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. The tidal force produced by the sun is ____ as large as that produced by the moon






2. Affected by factors such as weathering and impurities






3. Volcanoes are also found in __________ - where the denser oceanic plates are forced under continental plates; this adds massive volumes of water to the mantle - allowing magma to melt more readily and rise to the surface to form volcanoes






4. 1 hour of time






5. 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






6. The sun is not at the center of the disk - but out toward the perimeter - and is revolving around the ________






7. The breakdown of rocks - soils and minerals through direct contact with atmospheric conditions such as heat - water - ice - and pressure






8. 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






9. Center: 3000

10. Common: wind - clouds - rain - snow - fog - dust storms - Less common: natural disasters such as tornadoes - hurricanes - and ice storms






11. Some isolated mountains were produced by volcanoes - including many apparently ________ that reach a great height above the ocean floor






12. Younger beds were originally deposited above older beds






13. Volcanoes can be caused by '____________'; these so - called hotspots - as in Hawaii - can occur far from plate boundaries






14. 4 terrestrials: Mercury - Venus - Mars - Earth 4 gas giants: Jupiter - Saturn - Uranus - Neptune At least 5 dwarf planets: Ceres - Pluto - Makemake - Haumea - Eris






15. A major determiner of coastal climate






16. The sun and oceans can also affect the weather of land - If the sun heats ocean waters for a period of time - water can evaporate - Once evaporated into the air - the moisture can spread over nearby land - thus making it cooler

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






18. Stars with the highest ___________ appear blue - while stars with the lowest surface temperature appear red






19. The science of the atmosphere and weather






20. Rising air currents take the vapor up into the atmopshere where cooler temperatures cause it to condense into ____






21. How much matter is in the object






22. The Pacific Ring of Fire has examples of volcanoes caused by ___________ coming together






23. 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






24. Large - dark clouds that indicate thunderstorms






25. 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






26. Can thaw and melt - and the ensuing water flows overland as snowmelt






27. Igneous rock that forms on the earth's surface - Examples obsidian - basalt - and pumice






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






29. Forms over land and is associated with dry air






30. Method of using the present to interpret the past - Processes occurring today are observed carefully and their effects are measured - Then - geologists assume that similar effects in ancient rocks were caused by processes similar to those of the pres






31. An opening - or rupture - in a planet's surface or crust - which allows hot molten rock - ash - and gases to escape from below the surface - Volcanic activity involving the extrusion of rock tends to form mountains or features like mountains over a p






32. On maps - the characteristics of an air mass are represented by two letters: The lowercase letter represents ________ - and the uppercase letter represents temperature






33. An area of frequent earthquakes and volcanic eruptions associated with the plate boundaries surrounding the Pacific Ocean - In a 40000 km horseshoe shape - associated with a nearly continuous series of oceanic trenches - volcanic arcs - and volcanic






34. 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.






35. 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






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






37. Occurs when the moon sets at sunset - Then the moon is between the earth and the sun - so we see only the dark half of the moon






38. Bbreaking along flat surfaces






39. Comprised of the crust and the rigid uppermost part of the mantle - broken up into tectonic plates (7 major and many minor) - ride on the asthenosphere






40. The breakdown of rocks - soils and minerals through atmospheric chemicals or biologically produced chemicals (also known as biological weathering)






41. The outermost part of the earth's interior is made up of two layers...






42. Continental polar (dry - cold air)

44. Forms over the Tropics and is warm






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






46. A semi - closed coastal body of water with one or more rivers or streams flowing into it - and with a free connection to the open sea - Often associated with high levels of biological diversity - They are made up of brackish water - Often given names






47. The cold - water current that flows north to south off the _____________ keeps the West Coast fairly cool during the summer - Cold - water currents create cooler temperatures in areas that would otherwise be much warmer
