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






2. 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






3. Chunks off rocks






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






5. 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






6. 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






7. Where are there more extreme and low tides?






8. 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






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






10. What galaxy is Earth in?






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






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






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






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






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






16. Barometric Pressure






17. A portion of the rigid crust that moves






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






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






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






21. 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






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






23. 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






24. Chemical breakdown of minerals






25. Chunks of rocks and ice






26. 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






27. Water that goes into the ground






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






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






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






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






32. Movement of the moon around the Earth






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






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






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






36. 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






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






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






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






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






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






42. Divergent - convergiant - and transform






43. 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






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






45. Caused by warm and cool air colliding






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






47. What does High Pressure usually indicate?






48. 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






49. Raising and lowering of the water level






50. 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
