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. Cirrus - Stratus - Cumulonimbus - Altostratus






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






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






4. 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






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






6. 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






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






8. Evaporation often implicitly includes ___________ from plants - although together they are specifically referred to as evapotranspiration






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






10. 1 hour of time






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






12. 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






13. One tidal cycle per day






14. Characterized by similar temperatures and moisture levels






15. 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






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

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






18. A warm - water current that carries warm water from the Tropics to the Arctic regions of the North Atlantic Ocean - This accounts for higher temperatures and higher humidity on the Eastern Seaboard during the summer






19. 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






20. 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






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






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






23. Forms over the Tropics and is warm






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






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






26. Hotspot volcanoes are also found elsewhere in the Solar System - especially on...






27. Forms over land and is associated with dry air






28. The North Pole is in the Arctic Ocean - and thus its temperature extremes are buffered by the water - The result is that the South Pole is consistently _______ during the southern winter than the North Pole during the northern winter






29. Zero degrees latitude - generally has a tropical climate (warm and wet); at the extreme northern and southern latitudes (polar regions) - the climate is very cold and dry






30. 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






31. 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

32. Method of using the present to interpret the past - Processes occurring today are observed carefully and their effects are measured - Then - geologists assume that similar effects in ancient rocks were caused by processes similar to those of the pres






33. 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






34. 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






35. 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






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






37. Younger beds were originally deposited above older beds






38. Occur when two plates slip past each other - Such faults are generally moderate and are relatively shallow Example: The San Andreas Fault






39. Featherlike clouds that indicate fair weather






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






41. The precipitation that is intercepted by plant foliage and eventually evaporates back to the atmosphere rather than falling to the ground






42. 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






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






44. Loose collections of ice - dust - and small rocky particles - measuring a few kilometers or tens of kilometers across






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






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






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






48. The difference between levels of ocean water at high and low tides






49. Human civilization has lasted only _____ years






50. 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
