Which of the following is used to calculate the distance to a star based on subtle shifts in the star's position relative to an observer on earth? a) absolute magnitude. b) doppler shift. c) emissions. d) parallax

Out of the choices given, the Parallax is used to calculate the distance to the star based on subtle shifts in the star's position relative to an observer on Earth. The correct answer is D.

The horse latitudes-high-pressure zones about 30 degrees north and 30 degrees south of the equator.-warm air traveling away from the equator cools and sinks-weather tends to be clear and drythe doldrums-low-pressure near equator-air rises and spreads out toward the poles-rising moist air produces clouds and heavy rainthe westerlies-blow from the west-move from the horse latitudes toward the poles.-bring storms across much of the united statesthe tradewinds-blow from the east-move from the horse latitudes toward the equator  -strong, steady winds
