Multiple Choice

(38%) Nicolaus Copernicus and Johannes Kepler were two important astronomers who each developed a model of the Solar System.

How did Kepler's model compare to Copernicus's model?

• Like Copernicus, Kepler proposed a geocentric model, but Kepler also proposed circular orbits.

• Like Copernicus, Kepler proposed a geocentric model, but Kepler also proposed elliptical orbits.

• Like Copernicus, Kepler proposed a heliocentric model, but Kepler also proposed circular orbits.

• Like Copernicus, Kepler proposed a heliocentric model, but Kepler also proposed elliptical orbits.

Multiple Choice

(47%) In 1929, Edwin Hubble discovered that the universe is constantly expanding. He measured the speed that galaxies outside the Milky Way were moving away from our location on Earth and concluded that there was a moment in time when the universe was all contained in one dense location. Hubble's discovery, along with the work of Albert Einstein and other scientists, contributed to the Big Bang Theory. Today, NASA sends spacecraft into space to continue to explore this expansion of the universe.

Which statement best describes empirical evidence being used to explain the formation of the universe?

• NASA scientists send satellites to collect images of Earth's surface from space.

• NASA scientists debate the possibility of the future reversal of the universe's motion.

• NASA scientists review the criteria for classifying an object in the universe as a planet.

• NASA scientists study background radiation and determine the changing shape of the universe.
