CSET Subject 2: Science

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.

3. 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.






4. Is a substance composed of two or more elements






5. An ion






6. An atom that has a different number of neutrons than its normal amount.






7. Because carbon bonds readily with a variety of different elements and compounds - making possible the great chemical complexity necessary for life.

19. Are a progressive disturbance propagated from point to point (with regularity between points)






20. A bond formed when atoms share one or more of their valence electrons.






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