Life Cycle of a Star

What stage of the life cycle of a star is this?

• Main Sequence

• Red Giant

• Black Hole

• Neutron star

In a large mass star, the temperature reaches more than 100 billion degrees. The repulsive forces between the iron nuclei cause a massive explosion sending the star’s mass into space in a ....

• Supernova

• Nova

• Black Hole

• Pulsar

The longest period of a star’s life is called...

• Main Sequence

• Red Giant Phase

• White Dwarf Stage

• Supernova Phase

A series of bursts that create a cloud of gas and dust in outer space ejected by an aging star near the end of its life cycle. What stage in the life cycle is this describing?

• Planetary Nebula

• Supernova

• Red Giant

• Main Sequence

Larger stars (stars with more mass) have a longer life cycle. True or False?

• True

• False

• It depends on the star's composition

• Larger stars have shorter life cycles

What fuel do stars use?

• Oxygen

• Hydrogen

• Carbon

• Iron

The remains from its supernova will form a rapidly spinning, highly magnetic star called a...

• Neutron star

• White dwarf

• Black hole

• Red giant

What stage in a star's life cycle is described by gravity pulling gases and dust particles toward one another, squeezing them into a smaller space, leading to nuclear fusion of hydrogen?

• The birth of a star

• The death of a star

• The main sequence phase

• The red giant phase

What determines the color of a star?

• Its size

• Its distance from Earth

• Its temperature

• The amount of gas it contains

In the death of a large mass star gravitational collapse is so complete that no energy or matter can escape. This is called a...

• White Dwarf

• Neutron Star

• Black Hole

• Red Giant
