Star Cycle Grade 5 Quiz

How does a star form?

• A star forms from a volcano eruption on a planet.

• A star forms from a black hole collapsing.

• A star forms from a giant asteroid crashing into a planet.

• A star forms from a cloud of gas and dust called a nebula.

What are the main components involved in the formation of a star?

• Magnetism, electricity, and light

• Rocks, trees, and sunlight

• Gas, dust, and gravity

• Water, air, and heat

What are the different stages in the life cycle of a star?

• Sun, Moon, Earth, Mars, Jupiter

• Nebula, Protostar, Main Sequence, Red Giant or Supergiant, Planetary Nebula or Supernova, White Dwarf or Black Hole

• Seed, Sprout, Tree, Fruit, Flower

• Infant, Toddler, Teenager, Adult, Senior Citizen

Explain the process of nuclear fusion in stars.

• Nuclear fusion in stars involves the release of a small amount of energy

• Nuclear fusion is the process of breaking down heavy nuclei into lighter ones

• Two atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy.

• Stars are formed by the collision of two planets

What happens to a star during the red giant phase?

• It disappears completely.

• It shrinks and becomes smaller in size.

• It expands and becomes larger in size.

• It turns into a black hole.

What are the stages involved in the life cycle of a star?

• Nebula, protostar, main sequence, red giant or supergiant, and then either a white dwarf, neutron star, or black hole

• Morning, Afternoon, Evening, Night

• Seed, Sprout, Plant, Flower

• Sun, Moon, Earth, Mars

What is the role of gravity in the formation of a star?

• Gravity pulls together gas and dust to form a star.

• Gravity has no role in the formation of a star

• Gravity causes the gas and dust to explode

• Gravity pushes gas and dust away from each other

Explain the process of nuclear fusion in stars.

• Nuclear fusion in stars involves the combination of iron atoms to form heavier elements.

• Hydrogen atoms fuse to form helium at high temperatures and pressures in the core of stars.

• Stars are powered by nuclear fission, not fusion.

• Carbon atoms fuse to form oxygen at low temperatures and pressures in the core of stars.

What are the different ways in which a star can die?

• Black dwarf, neutron star, and comet

• Supernova, white dwarf, and black hole

• Supernova, red dwarf, and asteroid
