5. Which statement about unbalanced forces is correct?
Unbalanced forces change how and where an object moves.
Unbalanced forces always have a net force less than zero.
Unbalanced forces are always caused by friction and gravity.

Northeast
Northwest
Southwest
Southeast

7. The relative positions of Earth, the Moon, and the Sun determine the Moon and Sun’s gravitational pull on the planet. For this reason, during which phases of the Moon do the lowest tides (neap tides) occur?
First quarter and last quarter
Full moon and new moon

8. Earth completes one rotation on its axis about every 24 hours
Earth completes one rotation on its axis about every 24 hours. What would be the most likely result if Earth completed one rotation on its axis every 12 hours?
Earth would cycle through the four seasons more quickly.
Some places on Earth would experience fewer hours of daylight.
Earth would cycle through periods of daylight and darkness more quickly.
Some places on Earth would experience fewer hours of darkness.

9. Based on the diagram shown above and what you know about food webs, which of the following conclusions is correct?
Since organisms withing a food web have several food choices, all the organisms within the food web can survive.
Since organisms within a food web are interdependent, the disappearance of one organism within the food web could affect all the organisms within that web.
Since both producers and consumers live within a food web, the energy available within the food web remains constant.
Since organisms within a food web must compete for food, the disappearance of one organism within the food web helps other organisms within the web to survive.

10. In science class, students were asked to complete a food web like the one shown below In which numbered box on the food web should students place autotrophs?
Box 1
Box 2
Box 3
Box 4

11. The thrust from a rocket’s engine lifts the rocket into the air
The thrust from a rocket’s engine lifts the rocket into the air. Which of the following best explains why the engine’s thrust lifts the rocket?
An object in motion tends to stay in motion; an object at rest tends to stay at rest.
The greater an object’s mass, the greater its resistance to a change in motion.
For every action, there is an equal but opposite reaction.
The greater the force applied to an object, the greater the object’s acceleration.
