What is the term for the movement of one object around another, such as Earth’s yearly path around the Sun?
Rotation
Revolution
Retrograde Motion
Gravity
Which object develops a glowing tail of gas and dust when it gets close to the Sun?
Asteroid
Comet
Meteor
Moon
What causes a meteor to appear as a streak of light in the sky?
It reflects sunlight
It burns up entering Earth’s atmosphere
It is a group of stars
It is a planet spinning
Which of the following best describes the difference between a comet and an asteroid?
Comets are rocky, asteroids are icy
Comets are icy and develop tails, asteroids are rocky and do not
Both are found in the asteroid belt
Asteroids orbit the Earth, comets orbit the Moon
If you observe a planet moving backward in the sky for a short period, what is this motion called?
Revolution
Retrograde Motion
Rotation
Gravity
Which planets in our solar system are classified as terrestrial planets?
Jupiter, Saturn, Uranus, Neptune
Mercury, Venus, Earth, Mars
Earth, Jupiter, Saturn, Mars
Venus, Neptune, Mars, Uranus
Why does Earth experience day and night?
Because of its revolution around the Sun
Because of its rotation on its axis
Because of gravity
Because of retrograde motion
Which of the following best explains why planets stay in orbit around the Sun?
The Sun’s gravity pulls them while their forward motion keeps them moving around it
The planets are attached to the Sun by invisible strings
The Sun pushes them away and they bounce back
The planets have their own gravity that repels the Sun
A student sees a bright streak in the night sky that quickly disappears. Based on your knowledge, what is the most likely explanation?
A planet is spinning
A meteor is burning up in Earth’s atmosphere
A comet is passing by
An asteroid is orbiting the Sun
Suppose you are asked to identify a planet as either terrestrial or Jovian. What characteristics would you look for, and why?
Only its color, because color determines type
Its size, composition (rocky or gas), and presence of rings or many moons, because these features distinguish terrestrial from Jovian planets
Its distance from the Sun only
Its speed of rotation only
Imagine you are observing the night sky and notice a group of stars forming a recognizable pattern. How would you determine if this is a constellation, and what steps would you take to identify it?
Ignore it, as patterns are random
Compare the pattern to known constellation charts and use star maps to match the arrangement
Ask a friend for their opinion only
Assume all patterns are constellations
A scientist wants to explain why retrograde motion occurs. What reasoning should they use based on the information provided?
Planets actually reverse their orbits
Retrograde motion is an apparent backward movement caused by differences in orbital speeds between Earth and other planets
The Sun causes planets to move backward
Gravity stops the planet temporarily
If you were to design a model of the solar system to show the difference between revolution and rotation, what features would you include and why?
Only show planets moving in circles
Show planets both spinning on their axes (rotation) and moving around the Sun (revolution) to illustrate both motions
Only show the Sun
Show planets with tails
