Stalin ruled by terror and with a totalitarian grip in order to eliminate anyone who might oppose him. He expanded the powers of the secret police, encouraged citizens to spy on one another and had millions of people killed or sent to the Gulag system of forced labor camps. During the second half of the 1930s, Stalin instituted the Great Purge, a series of campaigns designed to rid the Communist Party, the military and other parts of Soviet society from those he considered a threat.
Answer:
As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons.
But Earth's distance from the sun doesn't change enough to cause seasonal differences. Instead, our seasons change because Earth tilts on its axis, and the angle of tilt causes the Northern and Southern Hemispheres to trade places throughout the year in receiving the sun's light and warmth most directly
Relatively speaking, Earth's distance from the Sun doesn't change all that much throughout the year, nevertheless there are measurable differences in solar heating that result from our planet's slightly elliptical orbit.
