Day 6 - Science STAAR Review

Which arrow indicates the cause of day and night on Earth? 

• Arrow 1
  
• Arrow 3
  
• Arrow 4
  
• Both Arrow 1 & 4 

Which arrows show the revolution of a body in space? 

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

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 

Katrina travels to Australia when the Earth is located at Arrow #1 and it is winter. She returns to Australia when the Earth is located at Arrow #4. What season will it be? 

• winter 
• spring 
• summer 
• autumn 

 Sarah observes and records these moon phases. 
Which phase will she observe on Night 15? 

• A
• B
• C
• D

When will we see a full moon rise above the eastern horizon? 

• around 2 AM in the morning 
• about the time of sunrise 
• middle of the day
  
• about the time of sunset 

What phase of the moon will you see in this situation? 

• A
• B
• C
• D

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 

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. 

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.
