Exam Questions and CORRECT Answers
What do you call the space rocks found mostly in the region between Mars and Jupiter? -
Correct Answer- Asteroids
What do you call the icy rocks that travel from either the Kuiper Belt or from the Oort Cloud?
- Correct Answer- Comet
What do you call the space rocks which are remnants of either an asteroid or a comet? -
Correct Answer- Meteoroid
Which of the following statements describe the formation of meteors? - Correct Answer-
Meteoroids entered the atmosphere and burned up
What is the best explanation why asteroids failed to become planets? - Correct Answer- The
gravitational force of Jupiter is too high, preventing the space rocks from sticking together
How does the ion tail of a coma form? - Correct Answer- The ice portions of the comet melt
as it moves nearer to the sun
How does the ion tail differ from the dust tail? - Correct Answer- The ion tail is made of
electrically charged gas, while the dust tail is made of small dust particles
Which of the following statements best explains the importance of studying comets and
asteroids? - Correct Answer- to explain how the universe began
Why are meteorites easier to study than asteroids and comets? - Correct Answer- Meteorites
can be collected on Earth once they hit the ground
Choose which methods are used by scientists to determine the composition of asteroids. -
Correct Answer- through collection of actual samples in space using space missions
,through studying meteorites
Where do most short-period comets come from? - Correct Answer- Kuiper Belt
Where do most long-term period comets come from? - Correct Answer- Oort Cloud
Who among the following scientists accurately predicted the next arrival of a certain comet? -
Correct Answer- Edmond Halley
How do comets from the Kuiper Belt reach the inner solar system? - Correct Answer- They
are influenced by the gravitational force of one of the Jovian planets.
Why do only a few comets from the Oort Cloud reach the inner solar system? - Correct
Answer- They are not confined to the plane of the solar system and move in all directions to
the sun
What happens when a comet passes close to the Sun? - Correct Answer- The tail streams out
ahead of the nucleus
How are most well-known comets named? - Correct Answer- They are named after the
discoverer
Edmond Halley was able to predict that a comet seen in 1683 would return in 1758. How did
Halley calculate the next arrival of this comet? - Correct Answer- Using the gravitational
theory of Newton
Why does the ion tail extend in a different direction when comets move in their orbits? -
Correct Answer- Ion tail extends as the solar winds pushed the melted particles at all points
from the sun.
You saw a moving object in the sky. Your friend told you that the moving object was a comet.
How could your friend prove that the moving object was a comet? - Correct Answer- it has a
tail

- Correct Answer- meteor shower
How long do meteor showers usually last? - Correct Answer- several days
few hours
Which of the following meteor showers occurs every December? - Correct Answer-
Geminids
How does a meteor shower occur? - Correct Answer- when Earth passes through orbits of
comets that have left a dust trail
What is the direction of meteors in a meteor shower? - Correct Answer- going to the same
direction
Will all meteors in a meteor shower hit the Earth's surface? - Correct Answer- Not all meteors
will hit the Earth's surface
Which of the following statements is true about meteor showers? - Correct Answer- No
meteor is known to have reached the ground

remnants of Halley's comet. In which months will the meteor shower associated with Halley's
comet appear? - Correct Answer- April and October
Which of the following refers to a large group of gas, dust, and millions of stars? - Correct
Answer- galaxy
