Physics Quiz: Meteoroids, Asteroids, Comets, and HR Diagrams

What are the characteristics of meteoroids?

• Large icy bodies in outer space

• Gaseous bodies found in the Earth's atmosphere

• Tiny organisms living on the surface of planets

• Small rocky or metallic bodies in outer space

How are meteoroids different from asteroids and comets?

• Meteoroids are the remnants of supernovas, while asteroids and comets are not.

• Meteoroids are the same size as asteroids and comets, and they are made of different materials.

• Meteoroids are smaller than asteroids and comets, and they are the debris from asteroids or comets.

• Meteoroids are larger than asteroids and comets, and they come from the Earth's atmosphere.

Explain the differences between asteroids and comets.

• Asteroids and comets are both made of rock

• Asteroids are rocky bodies that orbit the sun, while comets are icy bodies that also orbit the sun but develop a visible coma and/or tail when close to the sun.

• Asteroids and comets both have tails when close to the sun

• Asteroids are made of ice and comets are made of rock

What is the Hertzsprung-Russell diagram and what does it show?

• It is a graph that shows the relationship between the absolute magnitude or luminosity of stars and their spectral type or surface temperature.

• It is a diagram that illustrates the formation of galaxies in the universe

• It is a chart that displays the movement of planets in the solar system

• It is a graph that shows the relationship between the distance of stars from Earth and their size

Where do main sequence stars appear on the HR diagram?

• On the bottom left corner

• On the diagonal band from the top left to the bottom right

• On the top right corner

• In the middle of the HR diagram

What is the significance of main sequence stars on the HR diagram?

• They have no significance on the HR diagram

• They are the smallest and least stable stars

• They are only found in galaxies outside of the Milky Way

• They represent the longest and most stable stage in a star's life cycle.

Describe the characteristics of meteoroids.

• Tiny organisms living on the surface of the moon

• Small rocky or metallic bodies in outer space

• Large icy bodies in outer space

• Gaseous bodies found in the Earth's atmosphere

Differentiate between meteoroids, asteroids, and comets.

• Meteoroids are small icy bodies, asteroids are large metallic bodies, and comets are rocky bodies.

• Meteoroids are large icy bodies, asteroids are small rocky bodies, and comets are metallic bodies.

• Meteoroids are large rocky bodies, asteroids are small icy bodies, and comets are metallic bodies.

• Meteoroids are small rocky or metallic bodies in outer space, asteroids are larger rocky bodies, and comets are icy bodies with a tail when near the sun.

Explain the purpose of the Hertzsprung-Russell diagram.

• To measure the distance between galaxies

• To study the behavior of black holes

• To track the movement of comets

• To show the relationship between the luminosity, temperature, and classification of stars.

Why are main sequence stars important on the HR diagram?

• They are only visible from certain parts of the world.

• They represent the longest stage in a star's life cycle.

• They are the smallest stars in the universe.

• They are not important on the HR diagram.
