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






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






3. Ancient astronomers found that eclipses occurred periodically and learned to predict them accurately - Lunar and solar






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






5. (or summer time zones) include an offset (typically +1 hour) for daylight saving time






6. Human civilization has lasted only _____ years






7. Affected by factors such as weathering and impurities






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






9. Younger beds were originally deposited above older beds






10. Continental polar (dry - cold air)






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






12. Forms over water and is associated with wet air






13. 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






14. Test the item against materials of known hardness; for example - use your fingernail or the graphite in a pencil to attempt to scratch the items. This process should result in assigning a relative hardness to the unknown items.






15. 186000 miles/second






16. 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






17. Continental tropical (dry - warm air)






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






19. The movement (carrying away or displacement) of solids (sediment - soil - rock - and other particles) - usually by the agents of currents such as wind - water - or ice by downward or down - slope movement in response to gravity






20. 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






21. Nearest galaxy - about 20 million light - years away






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






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


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






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






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






27. One tidal cycle per day






28. The lateral movement of the plates is typically at speeds of ___ mm annually






29. Forms over land and is associated with dry air






30. An opening - or rupture - in a planet's surface or crust - which allows hot molten rock - ash - and gases to escape from below the surface - Volcanic activity involving the extrusion of rock tends to form mountains or features like mountains over a p






31. 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






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. This upslope wind is called a...






34. 4 terrestrials: Mercury - Venus - Mars - Earth 4 gas giants: Jupiter - Saturn - Uranus - Neptune At least 5 dwarf planets: Ceres - Pluto - Makemake - Haumea - Eris






35. 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

38. The Pacific Ring of Fire has examples of volcanoes caused by ___________ coming together






39. Different visual appearance; when discovered - comets show a perceptible coma while asteroids do not






40. 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






41. 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






42. 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






43. 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






44. The flow of water underground - in the vadose zone and aquifers - Subsurface water may return to the surface (as a spring or by being pumped) or eventually seep into the oceans
