1st Half Astronomy

Base your answer to the following question on the diagram below and on your knowledge of Earth

science. The diagram represents Earth in its orbit around the Sun. Locations A through D represent four

positions of Earth in its orbit. Earth is closest to the Sun (perihelion) at position A, and farthest from

the Sun (aphelion) at position C.

At all four positions, the northern end of Earth's axis points toward

• Betelgeuse

• the Sun

• the Moon

• Polaris

Earth, the Sun, and billions of stars are contained within

• a single constellation

• a giant cloud of gas

• the solar system

• the Milky Way galaxy

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

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

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

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

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