THE GEOCENTRIC MODEL
Ancient scientists believed in the geocentric model, which stated that
Earth was the center of the solar system, as evidenced by the motion of
celestial bodies throughout the sky each day. However, as knowledge and
technology improved, other ideas began to emerge. With the advent of the
telescope, the path of the solar system's bodies could be more accurately
determined. New evidence began to emerge, and eventually a new theory,
the heliocentric, or Sun-centered, solar system, was developed.
Why did the knowledge about Earth's position in the solar system change?
A. Because scientists could not find enough evidence to support their original solar
system theories.
B. Because celestial bodies changed their positions in space and eventually Earth
orbited the Sun.
C. Because new technology gave scientists new evidence that changed their
interpretation of celestial movement.
D. Because new technology made it easier for scientists to think of more plausible
stories to describe natural events.
