SCIENCE THIRD QUARTER Questions and Answers
Combined from 2022-2023,solved for you.
What do you call the space rocks found mostly in the region between Mars and
Jupiter?
Asteroids
What do you call the icy rocks that travel from either the Kuiper Belt or from the
Oort Cloud?
Comet
What do you call the space rocks which are remnants of either an asteroid or a
comet?
Meteoroid
Which of the following statements describe the formation of meteors?
Meteoroids entered the atmosphere and burned up
What is the best explanation why asteroids failed to become planets?
The gravitational force of Jupiter is too high, preventing the space rocks from sticking
together
How does the ion tail of a coma form?
The ice portions of the comet melt as it moves nearer to the sun
How does the ion tail differ from the dust tail?
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?
to explain how the universe began
Why are meteorites easier to study than asteroids and comets?
Meteorites can be collected on Earth once they hit the ground
Choose which methods are used by scientists to determine the composition of
asteroids.
through collection of actual samples in space using space missions
through studying meteorites
Where do most short-period comets come from?
Kuiper Belt
Where do most long-term period comets come from?
Oort Cloud
Who among the following scientists accurately predicted the next arrival of a
certain comet?
Edmond Halley
How do comets from the Kuiper Belt reach the inner solar system?
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?
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?
, The tail streams out ahead of the nucleus
How are most well-known comets named?
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?
Using the gravitational theory of Newton
Why does the ion tail extend in a different direction when comets move in their
orbits?
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?
it has a tail
What do you call the swarms of meteors that are visible for a specific month in
the night sky?
meteor shower
How long do meteor showers usually last?
several days
few hours
Which of the following meteor showers occurs every December?
Geminids
How does a meteor shower occur?
when Earth passes through orbits of comets that have left a dust trail
What is the direction of meteors in a meteor shower?
going to the same direction
Will all meteors in a meteor shower hit the Earth's surface?
Not all meteors will hit the Earth's surface
Which of the following statements is true about meteor showers?
No meteor is known to have reached the ground
Geminids, Leonids, Andromedids, and Taurids are known annual meteor
showers. Which of the following meteor showers differ in terms of month of
occurrence?
Geminids
Which among the following comets is associated with a meteor shower every
November?
Comet Encke
Because you are amazed at the contributions of Edmond Halley, you planned to
see the remnants of Halley's comet. In which months will the meteor shower
associated with Halley's comet appear?
April and October
Which of the following refers to a large group of gas, dust, and millions of stars?
galaxy
Which of the following classifications of galaxies contains stars that are mostly
old?
elliptical galaxy
Which of the following galaxies has a random shape?
