Solar nebula theory describes...

• how nebulas form

• how black holes form and the stars inside them

• how galaxies form

• how stars form and the planets that orbit them

Massive clouds of dust inside galaxies provide the ingredients for stars to form. These stellar nurseries are called a ...

• nebula

• black holes

• white holes

• solar farms

The dust and gas in a nebula will collapse and stick together to form a proto-star. This happens because of high energy waves from a nearby....

• black holes

• Jupiter

• supernova

• space weather

Early stars that are just forming are called...

• plantesimals

• protoplanets

• protostars

• protopronto

TRUE or FALSE.....the large ring of gas and dust surrounding a protostar is called its accretion disk

• TRUE

• FALSE

Its the gas and dust swirling around a young protostar that will eventually form small

• nuetrinos

• atoms

• protons

• planetesimals

Planetesimals will grow larger and larger, becoming massive enough to attract more gas and dust making them into planets

• TRUE

• FALSE

Planets orbiting a young star can

• collide with other planets destroying them

• get sucked back into the young star

• be thrown out of the orbit and into deep space

• All of the above

When a young star finally ignites and starts nuclear fusion it creates a wave of energy that

• forms a black hole

• clears a lot of the gas and dust orbiting close to it

• develops figure eight orbit

• collapses in on itself
