy has increased significantly in the last century, and it is further increasing, even though with lower tempo nowadays, there's more and more people that reach older life, thus the number and percentage of the chronic diseases is ever-growing, especially in the developed countries where the population is in general aging as well.

Why is the Eastern terai of Nepal cooler than the Western one?

Hitman42 [59]

Answer:The eastern Terai is cooler than the western one because it is closer to the sea (Bay of Bengal).
