Life Cycle of stars AQA GCSE Physics

Stars are formed from big clouds of gas and dust is known as:

• dust cloud

• space fog

• neutron clouds

• nebulae

The only force acting on the nebulae is:

• thermal expansion

• singularities

• gravity

• microscopic adhesion

A star is born when:

• nuclear fusion starts

• a nebula becomes a protostar

• gases in a nebula condense

• hydrogen is used up in fusion processes

When the core of a Red Giant collapses it becomes a:

• White Dwarf

• Supernova

• Red Supergiant

• Black Hole

When a massive star begins to cool and expand it is known as a:

• Black Dwarf

• Red Giant

• Red Supergiant

• White Dwarf

When the core of a Red Supergiant collapses, a bright event occurs, known as:

• white dwarf

• supernova

• big bang

• black hole

Our sun is currently in what star stage?

• Protostar

• Nebula

• Main Sequence

• Red Giant

A black hole is black because:

• there is nothing in it

• it is too small to see

• it is inherently evil

• even light cannot escape its gravity

One possible outcome that is left after a supernova is a super dense core called a:

• Neutron Star

• White Dwarf

• Red Giant

• Black Dwarf

After a supernova, the core can collapse into a neutron star, or if massive enough it can become a:

• Black Hole

• White Dwarf

• Red Supergiant

• Black Dwarf
