BBT and Historical Models QC Review

In a classroom discussion, Milo mentioned the ________ model, which is a model proposed by Nicholaus Copernicus, a Polish cleric, around 1500. His model proposed that all the planets revolve around the Sun and the moon revolves around Earth.

During a science fair, Milo and Belle presented a project on the Big Bang Theory. They explained that Edwin Hubble is credited for the initial development of the theory, an idea that helped explain the formation of the universe over 15 billion years ago. Which piece of evidence did Hubble find that led him to begin the development of the Big Bang Theory?

For what reason did the heliocentric model of the universe replace the geocentric model of the universe, as explained by Milo in his science project?

• The geocentric model no longer predicted the positions of the constellations.

• The heliocentric model proved that the Earth rotates.

• The heliocentric model provides a simpler explanation of the motions of the planets.

• The geocentric model did not predict the phases of the moon.

During a history class, Sirius and Milo learned that the ____________ model was first summarized by Aristotle and Plato in the 4th Century BC and later updated by Ptolemy, a Greek philosopher, about 100-200 AD. In the model, the Earth is motionless at the center of the universe.

During a science class, Milo observed that interstellar bodies are moving away from Earth, some faster than others. This observation BEST suggests that the universe

• is shrinking.

• is expanding.

• was not formed by a big bang.

• has always been the same size.
