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






2. The result of the buildup of once - living things






3. The lateral movement of the plates is typically at speeds of ___ mm annually






4. An area of frequent earthquakes and volcanic eruptions associated with the plate boundaries surrounding the Pacific Ocean - In a 40000 km horseshoe shape - associated with a nearly continuous series of oceanic trenches - volcanic arcs - and volcanic






5. Cirrus - Stratus - Cumulonimbus - Altostratus






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






7. Take up about 1/3 of the earth's land surface - many are formed by rain shadows - Usually have a large diurnal (day) and seasonal temperature range - with high daytime temperatures






8. Due to a combination of differential heating and geometry - hen the sun rises - it is the tops of the mountain peaks which receive first light - and as the day progresses - the mountain slopes take on a greater heat load than the valleys - This resul






9. The difference between levels of ocean water at high and low tides






10. Rising air currents take the vapor up into the atmopshere where cooler temperatures cause it to condense into ____






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






12. Somewhat cooler disturbances in the photosphere






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






14. One tidal cycle per day






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






16. Younger beds were originally deposited above older beds






17. The spectra of distant objects display a red shift - which is interpreted as meaning that they are rapidly receding from us - This apparent expansion of the universe has given rise to the big bang theory of cosmology - in which one primeval mass expl






18. Characterized by similar temperatures and moisture levels






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






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






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






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






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






24. Typically the tidal mouths of rivers and are often characterized by _____________ or silt carried in from terrestrial runoff - frequently from offshore






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

26. 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






27. 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






28. Thought to originate in the Kuiper Belt - or associated scattered discs - which lie beyond the orbit of Neptune






29. Bbreaking along flat surfaces






30. 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






31. 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






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






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






34. Some isolated mountains were produced by volcanoes - including many apparently ________ that reach a great height above the ocean floor






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






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






37. 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






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






39. Classified as warm - water or cold - water currents






40. Method of using the present to interpret the past - Processes occurring today are observed carefully and their effects are measured - Then - geologists assume that similar effects in ancient rocks were caused by processes similar to those of the pres






41. 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






42. The Pacific Ring of Fire has examples of volcanoes caused by ___________ coming together






43. Occur along plate boundaries






44. Form when magma or lava cools and solidifies - Depending on the rate of cooling - can contain visible crystals - while others can appear glassy






45. Featherlike clouds that indicate fair weather






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






47. 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






48. 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
