TEST NAME: Science TEST ID: 1517366 GRADE: 06 - Sixth Grade SUBJECT: Social Sciences and History TEST CATEGORY: My Classroom Science Page 1 of 6 Student: Class: Date: 1. The table shows some of the characteristics of the soil in an area of land. Characteristics Surface Area Soil Color Soil Content Texture Flat Dark brown Humus, sand, and clay Gritty Which characteristic of this area indicates that the soil was formed as a result of the interaction between organisms and their environment? A. The area is flat. B. The soil color is dark brown. C. The soil contains humus. D. The soil feels gritty. 2. Which model best represents the internal structure of Earth? A. B. C. D. Science Page 2 of 6 3. The picture below shows the layers of Earth. When compared to the other layers of Earth, which layer has the lowest density? A. crust B. inner core C. mantle D. outer core 4. Which of these processes can cause layers of rock to be arranged so that the youngest layers are found below older layers? A. melting and hardening B. cooling and heating C. deposition and cementing D. uplifting and faulting 5. Lithospheric plates have moved to form land formations on the Earth's surface. Which land formation occurs as a result of the plates folding upon one another? A. an earthquake B. a mountain range C. a river D. a volcano 6. As two continental plates collide, the edges of the plates are crumpled and uplifted. Which of these landforms is most likely a result of this type of collision? A. normal faults B. mountain ranges C. U-shaped valleys D. shield volcanoes 7. When an earthquake wave passes from the crust to the mantle, the wave A. reverses direction. B. changes speed. C. increases energy. D. stops moving. Science Page 3 of 6 8. A glacier retreats leaving bare rocks. Lichens begin to live on the rocks. The lichens produce an acid that starts to break down the rocks. How will this process affect the environment? A. It will put acid into the lakes and ponds. B. It will begin the process of building soil. C. It will prevent the carbon cycle from occurring. D. It will prevent bacteria from invading the ecosystem. 9. Which of the following helped in the development of the theory of plate tectonics? A. measuring the depth of oceans near deep-sea trenches B. detecting magnetic striations on land once covered by glaciers C. understanding the ways organisms adapted to topographical changes D. understanding rock formations of a similar age occurring on two separate continents 10. Between 40 and 50 million years ago, the landmass on the Indian plate collided with the landmass on the Eurasian plate. What formed when these landmasses collided? A. the Grand Canyon B. the Great Plains C. the Himalayan Mountains D. the Mariana Trench 11. The islands in the mid-Pacific Ocean region were formed by A. land subsidence. B. deposition from currents. C. wind and water erosion. D. volcanic activity. 12. The movement of crustal plates results from circulating currents in material beneath the crust of Earth. Which best describes the material which moves the crustal plates? A. hot water B. molten rock C. liquid metal D. solid iron Science Page 4 of 6 13. This map illustrates part of the basin-and-ridge landscape of Nevada. This landscape resulted mainly from which phenomenon? A. glacial erosion B. wind erosion C. crustal folding and faulting D. sediment deposition in seas and oceans 14. What type of landform is most likely formed by a divergent tectonic plate boundary? A. island arc B. oceanic trench C. rift zone D. folded mountains 15. Which is a fact rather than an opinion about earthquakes? A. Earthquakes occur along fault lines. B. Earthquakes are worse than hurricanes. C. Earthquakes are bad for all local businesses. D. Earthquakes always cause major damage to homes. 16. Which of the following is a significant source of energy in the Earth’s interior? A. volcanoes B. convection C. molten rock D. radioactive isotopes Science Page 5 of 6 17. At which location does the movement of tectonic plates form isolated volcanic islands, such as Hawaii? A. transform boundary B. divergent boundary C. subduction zone D. hot spot 18. In the region where two continental plates collide, what geological feature most often forms? A. an ocean B. a volcano C. a river valley D. a mountain chain 19. Volcanoes are considered constructive because they A. deposit lava. B. cause erosion. C. trigger earthquakes. D. release gases. 20. Scientists have studied convergent boundaries and the results of the collisions. Besides the fact that mountains occur at these boundaries, which other part of the rock cycle is most likely associated with these areas of convergence? A. development of chemical rocks B. development of extrusive rocks C. development of layered rocks D. development of folded rocks Science Page 6 of 6
