FORMATIVE MINI ASSESSMENTS Third Grading Period 2010-11 March 21-24 STUDENT NAME _____________________________________________ DATE _____________ PERIOD______ Science – Grade 6 Read each question and choose the best answer. Be sure to mark all of your answers. Crust Mantle Composition of Earth's Crust Core © Edusoft 1 The model of Earth shown above would be more accurate if — A the Earth's crust was much thinner than the mantle B the Earth's mantle had a different shape C the order from inside to outside was mantle, core, crust 3 Element Percentage of Earth's Crust Oxygen 46.6% Silicon 27.7% Aluminum 8.1% All other elements 17.6% As part of a science lab report, a student made a table, like the one shown above, to organize data about the Earth's crust. Based on the data above, which of the following statements is a valid conclusion? More than 50% of the Earth’s crust is made of — D the core had a more egg shaped form A elements other than oxygen, silicon, and aluminum B just the element of oxygen C oxygen and silicon D other elements plus silicon 2 Igneous rock can be turned into sedimentary rock through which of the following processes? F Weathering, compacting and cementing G Melting and dissolving H Heat, pressure, and solidifying J © SAISD Cooling and hardening 06 Science FMA March 11 Page 1 Solar flares Planets in Order Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Solar cloud Sunspot Corona 4 A student made the drawing shown above to show some characteristics of the Sun. Which of the following represents a cooler area on the surface of the sun? 6 What can you infer from the data in the chart above? F The temperature of a planet depends on its size. F Solar flare G The farther the planet is from the Sun the lower its temperature. G Sunspot H Solar cloud J H The temperature of a planet depends on its composition. Sun's corona J 5 A revolution is when Earth completes one complete trip around the — A Asteroid B Moon C Comet D Sun Average Temperature (oC) 427 453 56 -63 -153 -185 -214 -225 7 The faster a planet rotates the higher its temperature will be. Which of the following describes the role of gravity between the sun and planets? A Gravity allows the planets to fly out into space. B Gravity holds the planets in orbit around the sun. C Gravity only holds the inner planets in their orbit. D Gravity has no influence on the planets’ orbits. © SAISD 06 Science FMA March 11 Page 2 Mohs Scale of Mineral Hardness Hardness 1 2 3 4 5 6 7 8 9 10 8 10 Both gypsum and limestone are found in the quarry. Limestone has about the same hardness as calcite. A mineral’s hardness can be determined from how easily it is scratched by another mineral. In a hardness test, what result will show the difference between gypsum and limestone? The space shuttle was the first — F moon lander G disposable rocket H artificial satellite J Mineral Talc Gypsum Calcite Fluorite Apatite Orthoclase Quartz Topaz Corundum Diamond reusable space vehicle F Fluorite scratches limestone and gypsum. G Limestone scratches talc. H Calcite scratches gypsum. J 9 The space suit is an important piece of equipment for an astronaut. All of the following are functions of the space suit except — A supplying oxygen for the astronaut to breathe Gypsum scratches talc. 11 Artificial satellites are used to do all of the following except — A send and receive signals B offering protection from the sun's radiation B send astronauts into space C observing the conditions on the inside of the shuttle C explore the solar system D conduct scientific research D allowing the astronaut to talk with others © SAISD 06 Science FMA March 11 Page 3 Rock Cycle Igneous rock Solidification Weathering and erosion Magma or Lava Melting Metamorphic rock Sediments Deposition Burial, compacting, and cementing Metamorphism Sedimentary rock Heat and/or pressure 12 Which two processes result in the formation of metamorphic rocks? F Heat and pressure G Weathering and erosion H Burial and cementation J Melting and solidification Outer Planets A B Inner Planets C 13 Which of these statements belongs in section B in the above Venn diagram? A Solid, rocky surfaces B Solid and/or liquid water C Produces heat and light D Held in orbit by Sun’s gravity © SAISD 06 Science FMA March 11 Page 4 14 Which diagram best represents the type of plate movement that results in mountain building? F H G J 15 The transform-fault boundary where the North American and Pacific plates are moving past each other results in — 16 Which physical property would be most helpful to a student trying to identify an unknown mineral? A ocean basins F Mass of the mineral B earthquakes G Shape and texture C volcanic eruptions H Hardness and streak D mountains J © SAISD 06 Science FMA March 11 Color and size Page 5 Use the map and your knowledge of science to answer questions 17-18. Eurasian Plate North American Plate Juan de Fuca Plate Philippine Plate Caribbean Plate B D Cocos Plate C Nazca Plate A Arabian Plate Antarctic Plate Antarctic Plate Plate Movement Plate Boundaries 17 According to the map above, what is the name of the major tectonic plate identified by the letter “B”? 18 Between North American Plate and Eurasian Plate, there is a _____________ boundary, which results in _______________. A Indo-Australian Plate F convergent; volcanic mountains B Pacific Plate G convergent; island arch C South American Plate H divergent; rift valley D African Plate J © SAISD 06 Science FMA March 11 divergent; mid-ocean ridge Page 6 19 In which diagram are the layers of Earth correctly labeled? Crust Crust C A Top to Center: Lithosphere, Asthenosphere, & Mesosphere Top to Center: Mesosphere, Lithosphere, & Asthenosphere Inner core Outer core Not Drawn to Scale Not Drawn to Scale Inner Core Crust Crust D B Top to Center: Lithosphere, Asthenosphere, & Mesosphere Top to Center: Mesosphere, Lithosphere, & Asthenosphere Inner core Outer core Not Drawn to Scale © SAISD Outer core Inner core 06 Science FMA March 11 Not Drawn to Scale Outer Core Page 7 Crust (50 km) Lithosphere (150 km) Mantle Asthenosphere (250 km) (2,800 km) Core (3,428 km) Mesosphere (2,550 km) Outer core (2, 200 km) Inner Core (1, 228 km) 20 Imagine that you can travel to the center of the Earth. The diagram above lists the average thickness of each layer of the Earth. How far from the center of the Earth would you be if you were leaving the lithosphere and entering the asthenosphere in kilometers? Record and bubble your answer. © SAISD 06 Science FMA March 11 Page 8
