Which two layers of the atmosphere are characterized by decreasing temperatures with increasing altitude?
a
troposphere, mesosphere

b
stratosphere, thermosphere

c
troposphere, thermosphere

d
stratosphere, mesosphere

A

Explanation:

The troposphere gets its heat from the ground, and so temperature decreases with altitude. Warm air rises and cool air sinks and so the troposphere is unstable. In the stratosphere, temperature increases with altitude. The stratosphere contains the ozone layer, which protects the planet from the Sun's harmful UV.

A  troposphere, mesosphere

Explanation:

Temperature decreases with altitude in two of Earth's atmospheric regions: the troposphere and the mesosphere. The troposphere is the region closest to the ground, and the mesosphere is just above the ozone layer.

the great wall of china worked as a defense for the feudal states of the zhou dynasty to the north. during the warring states period more walls were put up to defend the borders of the different kingdoms. it was semi successful because despite the wall, the mongols eventually conquered china also the great wall provided protection to the economic development and cultural progress, safeguarded the trading routes such as the silk road, and secured transmission of information and transportation. @jayxboof
