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.

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. Forms over land and is associated with dry air






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






12. Officially defined as sustained sea surface temperature anomalies of magnitude greater than 0.5






13. 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

15. Bodies similar to the sun but immensely distant - Closest stars are 4 light - years away






16. 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






17. 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






18. Younger beds were originally deposited above older beds

23. Featherlike clouds that indicate fair weather






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






25. Solar Atmosphere is divided into the inner chromosphere with explosive prominences and the outer corona - a glowing halo visible only during a total eclipse - Constantly emitting particles as a...






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






27. The state change where a solid (ice or snow) changes directly to a gas (water vapor)






28. 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

31. Gas giants Jupiter - Saturn - Uranus and Neptune have diameters far larger than Earth's and have far greater masses






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






33. 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






34. Large - scale movements of the earth's lithosphere - - The theory encompasses the older concepts of continental drift (first half of 20th century) and seafloor spreading (1960s)

36. Around a new or full moon - when the sun - moon - and the earth form a line - the tidal forces due to the sun reinforce those of the moon - The tide's range is at a maximum and is called a spring tide (spring as in 'to jump/leap -' not the season)






37. 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






38. Maritime polar (wet - cold air)






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