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.

17. 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






18. Different visual appearance; when discovered - comets show a perceptible coma while asteroids do not






19. Rocks are placed into groups according to how they form...






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






21. 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






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






23. 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






24. Most sediments were deposited in beds that were originally horizontal - and any tilting is due to later earth movements






25. Zero degrees latitude - generally has a tropical climate (warm and wet); at the extreme northern and southern latitudes (polar regions) - the climate is very cold and dry






26. A semi - closed coastal body of water with one or more rivers or streams flowing into it - and with a free connection to the open sea - Often associated with high levels of biological diversity - They are made up of brackish water - Often given names






27. A land form that stretches above the surrounding land in a limited area - with a peak - Usually produced by the movement of lithospheric plates






28. 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






29. When the moon is at first quarter or third quarter - the sun - earth and moon form a 90- degree (right) angle with the earth at the vertex - The combined effect of this alignment of the sun - earth - and moon results in tidal ranges on the earth - Wh






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






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






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






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






34. The breakdown of rocks - soils and minerals through atmospheric chemicals or biologically produced chemicals (also known as biological weathering)






35. The stress is particularly severe in _________ - which are characterized by volcanism - metamorphism - deformation - and uplift






36. - 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
