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






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






3. Why does the moon have craters?






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






5. Chunks of rocks and ice






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






7. 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






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






9. Raising and lowering of the water level






10. Barometric Pressure






11. Water that goes into the ground






12. A portion of the rigid crust that moves






13. 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






14. 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






15. Highs want to equalize which causes high winds - causing...






16. 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






17. Movement of the moon around the Earth






18. Chemical breakdown of minerals






19. Two plates sliding past each other; up and down and back and forth (San Andrea's Fault) transform faults occur where plates do not move under or away from each other






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






21. 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






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






23. Arctic Air pushes down causing colder water (Pacific Coast) - Tropical Air comes up from the Gulf stream causing warmer water (Coast of Florida)






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






25. All the Earth's continents at one time were joined as a single 'super continent' called Pangaea Over time the continents drifted apart






26. Huge clusters of billions of stars






27. Chunks of rocks that strike a planet






28. Topsoil - Subsoil - Parent rock - Bedrock






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






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






31. 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






32. When the moon and sun are in alignment; both working to pull on Earth; extreme tides






33. Refers to the vast periods of time over which the Earth changes






34. Occurs when an older oceanic plate is pushed unmder a younger oceanic plate. The shifting plates can cause earthquakes - volcanoes - and mountains






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






36. As plates move - strain is placed on the lithosphere. Due to the ridgity of the lithosphere - stress is built up until rocks move or brak - producing a fault. As the rocks break - energy is released in the form of waves. These waves move through the






37. Liquid changes to a gas; caused bysun heating up bodies of water. The liquid water becomes vapor (gas)






38. Chemical means (acid rain) or physical means (wind - rain - and ice






39. 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






40. Divergent - convergiant - and transform






41. Changed in form; the rock changes occur due to extreme heat and pressure






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






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






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






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






46. What galaxy is Earth in?






47. Chunks off rocks






48. 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






49. Days are based on the Earth's rotation on its axis






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