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






2. Featherlike clouds that indicate fair weather






3. 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






4. The outermost part of the earth's interior is made up of two layers...






5. 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






6. Bbreaking along flat surfaces






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






8. 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






9. Stars with the highest ___________ appear blue - while stars with the lowest surface temperature appear red






10. The layers of sediment deposited in a quiet environment - Common sites of deposition are lakes - deltas at the mouths of rivers - beaches and sandbars along the coast - and (most important) the marine environment






11. How much matter is in the object






12. Occurs at the instant when the sun's position in the sky is at its greatest angular distance on the other side of the equatorial plane from the observer's hemisphere - Depending on the shift of the calendar - the winter solstice occurs some time betw






13. Texture is important in classifying ______ sedimentary rocks






14. 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






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






16. Some infiltration stays close to the land surface and can seep back into surface - water bodies (and the ocean) as...






17. 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






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






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






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






21. 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






22. Somewhat cooler disturbances in the photosphere






23. 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






24. Take up about 1/3 of the earth's land surface - many are formed by rain shadows - Usually have a large diurnal (day) and seasonal temperature range - with high daytime temperatures






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






26. 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...






27. Solar Atmosphere is divided into the inner chromosphere with explosive prominences and the outer corona - a glowing halo visible only during a total eclipse - Constantly emitting particles as a...






28. Affected by factors such as weathering and impurities






29. Younger beds were originally deposited above older beds






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






31. Continental tropical (dry - warm air)






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






33. The resulting dust layer would act as a shield - blocking out much of the sun's rays - This would result in lower global temperatures and a general _____ of the earth






34. 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






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






36. Volcanoes can be caused by '____________'; these so - called hotspots - as in Hawaii - can occur far from plate boundaries






37. Forms over the Tropics and is warm






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






39. This upslope wind is called a...






40. At any given time - regardless of season - the Northern and Southern Hemispheres experience...






41. 186000 miles/second






42. 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






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






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