Which of the following colors of visible light has the longest wavelength?

• Red

• Blue

• Green

• Orange

Where would a new star most likely form?

• in a nebula

• in a supernova

• in a black hole

• in an asteroid field

Which of the following conditions were not present during the formation of the solar system?

• It contracted.

• It was spinning.

• It flattened.

• It increased in mass.

What is the relationship between the distance from the Sun and the period of revolution for the planets in the solar system?

• The greater the distance from the Sun, the shorter the period of revolution.

• The greater the distance from the Sun, the longer the period of revolution.

• The distance from the Sun does not affect the period of revolution.

• The closer the distance to the Sun, the longer the period of revolution.

Which of the following is true about the planets in the solar system?

• All planets complete one revolution about every 365 days.

• All planets have one moon.

• All planets have an elliptical orbit.

• All planets have the same surface temperature.

Andromeda is the only known galaxy moving towards Earth at a speed of about km/s. How was the movement of the Andromeda galaxy towards Earth determined?

• By measuring the blueshift of its spectral lines.

• By measuring the redshift of its spectral lines.

• By measuring the widths of its spectral lines.

• By measuring the distance between its spectral lines.

Based on the spectral line diagrams provided, which statement best describes the movement of galaxies A, B, and C relative to Earth?

• Galaxy A is moving away from Earth, but galaxies B and C are moving toward Earth.

• Galaxy B is moving away from Earth, but galaxies A and C are moving toward Earth.

• Galaxies A, B, and C are all moving toward Earth.

• Galaxies A, B, and C are all moving away from Earth.

What did Edwin Hubble's discovery about the red shift of light from galaxies imply about the universe?

• The universe is contracting.

• The universe is static and unchanging.

• The universe is expanding and was denser in the past.

• The universe is cooling down rapidly.

What are the most abundant elements in the universe?

• helium and sodium

• carbon and nitrogen

• hydrogen and helium

• oxygen and hydrogen

As the planet makes one complete revolution around the star, the gravitational attraction between the star and the planet will:

• decrease, then increase.

• increase, then decrease.

• continually decrease.

• remain the same.
