Year 10 Cosmology Quiz

What is the origin of the universe according to the Big Bang theory?

• The universe always existed

• The universe was created by a deity

• The universe originated from a hot, dense state

• The universe formed from a massive explosion

How is the age of the universe estimated using the Big Bang theory?

• By measuring the distance to the farthest galaxy

• By analyzing the age of Earth

• By observing the rate of universal expansion

• By studying the brightness of stars

What evidence supports the Big Bang theory regarding the expansion of the universe?

• The observed cosmic microwave background radiation

• The existence of black holes

• The number of galaxies in the universe

• The size of the Milky Way

What did Edwin Hubble observe that provided evidence for the expansion of the universe?

• Gravitational waves

• Planetary orbits

• Redshift of distant galaxies

• Solar eclipses

How is the Doppler Effect (Red Shift) relevant to the Big Bang theory?

• It explains the existence of black holes

• It supports the idea of a static universe

• It indicates the universe is expanding

• It causes galaxies to move closer together

In the standard model of the universe, what is the first chemical element that formed after the Big Bang?

• Hydrogen

• Oxygen

• Iron

• Helium

How are stars, solar systems, and galaxies formed according to the standard model of the universe?

• Stars form from galaxies, and solar systems form from stars

• Galaxies form from solar systems, and stars form from galaxies

• Stars form from clouds of gas and dust, and galaxies form from collections of stars

• Solar systems form from the Big Bang explosion

What process occurs in the core of a star and is responsible for its energy production?

• Nuclear fission

• Nuclear decay

• Nuclear fusion

• Nuclear chain reactions

How does a star's mass impact the manner of its 'death'?

• More massive stars explode as supernovae, while less massive stars fade away

• More massive stars quietly turn into black holes, while less massive stars become white dwarfs

• All stars, regardless of mass, end their lives as black holes

• A star's mass has no impact on its 'death'

What is an emission spectrum?

• A pattern of light produced by a hot, thin gas

• A spectrum of colors seen during a solar eclipse

• A type of telescope used to observe galaxies

• A tool for measuring the age of stars
