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. Topsoil - Subsoil - Parent rock - Bedrock






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






3. What does High Pressure usually indicate?






4. Caused by warm and cool air colliding






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






6. 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






7. 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






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






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






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






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






12. Where are there more extreme and low tides?






13. 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






14. Occur when the shadow of the Earth or Moon is cast onto the other body






15. Everything that surrounds a star (sun); its made up of numerous bodies which orbit the sun due to centrifugal force






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






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






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






19. Chunks of rocks and ice






20. 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






21. Water that goes into the ground






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






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






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






25. Huge clusters of billions of stars






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






27. Chemical breakdown of minerals






28. 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






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






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






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






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






33. Divergent - convergiant - and transform






34. Why does the moon have craters?






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






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






37. 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






38. Barometric Pressure






39. Barometer measures...






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






41. Chunks off rocks






42. What galaxy is Earth in?






43. Water soaks into the ground. Water collects on Earth's surface. Sometimes it runs off before collecting. The effect is lakes - ponds - oceans - rivers and streams






44. Movement of the moon around the Earth






45. 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






46. 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






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






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






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






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