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






2. Large - dark clouds that indicate thunderstorms






3. The degrees east or west of the prime meridian through Greenwich - England






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






5. Occur along plate boundaries






6. 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






7. 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






8. 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






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






10. Huge systems of stars - Milky Way is estimated to have 100 billion stars arranged in a great disk






11. Classified as warm - water or cold - water currents






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






13. 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






14. Sometimes called minor planets or planetoids - Bodies






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






16. Maritime polar (wet - cold air)






17. Forms over the Tropics and is warm






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






19. 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






20. Take up about 1/3 of the earth's land surface - many are formed by rain shadows - Usually have a large diurnal (day) and seasonal temperature range - with high daytime temperatures






21. The degrees north or south of the equator






22. Bbreaking along flat surfaces






23. Loose collections of ice - dust - and small rocky particles - measuring a few kilometers or tens of kilometers across






24. Mountains blocking the path of precipitation to the desert






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






26. 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






27. 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






28. 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






29. Largest zone of the planet (68%); crystalline silicates - rich in magnesium - calcium - and iron; very hot and mainly solid - but local melting to magma is the source of volcanic eruptions






30. How much matter is in the object






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






32. The runoff produced by melting snow






33. 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






34. Forms over water and is associated with wet air






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






36. Travels in an orbit that is slightly elliptical (oval) - and so the distance from the sun ranges from 91.5 to 94.5 million miles - Its daily rotation deforms the earth to a flattened spheroid - with a polar radius slightly less than the equatorial ra






37. Common: wind - clouds - rain - snow - fog - dust storms - Less common: natural disasters such as tornadoes - hurricanes - and ice storms






38. 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


39. 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






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






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


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






43. Center: 3000


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






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


46. 186000 miles/second






47. Oceans cover __ of the earth's surface






48. Both gravity and inertia work together to keep planets in orbit around the sun - Inertia makes a planet travel in a straight line






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






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