Star Review Guide

What is a cloud of dust and gas called (from which all stars are formed)?

• protostar

• nebula

• main sequence

• supernova

Choose the option that indicates the stages all stars go through.

• nebula, protostar, main sequence, giant stage

• nebula, protostar, main sequence, supernova

• nebula, main sequence, supernova, black hole

• main sequence, supernova, neutron star

How is a main sequence different from a protostar?

• A protostar fuses hydrogen; a main sequence fuses helium

• A protostar comes at the end of a star's life; the main sequence at the beginning.

• A protostar doesn't undergo nuclear fusion in its core; main sequence does

• A protostar has layers of elements in it; a main sequence doesn't.

When a star forms, what elements is it made of?

• Hydrogen and Carbon. Carbon is in the core.

• All elements 1-26 (Hydrogen to Iron)

• Hydrogen and Iron. Iron is in its core.

• Hydrogen and Helium

  (mostly Hydrogen)

If a black hole is formed, what is a likely start of the star?

• The most massive average-sized star (a little bigger than our sun)

• A high-mass star, but not as massive as the most massive ones.

• The most massive high-mass stars.

• A red dwarf

What elements were made in the Big Bang?

• Uranium, Plutonium, Thorium

• Carbon, which quickly changed to Helium

• Hydrogen, Helium, Lithium, Beryllium, Boron, Carbon

• Hydrogen and Helium

• H (1)-Fe (26)

• H and He only

• H (1) - U (92)

• H (1) to C (6)
