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






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






3. Used to arrange strata in a standard order - Used to measure the amount of radioactive decay in minerals and calculate the time at which the rock formed






4. Temperature - pressure - and composition






5. Huge systems of stars - Milky Way is estimated to have 100 billion stars arranged in a great disk






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






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






8. Bbreaking along flat surfaces






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






10. Occur when two plates pull away from each other - Such faults are generally weak and shallow Example: the Mid - Atlantic Range in the Atlantic Ocean






11. Travels in an orbit that is slightly elliptical (oval) - and so the distance from the sun ranges from 91.5 to 94.5 million miles - Its daily rotation deforms the earth to a flattened spheroid - with a polar radius slightly less than the equatorial ra






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






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






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






15. 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






16. Cirrus - Stratus - Cumulonimbus - Altostratus






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






18. Precipitation - Canopy interception - Snowmelt - Runoff - Percolation - Subsurface flow- Evaporation - Sublimation - Condensation






19. Some precipitation falls as ____ and can accumulate as ice caps and glaciers - which can store water for thousands of years






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






21. Form when dissolved mineral solutions crystalize out of lakes and oceans






22. 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






23. Classified as warm - water or cold - water currents






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






25. Igneous rock that cools beneath the earth's surface - Examples: plutons - dikes - and batholiths






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






27. A major determiner of coastal climate






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






29. The evaporation of these oceans is how we get most of our __________ - and their temperature determines our climate and wind patterns






30. The state change where a solid (ice or snow) changes directly to a gas (water vapor)






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






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






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






34. One tidal cycle per day






35. A region of the earth that has uniform standard time - usually referred to as the local time - divided into standard and daylight saving (or summer)






36. 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






37. The result of the buildup of once - living things






38. 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






39. Mountains blocking the path of precipitation to the desert

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






46. Two types of mountains are formed - depending on how the rock reacts to the tectonic forces






47. 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






48. A warm - water current that carries warm water from the Tropics to the Arctic regions of the North Atlantic Ocean - This accounts for higher temperatures and higher humidity on the Eastern Seaboard during the summer
