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.

8. The amount of matter that makes up an atom. You can estimate an atom's atomic mass by adding up the total number of protons and neutrons.






9. 1. neutral charge 2. located in the nucleus 3. mass is 1 AMU






10. Is an object's rate of motion = Distance/Time






11. Begin as huge clouds of dust and other particles called nebulas.






12. Matter and energy have the properties of both particles and waves






13. H2O + CO2 --> CH2O + O2






14. Is a change in velocity

16. 1. puzzle piece argument 2. sea floor spreading 3. fossil records






17. Is the smallest unit of an element that still has the properties of that element.






18. Anything that has mass and takes up space






19. Grain like organelles that produce proteins






20. Has the same number of protons and neutrons






21. States that all of the Earth's continents at one time were joined as a single 'super - continent' called Pangaea. Over time - the continents drifted apart.






22. The measure of the kinetic energy in a substance's molecules. Simply - temperature is atomic motion.






23. Cell begins to split






24. A bond in which on atom loses an electron to form a positive ion and the other gains an electron to form a negative ion - creating an electrostatic force which holds them together.






25. The types of organisms an ecosystem can support is primarily determined by the amount of...






26. 1. gravity 2. magnetism 3. friction (think of a falling sheet of paper vs. a falling book)






27. 1. prophase 2. metaphase 3. anaphase 4. telophase






28. 1. the more massive either or both bodies are - the greater the gravitational force between them. 2. the further apart two bodies are - the lesser the gravitational force between them.






29. 1. convergent 2. divergent 3. transform






30. Is the process of storing energy through photosynthesis and later releasing it through respiration.






31. Refers to the vast periods of time over which the Earth changes.






32. Unless an object is moving in a vacuum - the object causes...






33. Converts energy from food to energy the cell can use






34. 1. negative charge 2. located in the nucleus 3. mass is about 1/1836th of an AMU






35. When the Moon or the Sun are pulling at perpendicular angles we get less extreme tides.






36. By wind which stirs the ocean's surface of great distances.






37. That matter cannot be created or destroyed; it simply changes form.






38. Is a method of separating ions within a substance by passing electrical current through the substance






39. Causes beneficial traits to be propagated and detrimental traits to be eliminated.






40. Occur because the shadow of the Earth or the Moon is cast onto the other body.






41. Our solar system is made up of numerous bodies which orbit the Sun due to...
