The graph shows the observed water levels, in feet (ft), for a tide gauge located at Montauk, New

York, on the easternmost end of Long Island, from January 24, 2008 to noon on January 25, 2008.

What causes the water-level variation pattern shown by the graph?

• Earth's rotation and the gravitational pull of the Moon

• changes in wind velocity produced by coastal storms

• changes in magnetic orientation of the North American Plate

• Earth's revolution and the distance from the equator

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

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
