Alona [7]

Answer:

$T = 3.23 \times 10^{-83}$

Explanation:

thickness of aerosol layer is 2.5 km

zenith angle is 40 degree

we know that

$\tau = \epsilon_{ext} . h$

where

$\epsilon_{ext} = N.\sigma_{ext}$

$\epsilon_{ext}$ is extinction coefficient

$\sigma_{ext}$ extiction cross section

N = Concentration

$\sigma_{ext} = (2.5 + 0.45)\times 10^{-12} m^2$

$= 2.95 \times 10^{-12} m^2$

$\epsilon_{ext} = 2\times 10^7 \times 2.95 \times 10^{-12} m^2 \times m^{-3}$

$= 5.9 \times 10^{-5} m^{1}$

$\tau = 5.9 \times 10^{-5} m^{-1} \times 2.5\times 10^3 m$

$= 14.75\times 10^{-2}$

transimiitance $T = e^{\frac{-\tau}{\mu}}$

$T = e^{\frac{- 14.75 \times 10^{-2}}{cos 40}}$

$T = 3.23 \times 10^{-83}$

Abundant ________ and ________ temperatures result in high rates of chemical weathering.

Fiesta28 [93]

Abundant moisture and warm temperatures result in high rates of chemical weathering.

Chemical weathering is due to rainwater reacting with the mineral grains in rocks to shape new minerals (clays) and soluble salts. these reactions arise especially while the water is slightly acidic.

Weathering breaks matter down into smaller portions. The motion of pieces of rock or soil to new places is known as erosion. Weathering and erosion can cause adjustments to the form, length, and texture of different landforms (together with mountains, riverbeds, seashores, and so forth).

The most important element of weathering is its role in the formation of soil. with out soil, existence, as we realize it on the earth, might not exist. Soil is a miles unnoticed element of earth's strategies and, at contemporary rates of human use and abuse, is becoming a finite useful resource.
