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






2. Theory that the earth's continents were originally united as a supercontinent - Pangaea - Established by Alfred Wegener in the early 1900s






3. Center: 3000


4. The farther from the tropics you are positioned - the ________ the angle of the sun - This causes those locations to be cooler due to the indirect sunlight






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






6. The breakdown of rocks - soils and minerals through atmospheric chemicals or biologically produced chemicals (also known as biological weathering)






7. The degrees north or south of the equator






8. The rising of the earth's ocean surface caused by the tidal forces of the moon and the sun acting on the oceans






9. A ______________ - such as the Mid - Atlantic Ridge - has examples of volcanoes caused by divergent tectonic plates pulling apart






10. 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






11. An area of frequent earthquakes and volcanic eruptions associated with the plate boundaries surrounding the Pacific Ocean - In a 40000 km horseshoe shape - associated with a nearly continuous series of oceanic trenches - volcanic arcs - and volcanic






12. 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






13. 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






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






15. Large - dark clouds that indicate thunderstorms






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






17. Thought to originate in the Kuiper Belt - or associated scattered discs - which lie beyond the orbit of Neptune






18. 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






19. (in descending order of size) the Pacific Ocean - the Atlantic Ocean - the Indian Ocean - the Southern Ocean and the Arctic Ocean






20. Oceans cover __ of the earth's surface






21. Igneous rock that forms on the earth's surface - Examples obsidian - basalt - and pumice






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






23. Forms south of the Arctic and is cold






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






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






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






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






28. Maritime tropical (wet - warm air)






29. 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






30. Maritime polar (wet - cold air)






31. Most sediments were deposited in beds that were originally horizontal - and any tilting is due to later earth movements






32. Air currents move clouds around the globe and cloud particles collide - grow - and fall out of the sky as ________ - Most of it falls back into the oceans or onto land - where the precipitation flows over the ground as surface runoff - portion of run






33. 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






34. Pulls the planets toward the sun - while their inertia keeps them moving forward in an elliptical orbit around the sun


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






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






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






38. 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






39. The tidal force produced by the sun is ____ as large as that produced by the moon






40. Featherlike clouds that indicate fair weather






41. 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






42. 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






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






44. A major determiner of coastal climate






45. There are approx. _____ days between each lunar cycle
