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. How much matter is in the object






2. 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

7. A small Solar System body that orbits the Sun - When close enough to the sun - exhibits a visible coma (atmosphere) or a tail - both primarily from the effects of solar radiation upon the comet's nucleus - Have a variety of different orbital periods






8. Forms over water and is associated with wet air






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






10. The degrees north or south of the equator






11. Tends to move slowly and is replenished slowly - and so it can remain in aquifers for thousands of years






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






13. 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






14. 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






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






16. Cirrus - Stratus - Cumulonimbus - Altostratus






17. The science of the atmosphere and weather






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






19. 4 terrestrials: Mercury - Venus - Mars - Earth 4 gas giants: Jupiter - Saturn - Uranus - Neptune At least 5 dwarf planets: Ceres - Pluto - Makemake - Haumea - Eris






20. Natural chemical compounds that are the crystals that make up rocks - Each has a specific composition or narrow range of composition






21. Smooth layers of low clouds that indicate a chance of drizzle or snow






22. 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






23. 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






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






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






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






27. Characterized by similar temperatures and moisture levels






28. Oceans cover __ of the earth's surface






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






30. 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...






31. A semi - closed coastal body of water with one or more rivers or streams flowing into it - and with a free connection to the open sea - Often associated with high levels of biological diversity - They are made up of brackish water - Often given names






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






33. The breakdown of rocks - soils and minerals through direct contact with atmospheric conditions such as heat - water - ice - and pressure






34. 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






35. Nearest galaxy - about 20 million light - years away






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






37. 186000 miles/second






38. 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






39. Temperature - pressure - and composition






40. Condensed water vapor that falls to the earth's surface - Most precipitation occurs as rain - but also includes snow - hail - fog drip - graupel - and sleet






41. 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






42. The cold - water current that flows north to south off the _____________ keeps the West Coast fairly cool during the summer - Cold - water currents create cooler temperatures in areas that would otherwise be much warmer






43. 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






44. The transformation of water vapor to liquid water droplets in the air - producing clouds and fog
