Grade 7th rock cycle test

  1. 1. AL-HUDA SCHOOL Campus III (Boys Section) Class Test 2013 ScienceRock and Weathering Grade VIIName: _________________________________Date:____________Time: 30 minutes Max. Marks: _________Parent signature: ____________________________Directions: Fill in the blank with the correct word. A list of possible answers is provided at thebottom of the page.1. _________ is made of one or more minerals.2. The three main groups of rocks are sedimentary, _____________, and igneousRocks.3. Sedimentary rocks are commonly made of __________ that are compacted andCemented together.4. ____________ involves the breaking down of rocks on the earth’s surface.5. ____________ rock solidifies to form igneous rocks.6. ____________ involves the transporting of sediment from one place toAnother.7. The rock ___________ illustrates how rocks change from one type of rock toAnother.8. The particles resulting from weathering of rocks may lead to theFormation of _______________ rock.9. Molten rock inside the earth is called ____________.10. Heat and __________ are key factors in the formation of metamorphic rocks.Metamorphic cycle molten erosion igneous pressureRocks sedimentary weathering lava magmaSedimentsDirections: Decide whether the answer is True (T) or False (F).11. Igneous rocks are only found within the earth.12. Molten rock found on the surface of the earth is called coral.13. Molten rock is only found close to the surface.14. Compaction and cementation of sediments are key processes involved in the formation ofsedimentary rocks.15. The process of rain wearing down rocks is an example of weathering.16. Moving water is a minor force in transporting sediment.17. Sand once existed as rock.18. The rock cycle only flows in one direction.19. Magma is the result of rocks being heated into liquid rock.20. Erosion is responsible for transporting sediment.
