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. Affected by factors such as weathering and impurities






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






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






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






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






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

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






8. 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






9. Somewhat cooler disturbances in the photosphere






10. 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






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






12. Forms over land and is associated with dry air






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






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






15. Tides may be...






16. The farther from the tropics you are positioned - the ________ the angle of the sun - This causes those locations to be cooler due to the indirect sunlight






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






18. Characterized by unusually warm ocean temperatures in the eastern equatorial Pacific - warm current of nutrient - poor tropical water - heated by its eastward passage in the Equatorial Current - replaces the cold - nutrient - rich surface water of th






19. Comprises one global - interconnected body of salt water often (though generally recognized as several separate oceans) - A continuous body of water with relatively free interchange among its parts






20. 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






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






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






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






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






25. Formed by sodium chloride






26. 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)






27. Sun heats water in the oceans - Water evaporates as vapor into the air - Ice and snow can sublimate directly into water vapor...- Over time - the water reenters the ocean - where the water cycle started






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






29. Evaporation often implicitly includes ___________ from plants - although together they are specifically referred to as evapotranspiration






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






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






32. 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






33. The North Pole is in the Arctic Ocean - and thus its temperature extremes are buffered by the water - The result is that the South Pole is consistently _______ during the southern winter than the North Pole during the northern winter






34. This scale assigns a fixed number to 10 reference materials. Talc (1) is the softest and diamond (10) is the hardest

36. Forms over the Tropics and is warm






37. Seas - gulfs - bays - and other names






38. Pulls the planets toward the sun - while their inertia keeps them moving forward in an elliptical orbit around the sun

39. 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






40. 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...






41. Oceans cover __ of the earth's surface






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






43. 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






44. Characterized by unusually warm ocean temperatures in the same area - Atlanta tropical cyclone activity is generally enhanced during La Nina - Often follows the El Nino - especially when the latter is strong
