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






2. This upslope wind is called a...






3. 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...






4. The earth is believed to be about ___ billion years old






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






6. 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






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






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






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






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






11. A major determiner of coastal climate






12. 1 hour of time






13. The spectra of distant objects display a red shift - which is interpreted as meaning that they are rapidly receding from us - This apparent expansion of the universe has given rise to the big bang theory of cosmology - in which one primeval mass expl






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






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






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






17. 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






18. 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)






19. Air currents move clouds around the globe and cloud particles collide - grow - and fall out of the sky as ________ - Most of it falls back into the oceans or onto land - where the precipitation flows over the ground as surface runoff - portion of run






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






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






23. Large - dark clouds that indicate thunderstorms






24. 186000 miles/second






25. 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






26. The best determiner of climate - as it is consistently and directly correlated with temperature - other factors: Rain shadows - as well as water currents - elevation and so forth






27. 4 terrestrials: Mercury - Venus - Mars - Earth 4 gas giants: Jupiter - Saturn - Uranus - Neptune At least 5 dwarf planets: Ceres - Pluto - Makemake - Haumea - Eris






28. Occur when two plates push together - Such faults are strong and relatively deep - Where the strongest earthquakes occur Example: mountain building in the Himalayas and the Andes






29. The stress is particularly severe in _________ - which are characterized by volcanism - metamorphism - deformation - and uplift






30. Darkens the moon as the earth passes between it and the sun - casting a shadow on the moon - may be seen from anywhere the moon is visible - about half of the earth






31. 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






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






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






34. 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






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






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






37. 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






38. Comprised of the crust and the rigid uppermost part of the mantle - broken up into tectonic plates (7 major and many minor) - ride on the asthenosphere






39. 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

40. The tidal force produced by the sun is ____ as large as that produced by the moon






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






42. Piled in waves and indicate rain or snow






43. Rising air currents take the vapor up into the atmopshere where cooler temperatures cause it to condense into ____






44. 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






45. 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






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






47. A ______________ - such as the Mid - Atlantic Ridge - has examples of volcanoes caused by divergent tectonic plates pulling apart






48. Sometimes called minor planets or planetoids - Bodies






49. Forms over the Tropics and is warm






50. Volcanoes are also found in __________ - where the denser oceanic plates are forced under continental plates; this adds massive volumes of water to the mantle - allowing magma to melt more readily and rise to the surface to form volcanoes
