Question

it was believed that earth was a stationary object at the center of the universe. all other objects in space were thought to go around earth. which of these is a criticism of this idea? a years on earth are regular periods of three hundred sixty - five days each. b earths shadow falling on the moon shows that earth is actually spherical, rather than flat. c the moon, goes around earth, resulting in different phases of the moon that can be seen from earth. d there are four seasons on earth only because earth is tilted at its axis and it goes around the sun.

Explanation:

La idea de que la Tierra es el centro estacionario del universo es incompatible con la idea de que la Tierra gira alrededor del sol y que hay estaciones debido a la inclinación de su eje mientras orbita. Las opciones B y C son hechos astronómicos correctos pero no son críticas a la idea de la Tierra estacionaria en el centro del universo. La opción A es una característica de la Tierra pero tampoco es una crítica directa a la idea geocéntrica. La opción D muestra que la Tierra se mueve alrededor del sol, lo cual es una crítica a la idea de la Tierra estacionaria en el centro del universo.

Answer:

D. There are four seasons on Earth only because Earth is tilted at its axis and it goes around the sun.
