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






2. Oceans cover __ of the earth's surface






3. The degrees north or south of the equator






4. 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






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






6. 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






7. Volcanoes are also found in __________ - where the denser oceanic plates are forced under continental plates; this adds massive volumes of water to the mantle - allowing magma to melt more readily and rise to the surface to form volcanoes






8. 1 hour of time






9. 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






10. Runoff and groundwater are stored as ________ in lakes






11. 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






12. The transformation of water vapor to liquid water droplets in the air - producing clouds and fog






13. Takes place when the moon passes between the earth and the sun - with the moon blocking the sunlight for about two minutes - A total ___________ may be seen only from a small zone on the earth






14. Texture is important in classifying ______ sedimentary rocks






15. 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






16. 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






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






18. Forms south of the Arctic and is cold






19. 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






20. Somewhat cooler disturbances in the photosphere






21. Spiral - elliptical - and irregular form are speckled throughout the visible universe - Largest telescope has detected galaxies to its limit of several billion light - years






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






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






24. 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






25. Tides may be...






26. 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






27. Occur along plate boundaries






28. The strong temperature contrast between polar and tropical air gives rise to the ________






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






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






31. Mountains blocking the path of precipitation to the desert






32. Hotspot volcanoes are also found elsewhere in the Solar System - especially on...






33. 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






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






35. 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

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. 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






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






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






40. 186000 miles/second






41. The science of the atmosphere and weather






42. Cirrus - Stratus - Cumulonimbus - Altostratus






43. The outermost part of the earth's interior is made up of two layers...






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






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






46. One tidal cycle per day






47. The source of energy for evaporation is primarily through ___________






48. Travels around the earth each month - - Distance from the earth averages 237000 miles - Has rugged topography formed billions of years ago by volcanic eruptions and meteorite impacts - Mass is 1/6th that of Earth






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






50. 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
