Answers
1
What is the Moon's orbit shape?
Spiraled path
Perfectly circular
Randomly shaped
Highly elliptical
2
True or false: The Sun is the only source of energy for life.
True
False
3
How does the Moon reflect sunlight?
Reflects sunlight only
Absorbs and emits light
Generates its own light
Changes color with light
4
What happens during a lunar eclipse?
Moon blocks Sun
Sun blocks Moon's light
Earth blocks Sun's light
Moon disappears completely
5
Why does one side of the Moon face Earth?
Moon doesn't rotate
Sun's pull keeps it still
Synchronous rotation occurs
Orbit too slow to notice
6
What causes the Moon's shape changes?
Moon changes size
Sun's brightness varies
Position relative to Sun
Earth's rotation colors it
7
What pattern do astronauts see on the Moon?
Cycle of Moon phases
Sun's rotation affects light
Earth's pull changing orbit
Moon around the Sun
8
True or false: The Moon changes size as it orbits Earth.
True
False
9
Why do objects in space have predictable orbits?
Gravity keeps them stable
Sun's heat creates wind
Size determines orbit
Space is frictionless
10
What makes the Sun important?
Controls Moon's motion
Provides gravity for orbit
Largest object in system
Only light source
11
What if the Moon's orbit was highly elliptical?
Moon won't reflect light
Orbit becomes more stable
Speed and distance vary
Moon appears same size
12
Why are models of the Earth-Moon-Sun system useful?
Travel through space
Visualize object relationships
Exact life-sized models
Replace observations with math
13
How does Moon illumination help scientists?
Moon glows from within
Visible only at night
Creates shadows for features
Uses artificial lights
14
What does synchronous rotation mean?
Fast rotation
Irregular rotation
No rotation at all
Same rate as orbit
15
What is the main reason for tides?
Moon's gravitational pull
Wind patterns
Earth's rotation
Sun's gravitational pull
16
True or false: Models can replace real-world observations.
False
True
17
What if the Sun stopped emitting light?
New Moon phases occur
Partially visible from Earth
Moon disappears completely
Moon appears the same
18
How does scale help in solar system models?
Represents distances accurately
Human eye observes correctly
Changes physics laws
Arranges bodies randomly
