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






2. The science of the atmosphere and weather






3. Zero degrees latitude - generally has a tropical climate (warm and wet); at the extreme northern and southern latitudes (polar regions) - the climate is very cold and dry






4. Theory that the earth's continents were originally united as a supercontinent - Pangaea - Established by Alfred Wegener in the early 1900s






5. Occur twice a year - when the tilt of the earth's axis is oriented neither from nor to the sun - causing the sun to be located vertically above a point on the equator - The name derived from the Latin aequus (equal) and nox (night) - because at the e






6. Takes approx. seven and a half earth months to revolve around the sun - Takes approx. eight earth months to rotate on its axis - a day on ________ is longer than a year






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






8. Form when magma or lava cools and solidifies - Depending on the rate of cooling - can contain visible crystals - while others can appear glassy






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. A ______________ - such as the Mid - Atlantic Ridge - has examples of volcanoes caused by divergent tectonic plates pulling apart






11. Characterized by similar temperatures and moisture levels






12. Paleontology: Fossil evidence indicates the similarity of fossils on both sides of the Atlantic Ocean - Continental 'jigsaw puzzle': The outlines of the continents seem to fit together






13. A small Solar System body that orbits the Sun - When close enough to the sun - exhibits a visible coma (atmosphere) or a tail - both primarily from the effects of solar radiation upon the comet's nucleus - Have a variety of different orbital periods






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






15. Maritime polar (wet - cold air)






16. 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






17. Refers to the long - term weather patterns of a large geographical area and takes into account temperature - humidity - and precipitation






18. 186000 miles/second






19. Continental tropical (dry - warm air)






20. Somewhat cooler disturbances in the photosphere






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






22. Ancient astronomers found that eclipses occurred periodically and learned to predict them accurately - Lunar and solar






23. Sometimes called minor planets or planetoids - Bodies






24. Around a new or full moon - when the sun - moon - and the earth form a line - the tidal forces due to the sun reinforce those of the moon - The tide's range is at a maximum and is called a spring tide (spring as in 'to jump/leap -' not the season)






25. The major mountains tend to occur in __________ - indicating tectonic plate boundaries and activity






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






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






28. The science that describes and interprets the earth Fields: - Geomorphology (land forms) - Petrology (rocks) - Stratigraphy (layered rocks) - Paleontology (fossils)






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






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






31. The transformation of water from liquid to gas phases as it moves from the ground or bodies of water into the overlying atmosphere






32. Can influence climate by sending tremendous volumes of dust - ash - and smoke into the atmosphere






33. 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






34. 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






35. How much matter is in the object






36. The process of chemical or physical breakdown of earth rocks - soils - and their minerals






37. 1 hour of time






38. 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






39. Some water infiltrates deep into the ground and replenishes ________ - which store huge amounts of freshwater for long periods of time






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






41. Continental polar (dry - cold air)






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






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






44. Large - dark clouds that indicate thunderstorms






45. Faulting and folding






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






47. The strength of gravity in our solar system depends on both the masses of the celestial objects and the _______ between them






48. Volcanoes can also form where there is stretching and thinning of the...
