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. 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






2. A portion of the rigid crust that moves






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






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






5. Why does the moon have craters?






6. 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






7. Chunks of rocks that strike a planet






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






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






10. 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






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






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






13. 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






14. 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






15. 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






16. Divergent - convergiant - and transform






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






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






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






20. Chunks of rocks and ice






21. 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






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






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






24. 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






25. Huge clusters of billions of stars






26. Caused by warm and cool air colliding






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






28. Where are there more extreme and low tides?






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






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






31. What galaxy is Earth in?






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






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






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






35. Barometric Pressure






36. My very educated mama just served us nachos - Mercury - Venus - Earth - Mars - Jupiter - Saturn - Uranus - Neptune






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






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






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






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






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






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






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






44. 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






45. What does High Pressure usually indicate?






46. Movement of the moon around the Earth






47. What does Low Pressure usually indicate?






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






49. 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






50. 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
