Astronomy

Which list shows stars in order of increasing temperature?

• Barnard's Star, Polaris, Sirius, Rigel

• Aldebaran, the Sun, Rigel, Procyon B

• Rigel, Polaris, Aldebaran, Barnard's Star

• Procyon B, Alpha Centauri, Polaris, Betelgeuse

A blue shift of the light from a star indicates that the star

• will soon become a giant star

• is moving away from Earth

• will soon become a main sequence star

• is moving closer to Earth

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

Evidence that the universe is expanding is best supported by the observation that the wavelengths of light from distant galaxies are shifted toward the

• blue end of the spectrum because they are lengthened

• red end of the spectrum because they are lengthened

• red end of the spectrum because they are shortened

• blue end of the spectrum because they are shortened

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

as seen by an observer in New York State on the first

day of one of the four seasons.

This apparent path of the Sun was observed on the first day of

• winter

• summer

• spring

One factor responsible for the strength of gravitational attraction between a planet and the Sun is the

• degree of tilt of the planet's axis

• planet's period of rotation

• amount of insolation given off by the Sun

• distance between the planet and the Sun
