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 sun and oceans can also affect the weather of land - If the sun heats ocean waters for a period of time - water can evaporate - Once evaporated into the air - the moisture can spread over nearby land - thus making it cooler

2. The runoff produced by melting snow






3. 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






4. 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






5. Common: wind - clouds - rain - snow - fog - dust storms - Less common: natural disasters such as tornadoes - hurricanes - and ice storms






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

7. Water returns to the land surface at __________ than where it entered - under the force of gravity or gravity - induced pressures






8. Forms over water and is associated with wet air






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






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






11. 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






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






13. Continental polar (dry - cold air)






14. Less than 1% of the earth; this relatively thin zone (5 to 25 miles) contains the only rocks we can study - even in the deepest mines or drill holes






15. After the moon has waxed through crescent - quarter - and gibbous phases - a ________ appears - At that time - the moon rises at sunset - and we see all of its illuminated side - Then the phase wanes gradually to another new moon






16. Characterized by similar temperatures and moisture levels






17. When the moon is at first quarter or third quarter - the sun - earth and moon form a 90- degree (right) angle with the earth at the vertex - The combined effect of this alignment of the sun - earth - and moon results in tidal ranges on the earth - Wh






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






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






20. 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






21. Result from the earth's axis being tilted to its orbital plane - NOT the result of the variation in the earth's distance to the sun (Because of its elliptical orbit - the earth as a whole is slightly warmer when away from the sun; this is because the






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






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






24. 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






25. Different visual appearance; when discovered - comets show a perceptible coma while asteroids do not






26. 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.






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






28. Tides may be...






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






30. 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






31. The motive force behind land breezes and sea/lake breezes - also known as on - or off - shore winds - Land absorbs and radiates heat faster than water - but water releases heat over a longer period of time






32. This upslope wind is called a...






33. 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






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






35. Large - dark clouds that indicate thunderstorms






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






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






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






39. Deviates by an angle of approximately 23.5 degrees - Thus - at any given time during summer or winter - one part of the planet is more directly exposed to the rays of the sun - This exposure alternates as the earth revolves in its orbit






40. Water transpired from plants and evaporated from the soil






41. 186000 miles/second






42. 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)






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