CSET Multiple Subject: Earth Science

Subjects : cset, science
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. All the Earth's continents at one time were joined as a single 'super continent' called Pangaea Over time the continents drifted apart






2. What does High Pressure usually indicate?






3. A portion of the rigid crust that moves






4. Are caused by the gravitational pull of the moon and the sun on Earth; moon has greater effect on the tides because its closer than the sun






5. Carbonization (carbon dioxide) - Hydration - Oxidation (rust)






6. Water enters cracks of rocks - water freezes and expands - causing rocks to break into pieces.






7. Two plates are moving away from each other (Mid - Oceanic Ridge)






8. What causes our solar system to orbit the sun?






9. Gas becomes a liquid vapor rises into air and cools. Water vapor (gas) changes into liquid water (clouds)






10. Spiral disk with several long arms; Earth is in one of the arms






11. Are based on the moon's revolution around the Earth






12. Why does the moon have craters?






13. Movement of the moon around the Earth






14. Based on the Earth's revolution around the sun






15. Where are there more extreme and low tides?






16. Is one that can be reused - regrown - recycled - or is not consumed with use. These are resources that can be conserved. ex. solar energy - hydroelectric and wind power - and geothermal energy






17. Igneous (burning molten rock magma turns to lava when it reaches the surface - hardens very quickly causing imperfections) ex. granite - Metamorphic (baked by pressure underground) ex. diamond (pure) - Sedimentary - ex. sand - sandstone






18. From fire (ignite) the formation of igneous rocks occurs when hot molten rock cools or solidifies. Igneous rock can be produced deep in the Earth from magma or on the surface of the Earth from lava






19. Two plates colliding. One plate moves under the other plate - usually producing mountains






20. By the Hertzsprung - Russell Diagram. The HRD illustrates the relationship between the absolute magnitude - luminosity - classification - and effective temp. of stars






21. Caused by warm and cool air colliding






22. Raising and lowering of the water level






23. Area of volcanoes surrounding the Pacific plate. The subduction plate movement causes the production of volcanoes. Westcoast of the US and the East Coast of Asia






24. Transforms into an adult star - as the star converts its fuel into more massive elements and compounds - it becomes denser






25. Sea - floor spreading - the 'puzzle piece' argument and fossil records






26. The convection current is produced by the heating of the mantle rock - as the rock is heated it moves up toward the lithosphere where it cools and begins to be pulled back toward the center of the Earth by gravity






27. The moon and sun are on opposite sides of the Earth. The Earth blocks the sun casting its shadow on the moon; there's no light on the moon






28. When the moon and sun are pulling at perpendicular angles; less extreme tides






29. Compression of biological matter (dead organic matter) - beneath layers of sedimentary rock; hydrocarbon compound such as coal - natural gas - or petroleum






30. As a nebula contracts - the particles collide with colossal force - igniting a nuclear reaction and forming a protostar






31. Refers to the amount of dissolved salt in the ocean. salinity level is lower at the mouth of a river due to the flow of fresh water into the saltwater. Areas with high temp. (equator) or low temp. areas (Arctic and Antarctic Oceans) salinity is highe






32. What galaxy is Earth in?






33. Barometric Pressure






34. Divergent - convergiant - and transform






35. Based on its mass and other factors it will become either a brown dwarf - white dwarf - neutron star - nova - or a black hole






36. Warm water rises and leaves a low pressure - causing...






37. Chunks of rocks that strike a planet






38. Begin as huge clouds of dust and other particles; they form from the gravitational collapse of a diffuse interstellar cloud






39. Chemical breakdown of minerals






40. There are similarities of living species and identified fossils found in the continents of today that are the same. Reptiles in South America and Africa. Fossils of the same plants in India and Australia. Unique variety of garden snail found in easte






41. Magma cools to produce igneous rock which can undergo more heat and pressure to become metamorphic rock - On the surface of the Earth - igneous rock which undergos weathering can become sedimentary rock. Sedimentary rock can be buried which can cause






42. Are caused by the Earth's tilt on its axis. As it revolves around the sun - the tilt causes each hemisphere to receive more direct exposure at certain times in its orbit






43. Inner Core (solid metal - nickel - and iron) - Outer Core (liquid metal - magnetic force) - Mantle (rock) - Crust (thin layer)






44. Created by the wind - which stirs the ocean's surface over greater distances






45. Huge clusters of billions of stars






46. A nonstop movement of water between Earth's surface and the air






47. Water that goes into the ground






48. The Moon is between the Earth and the sun; The moon blocks light from the sun so the sun doesn't reach Earth






49. Barometer measures...






50. Water falling to the Earth; cloud droplets become to heavy. They fall - the effect is percipitation (rain - snow - sleet - hail)
