ASTRONOMY 1 Quiz Review

The universe is approximately 13.8 billion years old. Compared to the age of the solar system, the age of the universe is approximately

• the same age as the solar system

• 2x older than the solar system

• 3x older than our solar system

• 4x older than our solar system

Planets that are closest to the Sun are identified as

• low-density jovian planets

• low-density terrestrial planets

• high-density jovian planets

• high-density terrestrial planets

The diagram below represents the light spectra given off by the same element as observed under two different conditions. Spectrum A was observed when that element was heated in a laboratory. Spectrum B shows the same element as seen in the light from a distant star.

The light spectrum observed from this distant star shows a

• red shift, which indicates that the star is moving away from Earth

• blue shift, which indicates that the star is moving away from Earth

• blue shift, which indicates that the star is moving toward Earth

• red shift, which indicates that the star is moving toward the Earth
