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






2. Maritime tropical (wet - warm air)






3. A land form that stretches above the surrounding land in a limited area - with a peak - Usually produced by the movement of lithospheric plates






4. Characterized by similar temperatures and moisture levels






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






6. Featherlike clouds that indicate fair weather






7. The degrees north or south of the equator






8. Largest zone of the planet (68%); crystalline silicates - rich in magnesium - calcium - and iron; very hot and mainly solid - but local melting to magma is the source of volcanic eruptions






9. 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






10. Both gravity and inertia work together to keep planets in orbit around the sun - Inertia makes a planet travel in a straight line






11. There are approx. _____ days between each lunar cycle






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. Officially defined as sustained sea surface temperature anomalies of magnitude greater than 0.5






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






15. Distance to closest stars can be calculated by measuring the _________ - a slight shift in apparent position against the background of more distant stars as the earth travels around the sun






16. Occur when two plates slip past each other - Such faults are generally moderate and are relatively shallow Example: The San Andreas Fault






17. Hotspot volcanoes are also found elsewhere in the Solar System - especially on...






18. Forms over the Tropics and is warm






19. Most sediments were deposited in beds that were originally horizontal - and any tilting is due to later earth movements






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






21. An individual weighing 200 lbs on Earth would weigh more on a _______________ - Weight is a function of gravity






22. The runoff produced by melting snow






23. Seas - gulfs - bays - and other names






24. Younger beds were originally deposited above older beds






25. 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






26. Travels around the earth each month - - Distance from the earth averages 237000 miles - Has rugged topography formed billions of years ago by volcanic eruptions and meteorite impacts - Mass is 1/6th that of Earth






27. 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






28. A continuous drill would find gas - oil - and water in that order - The three substances occur in their order of density - with the lightest substance on top and the heaviest on the bottom






29. Human civilization has lasted only _____ years






30. Formed by sodium chloride






31. Forms south of the Arctic and is cold






32. Nearest galaxy - about 20 million light - years away






33. Formed from calcium carbonate - also an example of chemical sedimentary rocks - like roock salt - can contain organic or once - living matter and can record the history of that matter's formation in features such as strata - fossil evidence - and rip






34. One tidal cycle per day






35. 4 terrestrials: Mercury - Venus - Mars - Earth 4 gas giants: Jupiter - Saturn - Uranus - Neptune At least 5 dwarf planets: Ceres - Pluto - Makemake - Haumea - Eris






36. Divided into two main types: large - low- density gas giants and smaller - rocky terrestrials - There are at least 341 identified _______ - 8 of which are in the Solar System






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






38. Loose collections of ice - dust - and small rocky particles - measuring a few kilometers or tens of kilometers across






39. This upslope wind is called a...






40. Seasons are marked by changes in the amount of sunlight - which in turn often cause cycles of dormancy in plants and hibernation in animals - These effects vary with latitude and with proximity to bodies of water






41. The precipitation that is intercepted by plant foliage and eventually evaporates back to the atmosphere rather than falling to the ground






42. Spiral - elliptical - and irregular form are speckled throughout the visible universe - Largest telescope has detected galaxies to its limit of several billion light - years






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






44. The movement (carrying away or displacement) of solids (sediment - soil - rock - and other particles) - usually by the agents of currents such as wind - water - or ice by downward or down - slope movement in response to gravity






45. Two high waters and two low waters each day - in most locations - tides are semidiurnal






46. The flow of water underground - in the vadose zone and aquifers - Subsurface water may return to the surface (as a spring or by being pumped) or eventually seep into the oceans
