The Structure of the Universe

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

• a single constellation

• the milky way galaxy

• the solar system

• a giant cloud of gs

The theory that the universe is expanding is supported by data from the

• nuclear decay of radioactive materials

• nuclear fusion of radioactive materials

• blue shift of light from distant galaxies

• red shift of light from distant galaxies

A red shift in the light from very distant galaxies suggests that the universe is

• Fixed and Stationary

• Moving randomly

• contracting

• expanding

In which sequence are the items listed from least total mass to greatest total mass?

• solar system, Milky Way, universe

• Milky Way, solar system, universe

• universe, Milky Way, solar system

• Milky Way, universe, solar system

Which statement best describes the age of our solar system and the universe?

• The universe is at least twice as old as our solar system.

• Our solar system is at least twice as old as the universe.

• Our solar system and the universe are estimated to be 5 billion years old.

• Our solar system and the universe are estimated to be 10 billion years old.

A lightyear is

• the distance traveled by light in one year

• the distance the Earth moves in one year

• the time it takes light to go once around the Earth's orbit

• the time it takes light to travel one year

Billions of stars in the same region of the universe are called

• Solar systems

• asteriod belts

• constellations

• galaxies

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

• will soon become a main sequence star

• will soon become a giant star

• is moving closer to Earth

• is moving away from Earth

The more that the spectral lines of a star are shifted to the red end of the spectrum

• the larger it is

• the faster it is rotating

• the hotter it is

• the faster it is moving away from us

• conduction

• convection

• radioactive decay
