1 PSSA Questions 6th Grade

2 Water Cycle Which statement correctly describes a water cycle process?
Evaporation can occur when the water gains energy from the Sun and changes into water vapor. Condensation can occur when liquid water molecules in clouds lose energy and fall to Earth. Transpiration can occur when atmospheric water vapor gains energy and moves higher in the atmosphere. Precipitation can occur when atmospheric water vapor loses energy and forms liquid water droplets. A

10 Planetary Orbit The force that causes Earth to orbit the Sun is due to: A. Magnetism B. Gravity C. Solar wind D. Gamma radiation B

11 Systems Which of these is an example of a closed-loop system? A. The flow of energy from a power plant to your home. B. A food web. C. An electrical circuit with an open switch. D. Carbon material in the Carbon cycle. A

12 Earth’s Surface Which activity changes Earth’s surface in the shortest amount of time? A. A river creates a valley through erosion. B. A mountain is created through tectonic forces. C. Wind forces shape a column of desert rock. D. A volcanic eruption turns a mountain into a level plain. D

13 Earth’s Surface Most of the energy that is used on the Earth, or causes change, comes from: A. Water B. Tectonic activity C. The Sun D. Nuclear fission C

14 Fossils A group of scientists excavates an area in southern Pennsylvania. About 10 meters down, they discover fossils of ancient marine mammals. What can the scientists conclude from this finding? A. This area of Pennsylvania was hit by a large tidal wave at one point. B. Undersea terrain has moved beneath the crust from the ocean to Pennsylvania. C. Ancient marine mammals had the ability to move about on land from the oceans to Pennsylvania. D. Parts of Pennsylvania were once underwater. D

15 Solar System What is the difference between a moon and a planet? A. A moon does not have a rotation, a planet does. B. A moon does not directly orbit the Sun, a planet does. C. A planet is large, a moon is small. D. A planet is made of gas, a moon is made of rock. B

16 Scientific Method Which of the following can result after a hypothesis has been tested many times, producing the same result? A. A variable B. A theory C. A control D. A graph B

17 Scientific Method A food worker hypothesizes that the colder the refrigerator is, the longer milk and other perishable foods will last without spoiling. If she were to set up an experiment with multiple refrigerators, which variable would she change between them? A. Temperature B. Time C. Contents D. Size A

18 Scientific Method Beth uses 2 brands of window cleaner, Method and Windex, to clean her living room window. She divides the window into sections and counts the number of strokes it takes to clean each section with each cleaner. Method took 10 strokes. Windex took 15 strokes. Which question was Beth most likely testing? A. Which window cleaner cleans fastest? B. Which window cleaner leaves the fewest smudges? C. How do window cleaner ingredients compare? D. Which window cleaner smells better? A

19 Rock Cycle Which statement about the rock cycle is true? A. The rock cycle is an open-loop system. B. The rock cycles loses sedimentary material through weathering. C. The rock cycle is continuously recycling. D. The rock cycle creates sediments through heat and pressure. C

20 Solar System Explain what causes the phases of the Moon. A

21 Rock Cycle What kind of information does a diagram of a rock cycle show? A. Where certain types of rocks are found B. A comparison of the hardness of different types of rocks C. When the rocks were first discovered D. How different rocks are formed D

22 Earth’s Movement What kind of information do scientists obtain from a tectonic plate map? A. The size and motion of the Earth’s oceans B. The location of earthquakes and volcanic activity C. The weather activity of regions D. The boundaries of different ecosystems B

23 Scientific Method During the experiment, MaryBeth observed that water droplets formed on the plastic wrap that she had wrapped around a glass of water. Where did the water droplets come from? A. The cup was leaking B. The plastic wrap C. The water inside D. A reaction between sunlight and the plastic wrap C

24 Resources A renewable natural resource used by people is: A. Crude oil B. Natural gas C. Wood D. Coal C

25 Minerals Describe the transformation process involved in making a gold ring. Alloys, mining, refining, slag/pollution, polishing, smelting, selling/packaging that involves energy resources: Example response: In order to make the ring, gold, silver, and copper must be mined. Mining takes energy and damages the environment. Refining of the metal ores requires energy and produces pollution. Packaging and shipping consumes resources and creates pollution.

26 Rock On Various mining techniques are used to mine different materials. Surface mining, aka strip mining, is used when the desired materials are close to the surface. Which is the least significant impact resulting from strip mining? A. Erosion B. Pollution of nearby streams and rivers C. Habitat destruction D. Air pollution D

27 Environment Conservation
Suggest ways to minimize the environmental impact of a new housing development. Example response: Use green building materials (recycled materials, renewable energy resources for heating and cooling), reuse of space, orientation of housing, layout and size of house

28 Water Cycle Which statement is the most complete description of the Earth’s water cycle? A. The water cycle has no beginning and no end. B. The water moves among the oceans, atmosphere, and land masses in a continuous manner. C. Energy from the Sun causes the evaporation of water from Earth’s oceans. D. Condensation and precipitation are part of a never-ending cycle. B
