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. 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...






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






3. Characterized by unusually warm ocean temperatures in the eastern equatorial Pacific - warm current of nutrient - poor tropical water - heated by its eastward passage in the Equatorial Current - replaces the cold - nutrient - rich surface water of th






4. Texture is important in classifying ______ sedimentary rocks






5. The motive force behind land breezes and sea/lake breezes - also known as on - or off - shore winds - Land absorbs and radiates heat faster than water - but water releases heat over a longer period of time






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






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






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






9. 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






10. A ______________ - such as the Mid - Atlantic Ridge - has examples of volcanoes caused by divergent tectonic plates pulling apart






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






12. Can influence climate by sending tremendous volumes of dust - ash - and smoke into the atmosphere






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






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






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






16. 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






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






18. The North Pole is in the Arctic Ocean - and thus its temperature extremes are buffered by the water - The result is that the South Pole is consistently _______ during the southern winter than the North Pole during the northern winter






19. 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






20. Takes approx. seven and a half earth months to revolve around the sun - Takes approx. eight earth months to rotate on its axis - a day on ________ is longer than a year






21. Forms south of the Arctic and is cold






22. 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






23. The degrees north or south of the equator






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






25. 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






26. Igneous rock that forms on the earth's surface - Examples obsidian - basalt - and pumice






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






28. Occur when two plates slip past each other - Such faults are generally moderate and are relatively shallow Example: The San Andreas Fault






29. 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






30. Forms over the Tropics and is warm






31. Natural chemical compounds that are the crystals that make up rocks - Each has a specific composition or narrow range of composition






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






33. 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






34. 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






35. 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






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






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






38. 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






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

41. 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






42. An individual weighing 200 lbs on Earth would weigh more on a _______________ - Weight is a function of gravity






43. - The materials left over after the rock breaks down combine with organic material - The mineral content is determined by the parent material; thus - a soil derived from a single rock type can often be deficient in one or more minerals for good ferti
