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. Generally forms deep in the mantle as one type of rock changes into another - Due to intense pressure - can show signs of bending and distortion - Examples: schist - marble - gneiss - and slate






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






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






4. 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






5. 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






6. Maritime polar (wet - cold air)






7. 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






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






9. 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






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






11. The variety of ways by which water moves across the land - This includes both surface runoff and channel runoff - As it flows - the water may percolate into the ground - evaporate into the air - become stored in lakes or reservoirs - or be extracted






12. Volcanoes are generally found where ________ are diverging or converging






13. 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






14. Divided into two main types: large - low- density gas giants and smaller - rocky terrestrials - There are at least 341 identified _______ - 8 of which are in the Solar System






15. Forms south of the Arctic and is cold






16. Temperature - pressure - and composition






17. 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






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






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






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






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






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






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






25. Large - dark clouds that indicate thunderstorms






26. Faulting and folding






27. Characterized by similar temperatures and moisture levels






28. Traces of ancient life preserved in the strata as shells - footprints - and the like - Soft plant and animal tissues decompose quickly in the presence of decay bacteria - which exist wherever oxygen exists






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






30. The degrees north or south of the equator






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






32. The breakdown of rocks - soils and minerals through direct contact with atmospheric conditions such as heat - water - ice - and pressure






33. The runoff produced by melting snow






34. 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






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


36. The result of the buildup of once - living things






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






38. Distance to closest stars can be calculated by measuring the _________ - a slight shift in apparent position against the background of more distant stars as the earth travels around the sun






39. 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






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






41. Comprised of the crust and the rigid uppermost part of the mantle - broken up into tectonic plates (7 major and many minor) - ride on the asthenosphere






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






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






44. Some water infiltrates deep into the ground and replenishes ________ - which store huge amounts of freshwater for long periods of time
