Take The Practice Questions Test On Astronomy! Quiz - Quiz

How much do you know about astronomy? Some people may not understand the importance of comprehending astronomy. It offers a way to establish planets other than Earth. It also helps to deter any damage that might arise because of a cosmic impact. Astronomers derive considerable skills in math, physics, science, and critical thinking. This out-of-world quiz will assist you in learning about astronomy.

2.

How do the size and mass of Jupiter's core compare to the size and mass of Earth?
- A.
  
  It is the same size and mass.
- B.
  
  It is about 10 times larger both in size and mass.
- C.
  
  It is about 10 times larger in size and the same mass.
- D.
  
  It is about the same size but is 10 times more massive.
- E.
  
  Jupiter doesn't have a core—it is made entirely from hydrogen and helium.
3.

Why is Jupiter denser than Saturn?
- A.
  
  It is made of a different composition than Saturn, including a higher proportion of hydrogen compounds and rocks.
- B.
  
  The extra mass of Jupiter compresses its interior to a greater extent than that of Saturn.
- C.
  
  Its core is much larger than Saturn's.
- D.
  
  It has a greater proportion of helium to hydrogen compared to Saturn.
- E.
  
  Scientists do not know why this is so.
4.

Why is Saturn almost as big as Jupiter, despite its smaller mass?
- A.
  
  Jupiter's greater mass compresses it more, thus increasing its density.
- B.
  
  Saturn's rings make the planet look bigger.
- C.
  
  Saturn is further from the Sun, thus cooler, and therefore less compact.
- D.
  
  Saturn has a larger proportion of hydrogen and helium than Jupiter, and is therefore less dense.
- E.
  
  Jupiter's strong magnetic field constrains its size.
5.

How do the jovian planet interiors differ?
- A.
  
  All have cores of about the same mass, but differ in the amount of surrounding hydrogen and helium.
- B.
  
  The core mass decreases with the mass of the planet.
- C.
  
  The composition changes from mostly ammonia in Jupiter and Saturn to mostly methane in Uranus and Neptune.
- D.
  
  The composition changes from mostly hydrogen in Jupiter and Saturn to mostly helium in Uranus and Neptune.
- E.
  
  All have about the same amount of hydrogen and helium but the proportion of rocks is greater in those planets closer to the Sun.
6.

Why are there no impact craters on the surface of Io?
- A.
  
  It is too small to have been bombarded by planetesimals in the early solar system.
- B.
  
  Jupiter's strong gravity attracted the planetesimals more strongly than Io and thus none landed on its surface.
- C.
  
  Io did have impact craters but they have all been buried in lava flows.
- D.
  
  Any craters that existed have been eroded through the strong winds on Io's surface.
- E.
  
  Io's thick atmosphere obscures the view of the craters.
7.

What mechanism is most responsible for generating the internal heat of Io that drives the volcanic activity?
- A.
  
  Accretion
- B.
  
  Radioactive decay
- C.
  
  Differentiation
- D.
  
  Tidal heating
- E.
  
  Bombardment
8.

- B.
  
  Nitrogen
- C.
  
  Hydrogen compounds
- D.
  
  Oxygen
- E.
  
  Argon
9.

- D.
  
  Its surface is hidden from view by its thick atmosphere.
- E.
  
  It is the coldest moon in the solar system.
