A star will reach it's Old Age Stage when all the _______________ in it's core is used up as fuel

• hydrogen

• helium

• carbon

• uranium

When all the fuel in a star's core is used up, fusion outside the core will cause it to expand and become a ___________________ star.

• Red Giant

• White Dwarf

• Purple Meany

• Black Hole

When our sun finally runs out of fuel, gravity will cause it to collapse and form a ____________________ star.

• Red Giant

• White Dwarf

• Neutron

• Black Hole

One teaspoon of material from a White Dwarf Star will weight :

• 5 pounds

• 500 pounds

• 5 tons

• 1 million tons

Clouds of material thrown off by a shrinking Red Giant star are called :

• gas jets

• ion trails

• dust tails

• nova

When a Red Super Giant star runs out of fuel , it will collapse so hard that an explosion known as a _________________ will occur.

• Pyrotechnic Display

• Aurora

• Supernova

• Quasar

The extremely small remains of a collapsed Super Red Giant so dense that a teaspoon of material can weigh up to 1 billion tons is called a (an)

• White Dwarf

• Black Dwarf

• Neutron Star

• Quasar

When the largest stars collapse, their gravity becomes so great that not even light can escape. These dead stars are now called

• Red Giants

• White Dwarfs

• Pulsars

• Black Holes

What is one way Black Hole stars can be detected ?

• with the use of optical telescopes

• with instruments called "Black Hole" detectors

• by observing x-rays given off by a neighboring star as it is sucked into the black hole

• they cannot be detected because they cannot be seen

The H-R diagram is a chart which plots stars on it according to their _____________________________________

• size and volume

• temperature and brightness

• age and type

• distance from the Earth
