CSET Earth

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. (in descending order of size) the Pacific Ocean - the Atlantic Ocean - the Indian Ocean - the Southern Ocean and the Arctic Ocean






2. Due to a combination of differential heating and geometry - hen the sun rises - it is the tops of the mountain peaks which receive first light - and as the day progresses - the mountain slopes take on a greater heat load than the valleys - This resul






3. Traces of ancient life preserved in the strata as shells - footprints - and the like - Soft plant and animal tissues decompose quickly in the presence of decay bacteria - which exist wherever oxygen exists






4. One tidal cycle per day






5. Rocks are placed into groups according to how they form...






6. Result from the earth's axis being tilted to its orbital plane - NOT the result of the variation in the earth's distance to the sun (Because of its elliptical orbit - the earth as a whole is slightly warmer when away from the sun; this is because the






7. The process in which one type of rock changes into another






8. Composed of the fragments of other types of rocks - Cover 75 to 80% of the earth's land area - Often deposited in distinct parallel layers - Weather and erosion break down other rock types into sediments - Over time - the sediments become cemented an






9. Smooth layers of low clouds that indicate a chance of drizzle or snow






10. The variety of ways by which water moves across the land - This includes both surface runoff and channel runoff - As it flows - the water may percolate into the ground - evaporate into the air - become stored in lakes or reservoirs - or be extracted






11. Giant masses of solid rock that float upon the earth's mantle - These plates move in relation to one another at one of three types of plate boundaries...






12. Darkens the moon as the earth passes between it and the sun - casting a shadow on the moon - may be seen from anywhere the moon is visible - about half of the earth






13. Takes place when the moon passes between the earth and the sun - with the moon blocking the sunlight for about two minutes - A total ___________ may be seen only from a small zone on the earth






14. Solar Atmosphere is divided into the inner chromosphere with explosive prominences and the outer corona - a glowing halo visible only during a total eclipse - Constantly emitting particles as a...






15. Center: 3000

16. The source of energy for evaporation is primarily through ___________






17. Natural chemical compounds that are the crystals that make up rocks - Each has a specific composition or narrow range of composition






18. Cause pressure differences - A hot surface heats the air above it and the air expands - lowering the air pressure and its density






19. Sedimentary rocks containing large fragments of other rock material - e.g. Sandstone






20. Improved land - use practices can limit erosion by using techniques such as...






21. When the moon is at first quarter or third quarter - the sun - earth and moon form a 90- degree (right) angle with the earth at the vertex - The combined effect of this alignment of the sun - earth - and moon results in tidal ranges on the earth - Wh






22. Test the item against materials of known hardness; for example - use your fingernail or the graphite in a pencil to attempt to scratch the items. This process should result in assigning a relative hardness to the unknown items.






23. Maritime polar (wet - cold air)






24. Scientists theorize that massive volcanic eruptions on a global scale contributed to the earth's cooling - resulting in the onset of the...






25. Thought to originate in the Kuiper Belt - or associated scattered discs - which lie beyond the orbit of Neptune






26. Tends to move slowly and is replenished slowly - and so it can remain in aquifers for thousands of years






27. The tendency of a moving object to stay in a straight line or a stationary object to remain in place - Without _______ - a planet would be pulled into the sun






28. A huge ball of incandescent gases - Its mass is more than 300000 times that of the earth - Principal constituents are the lightest elements - hydrogen and helium






29. The degrees east or west of the prime meridian through Greenwich - England






30. The lateral movement of the plates is typically at speeds of ___ mm annually






31. The best determiner of climate - as it is consistently and directly correlated with temperature - other factors: Rain shadows - as well as water currents - elevation and so forth






32. Erosion in many places is increased by human land use - Poor land - use practices include deforestation - overgrazing - unmanaged construction activity - and road building






33. Bodies similar to the sun but immensely distant - Closest stars are 4 light - years away






34. The difference between levels of ocean water at high and low tides






35. Not all runoff flows into rivers; much of it infiltrates into the ground through...






36. Younger beds were originally deposited above older beds






37. Gas giants Jupiter - Saturn - Uranus and Neptune have diameters far larger than Earth's and have far greater masses






38. (or summer time zones) include an offset (typically +1 hour) for daylight saving time






39. A natural flow of water - usually freshwater - traveling toward an ocean - a lake - or another stream






40. Further caused by the elliptical orbit of the earth - Earth reaches perihelion (the point in its orbit closest to the sun) in January - and it reaches aphelion (farthest point from the sun) in July - Also depend on factors such as proximity to oceans






41. Almost all familiar weather phenomena occur in the __________ (the lower part of the atmosphere)
