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






2. The center of the sun may have a temperature of millions of degrees; the visible surface - the ______ - is about 6000






3. 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






4. Forms over land and is associated with dry air






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






7. A natural flow of water - usually freshwater - traveling toward an ocean - a lake - or another stream






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






9. Younger beds were originally deposited above older beds






10. The process of chemical or physical breakdown of earth rocks - soils - and their minerals






11. One tidal cycle per day






12. Due to a combination of differential heating and geometry - hen the sun rises - it is the tops of the mountain peaks which receive first light - and as the day progresses - the mountain slopes take on a greater heat load than the valleys - This resul






13. Further caused by the elliptical orbit of the earth - Earth reaches perihelion (the point in its orbit closest to the sun) in January - and it reaches aphelion (farthest point from the sun) in July - Also depend on factors such as proximity to oceans






14. 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)






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






16. Some isolated mountains were produced by volcanoes - including many apparently ________ that reach a great height above the ocean floor






17. Cirrus - Stratus - Cumulonimbus - Altostratus






18. Sedimentary rocks containing large fragments of other rock material - e.g. Sandstone






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






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






21. 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






22. Piled in waves and indicate rain or snow






23. Affected by factors such as weathering and impurities






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






25. Sometimes called minor planets or planetoids - Bodies






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






27. 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






28. Under solar conditions - gases are undergoing _____ to heavier elements with the increase of prodigious quantities of energy






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






30. The process in which one type of rock changes into another






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. Large - dark clouds that indicate thunderstorms






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






34. Some precipitation falls as ____ and can accumulate as ice caps and glaciers - which can store water for thousands of years






35. 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






36. 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






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






38. Featherlike clouds that indicate fair weather






39. 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






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

42. Precipitation - Canopy interception - Snowmelt - Runoff - Percolation - Subsurface flow- Evaporation - Sublimation - Condensation






43. 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






44. Tides may be...






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