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






2. Darkens the moon as the earth passes between it and the sun - casting a shadow on the moon - may be seen from anywhere the moon is visible - about half of the earth






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






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






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






6. Runoff and groundwater are stored as ________ in lakes






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






8. 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

9. Used to arrange strata in a standard order - Used to measure the amount of radioactive decay in minerals and calculate the time at which the rock formed






10. Believed to originate at a much greater distance from the Sun - in a cloud (the Oort cloud) consisting of debris left over from the condensation of solar nebula - Comets are thrown from the outer planets or nearby stars - or as a result of collisions






11. 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






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






13. A major determiner of coastal climate






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






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






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






17. Seasons are marked by changes in the amount of sunlight - which in turn often cause cycles of dormancy in plants and hibernation in animals - These effects vary with latitude and with proximity to bodies of water






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






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






21. The rising of the earth's ocean surface caused by the tidal forces of the moon and the sun acting on the oceans






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






23. Forms over water and is associated with wet air






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






25. 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






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. Mountains blocking the path of precipitation to the desert






28. Some precipitation falls as ____ and can accumulate as ice caps and glaciers - which can store water for thousands of years






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. Sometimes called minor planets or planetoids - Bodies






31. Forms over the Tropics and is warm






32. 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






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






34. After the moon has waxed through crescent - quarter - and gibbous phases - a ________ appears - At that time - the moon rises at sunset - and we see all of its illuminated side - Then the phase wanes gradually to another new moon






35. Result from the earth's axis being tilted to its orbital plane - NOT the result of the variation in the earth's distance to the sun (Because of its elliptical orbit - the earth as a whole is slightly warmer when away from the sun; this is because the






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






37. Not all runoff flows into rivers; much of it infiltrates into the ground through...






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






39. 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






40. A warm - water current that carries warm water from the Tropics to the Arctic regions of the North Atlantic Ocean - This accounts for higher temperatures and higher humidity on the Eastern Seaboard during the summer






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

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






43. Under solar conditions - gases are undergoing _____ to heavier elements with the increase of prodigious quantities of energy






44. One tidal cycle per day






45. Some infiltration stays close to the land surface and can seep back into surface - water bodies (and the ocean) as...






46. The atmosphere is a __________ - and so small changes to one part of the system can grow to have large effects on the system as a whole - This makes it difficult to accurately predict weather more than a few days in advance






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