Answer:
There are two reasons: at higher altitudes, there is less air pushing down from above, and gravity is weaker farther from Earth's center. So at higher altitudes, air molecules can spread out more, and air density decreases
From 1922-1991, Russia would have been considered a autocratic state.
When studying the Calumet region of Illinois and Indiana, Alfred Meyer noted four stages of development as new groups occupied this land. In stage 4, conurbanization, new cities spread across new territories and grew toward one another. (Option C)
<h3>What is the Calumet Region about?</h3>
The Calumet Region is the geographic area in the United States drained by the Grand Calumet River and the Little Calumet River in northeastern Illinois and northern Indiana. It is a component of the Great Lakes Basin, which leads to the Atlantic Ocean.
A conurbation is an urban region formed when two or more cities merge, as in Osaka-Kobe-Kyoto, Essen-Dusseldorf (the "Rhine-Ruhr-Wupper"), or Katowice-Gliwice (Poland). While Agglomeration is the region around the city centre that extends beyond the city core.

The line of sight from earth to the star system must be very close to the orbital plane of the stars to see eclipses of stars in binary star systems.
Each star in a double star system, also known as a binary star system, gravitationally pulls in the second star, which circles around the pair's centre of mass. Each star will be seen to eclipse the other once every orbital period if their orbital plane is edge-on to Earth. Eclipsing binary is the name for such a system.
It is also referred to as an eclipsing variable star because in an eclipsing binary system, the total amount of light fluctuates on a regular basis. When one of the two stars in an eclipsing binary is eclipsed, the light curve of the system experiences a deep minimum, and when the other star is eclipsed, the light curve experiences a shallower minimum.
