• Arrows 2 and 3 
• Arrows 1 and 2 
• Arrows 1 and 3 
• Arrows 3 and 4 

Day 6 - Q3:  
 
The tilting of the Earth on its axis contributes to: 

• the different phases of the moon we see 
• the changing of seasons as Earth moves around the Sun 
• high and low ocean tides
  
• an increase in the gravitational force from the Sun 

Day 6 - Q4:

What season will it be? 

• winter 
• spring

• A
• B
• C
• D

Day 6 - Q6:

• A
• B
• C
• D

Day 6 - Q8: 
 
Which of the following characteristics do the Earth and Moon closely share in common? 

• makeup of the atmosphere 
• amount of gravitational force 
• approximate distance from the Sun 
• volume of water on the surface 

Day 6 - Q9: 
 
Astronauts who walked on the Moon were able to “jump” two to three times higher than they were able to on Earth. This is primarily due to: 

• The lunar atmosphere is much less dense. 
• The Moon is much less massive than the Earth. 
• Special suits engineered by NASA made the astronauts more mobile. 
• Astronauts trained their muscles for the unique lunar surface. 

Day 6 - Q10: 
 
In August 1981, Voyager II approached the planet Saturn. During this time, it’s speed increased from 17 km/s to 34 km/s. Why did this sudden increase in speed occur? 

• Saturn has a magnetic field which attracted the probe. 
• Onboard rockets must have been fired.
  
• The solar winds are very strong near Saturn. 
• The gravitational pull of Saturn increased as the probe got closer to the planet.
