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. What galaxy is Earth in?






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






4. What does High Pressure usually indicate?






5. 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






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






7. 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






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






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






10. Divergent - convergiant - and transform






11. 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






12. Topsoil - Subsoil - Parent rock - Bedrock






13. 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






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






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






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






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






19. Chunks of rocks and ice






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






21. Huge clusters of billions of stars






22. Barometric Pressure






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






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






25. Where are there more extreme and low tides?






26. 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






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






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






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






30. 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






31. Why does the moon have craters?






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






33. 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






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






35. What does Low Pressure usually indicate?






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






37. 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






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






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






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






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






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






43. 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






44. 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






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






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






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






48. Chunks of rocks that strike a planet






49. 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






50. A portion of the rigid crust that moves
