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. An individual weighing 200 lbs on Earth would weigh more on a _______________ - Weight is a function of gravity






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






3. 1 hour of time






4. Forms over the Tropics and is warm






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






6. 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...






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






8. 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






9. A region of the earth that has uniform standard time - usually referred to as the local time - divided into standard and daylight saving (or summer)






10. Seasons are marked by changes in the amount of sunlight - which in turn often cause cycles of dormancy in plants and hibernation in animals - These effects vary with latitude and with proximity to bodies of water






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






12. The sun is not at the center of the disk - but out toward the perimeter - and is revolving around the ________






13. 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






14. Younger beds were originally deposited above older beds






15. The variety of ways by which water moves across the land - This includes both surface runoff and channel runoff - As it flows - the water may percolate into the ground - evaporate into the air - become stored in lakes or reservoirs - or be extracted






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






17. Characterized by unusually warm ocean temperatures in the eastern equatorial Pacific - warm current of nutrient - poor tropical water - heated by its eastward passage in the Equatorial Current - replaces the cold - nutrient - rich surface water of th






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






19. 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






20. 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






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






22. 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






23. Occur along plate boundaries






24. Some groundwater finds openings in the land surface and emerges as...






25. 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






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






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






28. 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






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






30. 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






31. 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






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






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






34. Temperature - pressure - and composition






35. 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






36. Formed from calcium carbonate - also an example of chemical sedimentary rocks - like roock salt - can contain organic or once - living matter and can record the history of that matter's formation in features such as strata - fossil evidence - and rip






37. The degrees east or west of the prime meridian through Greenwich - England






38. 4 terrestrials: Mercury - Venus - Mars - Earth 4 gas giants: Jupiter - Saturn - Uranus - Neptune At least 5 dwarf planets: Ceres - Pluto - Makemake - Haumea - Eris






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

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






41. Continental tropical (dry - warm air)






42. The atmosphere is a __________ - and so small changes to one part of the system can grow to have large effects on the system as a whole - This makes it difficult to accurately predict weather more than a few days in advance






43. Piled in waves and indicate rain or snow






44. 186000 miles/second






45. 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






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






47. How much matter is in the object






48. This upslope wind is called a...
