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 difference between levels of ocean water at high and low tides






2. Water transpired from plants and evaporated from the soil






3. The rising of the earth's ocean surface caused by the tidal forces of the moon and the sun acting on the oceans






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






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

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






7. 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






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






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






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






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






12. 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






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






14. The runoff produced by melting snow






15. 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






16. The fossiliferous strata record is only the last __% of the earth's history






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






18. 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






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






20. Believed to originate at a much greater distance from the Sun - in a cloud (the Oort cloud) consisting of debris left over from the condensation of solar nebula - Comets are thrown from the outer planets or nearby stars - or as a result of collisions






21. This upslope wind is called a...






22. The movement of rainwater as it filters through soil and rocks into the ground - becoming groundwater






23. Weather occurs primarily due to density (temperature and moisture) differences between one location and another - These differences can occur due to the angle of the sun at any particular spot - which varies by latitude from the tropics






24. Somewhat cooler disturbances in the photosphere






25. 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.






26. 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






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






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






29. 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






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






31. Faulting and folding






32. 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






33. A major determiner of coastal climate






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






35. Large - scale movements of the earth's lithosphere - - The theory encompasses the older concepts of continental drift (first half of 20th century) and seafloor spreading (1960s)






36. 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






37. Earth movements - The result of forces within the earth - where temperature and pressure differences lead to instability






38. Temperature - pressure - and composition






39. 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






40. 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






41. Typically the tidal mouths of rivers and are often characterized by _____________ or silt carried in from terrestrial runoff - frequently from offshore






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

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






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






45. Forms over the Tropics and is warm






46. Mountains blocking the path of precipitation to the desert
