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. Some groundwater finds openings in the land surface and emerges as...






2. A major determiner of coastal climate






3. This upslope wind is called a...






4. Seas - gulfs - bays - and other names






5. Bbreaking along flat surfaces






6. 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






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






8. Occurs at the instant when the sun's position in the sky is at its greatest angular distance on the other side of the equatorial plane from the observer's hemisphere - Depending on the shift of the calendar - the winter solstice occurs some time betw






9. 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






10. Faulting and folding






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






12. Center: 3000

13. Occur when two plates push together - Such faults are strong and relatively deep - Where the strongest earthquakes occur Example: mountain building in the Himalayas and the Andes






14. 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






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






16. The tendency of a moving object to stay in a straight line or a stationary object to remain in place - Without _______ - a planet would be pulled into the sun






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






18. Erosion in many places is increased by human land use - Poor land - use practices include deforestation - overgrazing - unmanaged construction activity - and road building






19. The science that describes and interprets the earth Fields: - Geomorphology (land forms) - Petrology (rocks) - Stratigraphy (layered rocks) - Paleontology (fossils)






20. Water returns to the land surface at __________ than where it entered - under the force of gravity or gravity - induced pressures






21. 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






22. 1 hour of time






23. Maritime tropical (wet - warm air)






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






25. One tidal cycle per day






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






27. 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






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






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






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






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






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






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






34. 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






35. On maps - the characteristics of an air mass are represented by two letters: The lowercase letter represents ________ - and the uppercase letter represents temperature






36. 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






37. 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






38. 186000 miles/second






39. Mountains blocking the path of precipitation to the desert






40. 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






41. The degrees north or south of the equator






42. 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






43. The transformation of water from liquid to gas phases as it moves from the ground or bodies of water into the overlying atmosphere






44. Composed of the fragments of other types of rocks - Cover 75 to 80% of the earth's land area - Often deposited in distinct parallel layers - Weather and erosion break down other rock types into sediments - Over time - the sediments become cemented an
