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. 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






2. 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...






3. Featherlike clouds that indicate fair weather






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






5. Forms south of the Arctic and is cold






6. Characterized by unusually warm ocean temperatures in the same area - Atlanta tropical cyclone activity is generally enhanced during La Nina - Often follows the El Nino - especially when the latter is strong






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






8. Volcanoes can also form where there is stretching and thinning of the...

9. 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

10. Officially defined as sustained sea surface temperature anomalies of magnitude greater than 0.5






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






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






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






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






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






16. Cirrus - Stratus - Cumulonimbus - Altostratus






17. 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






18. Characterized by similar temperatures and moisture levels






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






20. Water transpired from plants and evaporated from the soil






21. Almost all familiar weather phenomena occur in the __________ (the lower part of the atmosphere)






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. 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






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






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






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






27. Seas - gulfs - bays - and other names






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






29. A major determiner of coastal climate






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






31. Forms over land and is associated with dry air






32. 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






33. 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






34. 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






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

36. 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






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






38. 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






39. Takes approx. seven and a half earth months to revolve around the sun - Takes approx. eight earth months to rotate on its axis - a day on ________ is longer than a year






40. 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

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






49. 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
